RS232¶
Point to point¶
This connection is recommended to establish with the computer while 1x is commanding via CAN to Veronte MC110 or Veronte MC24, since the USB connection between the PC and the 1x may be lost.
Note
Transmitter pin (TX) of one device is connected to the receiver pin (RX) of the other one, and vice versa.
RS485/422¶
Point to point¶
This connection is recommended to establish with the computer while 1x is commanding via CAN to Veronte MC110 or Veronte MC24, since the USB connection between the PC and the 1x may be lost.
Note
Output pin (OUT) of one device is connected to the input pin (IN) of the other one.
Inverted signals (N) are connected each other; in the same way non-inverted signals (P) are linked each other.
Daisy chain¶
This section details the technical considerations that must be taken into account when connecting the Autopilot 1x to a chain of devices via RS485/422.
Full duplex¶
Autopilot 1x includes an internal resistor of 120 \(\Omega\). A second resistor is required at the end of the line (again 120 \(\Omega\)) to allow the connection of multiple devices to the same line. This resistor may be placed on cable or PCB.
Full Duplex allows devices on an RS485 network to transmit and receive data simultaneously, enabling continuous bidirectional communication. This mode uses four wires, two for sending and two for receiving, which facilitates faster and more efficient data transfer.
The following diagram shows how to connect the devices:
Half duplex¶
Half Duplex allows devices on an RS485 network to transmit and receive data, but not at the same time. In this mode, communication alternates between sending and receiving, using only two wires for both directions.
The following diagram shows how to connect the devices:
Warning
The following mode of connection should be avoided.
CAN¶
Electrical diagram of CAN bus¶
Autopilot 1x includes an internal resistor of 120 \(\Omega\). A second resistor is required at the end of the line (again 120 \(\Omega\)) to allow the connection of multiple CAN Bus devices to the same line. This resistor may be placed on cable or PCB.
Point to point¶
Note
The user has the option to configure either of the two available CAN BUS lