     First steps connection + amplifier

  8. Now the steps to follow are the same as from step 6. of a DTC without amplifier, described above.

Point-to-Point configuration

• Basic radio configuration

  Once the website has been accessed, follow the steps below which show the parameters that need to be modified for a correct operation and pairing of the radios.

  Note

  This is an example of the radio configuration linked to a ground unit.

  Note

  After making any changes, the application will ‘ask’ to Save or Cancel the changes. An example is shown below:

  

  Save or Cancel changes

  1. Global Setup \(\rightarrow\) General Settings: To easily identify each radio in a mesh, the user can rename the radio as desired:

     

     General settings configuration

     Note

     The radio related to the air unit also has its own personalised name:

     

     General settings air configuration

  2. Presets.

     • Mesh Settings: Some of the parameters configured in this menu are always displayed at the top of the application.

       Caution

       It is recommended that software for all devices in a Mesh network should be at the same version to avoid potential compatibility issues.

       

       Mesh settings configuration

       • Operation mode: Select Single Mesh.

       • Mesh ID: The Mesh ID must be the same on all units in the Mesh network. The Mesh ID tells the unit which network it belongs to, for example, all NETNodes on Mesh ID 1 will communicate with each other. The Mesh ID must be set to a non-zero value.

       • Node Id: The node ID must be unique in the Mesh network for each device.

         Note

         A node can automatically reassign its Node ID at power up if it finds a conflict with an existing node.

       • Operating range: A larger range allows the Mesh network to operate over a bigger distance at the expense of bitrate.

       • Enable transmitter: Set the checkbox to switch the RF power on.

       • Frequency: Set the desired transmission frequency. 2450 MHz recommended.

         Warning

         Be careful when choosing the frequency. The user may see interference with the Wifi frequency band, consult the radio spectrum.

       • Channel bandwith: Select the desired bandwidth from the drop-down list. Lower bandwidths provide greater range at the expense of data throughput. 10 MHz is recommended.

       • Output attenuation: The level of attenuation in dB that is applied to the output (from 0 to 32). 0 dB of attenuation is recommended

       • RF output port: The transmitter has two COFDM antennas, A and B. A is selected as the output antenna by default, but the user can select A or both if required.

       • PA linearity: High linearity improves the COFDM shoulder performance at the expense of power consumption.

         Usually used when working with power amplifiers which must have excellent shoulder performance to operate, or for improved adjacent channel performance.

       Warning

       To ensure proper communication between the two radios, the radio linked to the air unit must have these same ‘Mesh settings’ except for the Node Id, as each node in the mesh has its own Id (starting with Id 0):

       

       Mesh settings air configuration

     Moreover, there are up to 16 different preset configurations that can be setup.

     All these settings are made for preset 1, which is highlighted with a blue background in the ‘Mesh settings’ tab to indicate that it is active. In addition, a ‘preset indicator’ with the current present is always displayed at the top right of the application, as shown in the figure below.

     

     Current preset configuration

     • Unit Settings:

       External Power Enable: There is an external power output which can be used to supply 12VDC (1A) to an external device. This could be a camera, GNSS antenna or other device.

       

       Unit settings configuration

  3. Data \(\rightarrow\) RS232 #1: In this menu the parameters of the RS232 port and the network settings are configured:

     

     RS232 #1 configuration

     • Data mode: UDP option is recommended. UDP packets are sent out and the system does not expect a reply. There is no way that the sending device can tell if the data arrived at the destination.

     • The value of the Baud rate, Parity and Stop Bits parameters must be the same as those configured in 1x PDI Builder.

       Note

       The data is assumed to be 8 bits.

     • Low latency: Low latency will minimise delay at the expense of bitrate, so if set, data tranfer will be less prone to bursts. Yes is recommended.

     • IP address: This should be the address of the radio receiving the data on the other end of the RS-232. In this case, as the radio connected to the ground unit is being configured, the IP of the radio linked to the air unit will be set.

     • IP port: This set an IP port to and from which the data will be transferred. It must be the same for both radios.

     Important

     For the radio connected to the air unit, the IP address to be configured is the address of the radio linked to the ground unit.

     

     RS232 #1 air unit configuration

  4. System \(\rightarrow\) Maintenance: This menu allows to import and export radio configurations.

     

     Maintenance configuration

     To import a configuration into the radio, it is first necesarry to choose a configuration from the local storage by clicking on the icon. Then, the ‘import button’ will already be available (colored in blue) to click on and consequently import the selected configuration. An example is shown below:

     

     Configuration selected

• Paired radios

  Once both radios have been configured with these settings, they should be paired. Therefore, if we connect them to the power supply and only one of them to the computer, we can access the Domo Node Finder software or directly the Web Browser control application to check if they are correctly paired.

  • Domo Node Finder software

    When 2 radios are paired, they will both appear here:

    

    Domo Node Finder - Radios paired

    As can be seen in the figure above, the connection type of each radio is indicated with different icons:

    • icon for the radio that is wiredly connected to the PC.

    • icon for the radio that is connected by link.

  • Web Browser control application

    When two radios are paired, this can be seen/checked directly in the ‘Dashboard’ of both radios.

    

    Radios paired - Dashboard

    Furthermore, it can be seen that the above figure is related to the radio that is connected by link, as it is indicated at the top of the application with the label Over radio link.

    

    Apps \(\rightarrow\) Tactical Display: Here the user can check the connection and the quality of the signal connection of both radios:

    

    Radios paired - Tactical Display

    • Map display: The color of the link between nodes indicates the quality of the signal. The colors range from green (reliable link) to red (unreliable link). If no link is displayed, it means that communication has been lost.

    • TX info: TX info should be selected to check the quality of the signal connection.

      • Token Tx retries: In a Mesh network, transmission is arbitrated by passing a token between nodes. This tab displays the number of token retries that have been needed for each node. It must be 0 with occasional 1 for a proper communication.

        Caution

        Higher values will have an undesirable effect on system performance. If problems occur, check for interference and that there is no other Mesh system operating on the same or adjacent frequency.

Point-to-Multipoint configuration

It is possible that the user wants to make a point-to-multipoint radio connection, i.e. there will be one radio sending commands to several radios, so there will be at least 3 radios.

The following is the configuration required for this type of connection.

• Radio configuration

  The modifications to be made to the basic configuration explained above for the point-to-point application are detailed below.

  Note

  This example has been made with 3 radios (3 nodes in a mesh).

  1. Presets \(\rightarrow\) Mesh Settings: The Node ID must be different for each node in the mesh.

     

     Mesh settings ground configuration

     

     Mesh settings air configuration

     

     Mesh settings base configuration

     In the figures above, the user can see that the node ID is displayed at the top of the application at all times.

  2. Data \(\rightarrow\) RS232 #1: The Multicast data mode must be configured. This data mode allows a single node to send RS232/RS485 data to multiple nodes in the system. And it also creates a unicast data return channel.

     The radio linked to the ground unit is configured as the ‘Point’ that sends the commands.

     

     RS232 #1 ground configuration

     • Data mode: Multicast source must be selected.

     • IP address: To send the data to all receivers the IP address must set to 255.255.255.255.

     • Multicast address: It must be the same for all radios, avoiding the 244.0.0.X address range.

       The address must be different from any multicast streaming and data channels.

     Then, the radios linked to the air and base units receive those commands:

     

     RS232 #1 air unit configuration

     

     RS232 #1 base unit configuration

     • Data mode: Multicast sink must be selected.

     • IP address: The IP address of the radio linked to the ground unit is set.

     • Multicast address: It must be the same for all radios, avoiding the 244.0.0.X address range.

       The address must be different from any multicast streaming and data channels.

• Paired radios

  Once the radios have been configured with these settings, they should be paired. Therefore, if we connect them to the power supply and only one of them to the computer, we can access the Domo Node Finder software or directly the Web Browser control application to check if they are correctly paired.

  • Domo Node Finder software

    When 3 radios are paired, they will appear here:

    

    Domo Node Finder - 3 radios paired

    As can be seen in the figure above, there is 1 radio wiredly connected to the PC and 2 radios connected by link.

  • Web Browser control application

    When 3 radios are paired, this can be seen/checked directly in the ‘Dashboard’ of the three radios.

    

    Radios paired - Dashboard

    Furthermore, it can be seen that the above figure is related to a radio that is connected by link, as it is indicated at the top of the application with the label Over radio link.

    • Apps \(\rightarrow\) Tactical Display: Here the user can check the connection and the quality of the signal connection of the radios:

      

      Radios paired - Tactical Display

   LAN Interfaces Settings

   By selecting the Edit or Add buttons, the LAN network interface can be configured or additional LAN interfaces can be created.

   

   LAN Configuration:

   

   LAN Configuration - Ground unit

   

   LAN Configuration - Air unit

   • Connection Type: To determine whether the radio will obtain an IP address from a DHCP server on the connected network or whether a static IP address will be entered. Select the Static IP option for this point-to-point configuration.

     Since the Static IP option has been chosen, the following fields must also be entered.

   • IP Address: A valid IPv4 address for the network used must be entered in this field.

     • For the radio linked to the ground unit \(\Rightarrow\) 192.168.8.4 has been entered.

     • For the radio linked to the air unit \(\Rightarrow\) 192.168.8.5 has been entered.

   • Netmask: The Network Mask for the network must be entered. The default netmask 255.255.255.0 is normally left.

   • Default Gateway: If the radio is integrated into a network that has a defined gateway, then, as with other hosts on the network, the IP address of this gateway will be entered in this field.

     In case the user is using a PCS, 192.168.8.1 should be set here.

   • Default Route: This parameter allows the user to set this interface as the default route in the routing table.

     In cases where the LAN is the primary connection, this would be set to Yes.

   Important

   Once the IP Address has been changed, users will have to type the new address in the browser in order to continue with the configuration.

   

   LAN DHCP: A radio can be configured to provide Dynamic Host Control Protocol (DHCP) service to all connected devices (wired or wireless).

   

   LAN DHCP

   • DHCP Server: Enables/Disables the DHCP service for devices connected to the LAN port. Therefore, devices that are connected to the physical Ethernet LAN ports will be assigned an IP by the radio.

     Caution

     Before enabling this service, check that there are no other devices, either wired or wireless, with an active DHCP Server service.

     Hint

     At this point, if Enabled and if users have previously set the PC to the static IP address on the same subnet of the radio, they can now change the adapter settings back to “Obtain an IP address automatically”. Consequently, users will no longer have to change this setting on the PC every time they want to access the radio’s WebUI.

     

     Adapter settings - IP address automatically

   • Start IP Address: Select the starting DHCP address from which IP addresses will be assigned. The first octets of the subnet will be pre-set based on the LAN IP configuration, and cannot be changed.

     We enter here 192.168.8.100.

   • Number of Address: Set the maximum number of IP addresses that can be assigned by the radio.

     By default, 150 (this is an integer value).

   • Lease Time (in minutes): The DHCP lease time is the amount of time before a new request for a network address must be made to the DHCP Server. Defaults to 720 minutes.

3. Wireless \(\rightarrow\) RF: Allows to configure the radio module.

   Important

   Ensure that the RF Band, Channel Bandwidth and Frequency-Channel are set the same on each module.

   

   Wireless Configuration - Ground unit

   

   Wireless Configuration - Air unit

   RF Configuration:

   • Radio: Turns the radio module on/off.

   • RF Band: Select the desired RF band to work, 900 MHz or 2.4 GHz. In this case, we select 900 MHz.

   • Channel Bandwidth: Select the channel bandwidth from the list. Generally a larger channel has higher throughput, at the cost of sensitivity, while a smaller channel tends to be more robust, but at the cost of throughput. 1 MHz is recommended.

     Caution

     Refer to the radio specifications (Microhard documentation) in order to see the relationship and performance between channel bandwidth, throughput and sensitivity.

   • 900 MHz Channel: Set the Channel-Frequency. The frequency displayed is the center frequency and is available in 1 MHz increments. The values shown will vary with the Channel Bandwidth selected above.

     13-915 MHz is recommended.

     Important

     • This value must be the same on each unit in a network.

     • The noise floor of the specified channel will dramatically affect the link quality, it is essential to select the cleanest channel for superior performance.

   • Tx Power: This setting establishes the transmit power level that will be presented to the antenna connector of the radio. Select 30 dbm here.

     Caution

     For bench or proximity testing, it is best to use a lower power setting to avoid RF saturation.

   • Wireless Distance: This parameter allows users to set the expected distance the wireless signal should travel.

     The radio sets various internal timeouts to account for this travel time. Longer distances will require a higher setting, and shorter distances may work better if the setting is reduced. 3000 m is set.

   • Operation Mode: A radio in Master mode can provide a wireless data connection to multiple slaves/remotes. And, in Slave mode, it can maintain a wireless connection, i.e. to a Master.

     • For the radio linked to the ground unit \(\Rightarrow\) Master mode must be selected.

     • For the radio linked to the air unit \(\Rightarrow\) Slave mode must be selected.

   • TX Rate: This setting determines the type of modulation and, in turn, the rate at which the data will be transferred wirelessly. The default and recommended setting for both Master and Slave units is ‘Auto’.

     In ‘Auto’, the unit will transfer data at the highest possible rate depending on the receiving signal strength (RSSI).

   • Network ID: Each radio module network must have a unique Network ID. In this case, pDDL has been entered.

     Important

     This Network ID must be configured the same in each unit on the network.

   

   RF Serial Port Configuration:

   • Serial Port TX Rate: When using Ethernet and Serial data,

     • If the volume of serial data is high \(\Rightarrow\) Normal Rate (default option)

     • If the volume of Ethernet data is high \(\Rightarrow\) High Rate (compressed).

4. Serial \(\rightarrow\) Settings: This menu allows configuring the serial device server for the serial communications port. Data from the serial device can be brought into the IP network via TCP, UDP or multicast; it can also come out of the radio network on another radio serial port.

   

   Port Configuration:

   

   Port Configuration - Ground unit

   

   Port Configuration - Air unit

   • Port status: Select the operating state of the serial port. By default, Data.

   • Port Mode: RS232 must be selected.

   • Data Baud Rate: The serial baud rate is the rate at which the modem should communicate with the connected local asynchronous device.

     Important

     It must match the one configured in the 1x PDI Builder software \(\rightarrow\) 115200.

   • Data Format: This setting determines the format of the data on the serial port. It is the set of Data Bits, Parity and Stop Bits parameters.

     Important

     It must match those configured in the 1x PDI Builder software \(\rightarrow\) 8N1 (8 data bits, No parity, and 1 Stop bit).

   • Data Mode: This setting defines the framing of the serial output data.

     • In Transparent mode (default), the received data will exit the radio quickly.

     • In Seamless mode, the serial port server will add a gap between data frames to comply with a specified protocol.

     In this case, Transparent mode is selected.

   • Character Timeout: Defaults to 24 characters.

   • Maximum Packet Size: Defines the size of the buffer that the serial server will use to receive data from the serial port. When the server detects that the Character Timeout criterion has been met, or the buffer is full, it packs the received frame and transmits it.

     It must be 266, as this is the maximum packet size supported by Veronte Communication Protocol (VCP).

   • IP Protocol Config: This setting determines which protocol the serial server will use to transmit serial port data over the radio network.

     • For the radio linked to the ground unit \(\Rightarrow\) TCP Server.

     • For the radio linked to the air unit \(\Rightarrow\) TCP Client.

   

   TCP Configuration: The protocol selected in the IP Protocol Config field will determine which configuration options appear in this configuration menu.

   • In the TCP Server mode, the radio series will not initiate a session, but will wait for a Client to request a session. The unit will ‘listen’ on a specific TCP port.

     • If a session is established, data will flow from the Client to the Server, and, if present, from the Server to the Client.

     • If a session is not established, both Client serial data and Server serial data, if present, will be discarded.

     

     TCP Configuration - Ground unit

     • Server Mode: Monitor is recommended.

     • Local Listening port: The TCP port on which the server listens. Allows a TCP Client to create a TCP connection to transport data from the serial port. 20002 should be set.

     • Incoming Connection Timeout (seconds): Establishes when the TCP Server will terminate the TCP connection if the connection is in an idle state. It is recommended 5 seconds.

       

   • When TCP Client mode is selected and data is received on its serial port, the radio takes the initiative to find and connect to a remote TCP server. The TCP session is terminated by this same unit when the data exchange session is completed and the connection timeout has expired. If a TCP connection cannot be established, data is discarded from the serial port.

     

     TCP Configuration - Air unit

     • Remote Server IP Address: Enter an IP address of a TCP server which is ready to accept serial port data over a TCP connection. Users must set the IP adddress of the radio defined as Master, in this case, the IP address of the radio linked to the ground unit \(\Rightarrow\) 192.168.8.4.

Connection status radio

• Network \(\rightarrow\) Status: Provides an overview of the currently configured network interfaces, including the Connection Type (Static/DHCP), IP Address, Net Mask, Default Gateway, DNS, and IPv4 Routing Table.

  

• Wireless \(\rightarrow\) Status \(\rightarrow\) General Status: Shows the MAC address of the current radio, the Operating Mode (Master, Slave etc), the Network ID being used, Channel Bandwidth and Frequency information and the type of security used.

  

• Serial \(\rightarrow\) Status: This window displays a number of status items that help to visualize the operation, statistics and troubleshooting of the RS232 port.

  Note

  That is, the connection status with Veronte Autopilot 1x.

  • Port Status: Shows whether the RS232 port has been enabled in the configuration.

  • Baud Rate: The current baud rate used to interact with the connected device.

  • Connect As: This shows the type of IP Protocol Config chosen (TCP, UDP, SMTP, PPP, etc).

  • Connect Status: Shows if there is a current connection / if the port is active.

  • Receive bytes/packets

  • Transmit bytes/packets

    

In addition, to check the connection status between the Autopilot 1x and the radio, users can simply look at the LED indicators on the radio:

• When the TX LED turns red, that indicates that the modem is transmitting data over the radio.

• When the RX LED turns green, it indicates that the moden is synchronized and has received valid packets.

Paired radios

Once both radios are configured with these settings, they should be paired.

Therefore, by connecting both to the power supply, users can check that they are paired by simply observing the RSSI LEDs, they should be in a solid green. The more LEDs ilumitated \(\Rightarrow\) the stronger the link.

Moreover, users can access the radio’s WebUI to check it in the following menu:

Note

If they are correctly linked, by connecting only one of the radios to the PC, users will be able to access the WebUI of both radios.

Wireless \(\rightarrow\) Status: The Status window provides an overview of all wireless or radio settings and connections.

Wireless Status

• Traffic Status shows statistics on transmitted and received data.

• Connection Info displays information about all wireless connections.

  The MAC address, TX & RX Modulation, Signal to Noise ratio (SNR), Signal Strength (RSSI), and a graphical representation of the signal level or quality, as well as a RSSI Graph Link.

  By clicling on , a new window with the RSSI Graph Link will be displayed:

Basic radio configuration

Once the website has been accessed, follow the steps below which show the parameters that need to be modified for correct operation and pairing of the radios.

Note

This is an example of the radio configuration linked to a 1x air unit.

Note

After making changes to each window, it is important to click on “Save and apply”.

1. Basic Configuration.

   

   Basic configuration panel

   • Frequency (MHZ): This defines the frequency of the signal. There is a drop-down menu for frequency selection. We recommend 2220 MHz.

   Warning

   Be careful when choosing the frequency. The user may see interference with the Wifi frequency band, consult the radio spectrum.

   • Bandwith: This defines the RF bandwidth of the signal. Default value.

   • Network ID: Network ID allows for clusters of radios to operate in the same channel, but remain independent. A radio with a given Network ID will only communicate with other radios with the same Network ID.

   • Link Distance (meters): Set to an approximate maximum distance between any two nodes in meters. It is important to set the link distance to allow enough time for packets to propagate over the air. It is recommended to set the link distance 10-15% greater than the actual maximum distance.

   • Total Transmit Power (requested): This defines the total power of the signal (power is divided equally between the radio antenna ports). Set the appropriate power for each application. The power that has been set is small, as it is sufficient for our tests.

   • Routing Mode: As Large Network mode requires a license and is not available outside USA, we set Legacy mode.

2. Advanced configuration.

   

   Advanced configuration panel

   • Transmit/Receive Channels: Allows user to enable or disable each channel on the radio for TX/RX (each RF port is a channel). We have enabled both channels.

3. Networking. Multicast.

   

   Multicast panel

   • Default Multicast Algorithm: Broadcast.

   • Custom Pruning/Augmenting: Disable.

4. Serial/USB Setup

   

   RS-232 settings

   • Serial Port Setup: RS-232.

   • RS-232 Serial Port Settings

     • The value of the Baudrate, Data Bits, Parity and Stop Bits parameters must be the same as those configured in 1x PDI Builder.

     • Software Flow Control: Disable.

     • Transport Protocol: We recommend UDP. If no data loss can be tolerated, change this setting to TCP on the radio corresponding to the 1x air unit.

     • Peer IP: This should be the IP address of the radio on the other end of the RS-232. In this example, we must set the IP address of the radio linked to the ground unit.

Note

Both radios (the one connected to the GND unit and the one connected to the AIR unit) have the same configuration except for the Peer IP.

Peer IP in radio linked to the GND unit

In addition to these settings, different configurations can be stored in the same radio, on the Multi-Position Switch panel. The user can select the one that will work, with the radio’s switch position.

Multi-Position Switch panel

In this example only one configuration has been created.

With the above settings the configuration is finished. Furthermore, this configuration can be saved and downloaded in the Settings Profile window of the Configuration Profiles section.

Settings Profile panel

Before downloading the configuration, it is necessary to save it.

Save settings

Download settings

After configuring both radios with these settings they should be paired. Therefore, if we connect them to the power supply, when we switch them on, the LED will turn from fix red to fix green, this indicates that it is connected to at least one radio. Also, if we connect only one of them to the computer, we can access the StreamScape GUI of both.

And, in the Network Topology window of the Network Management section, we can see the link between them.

Connection between radios
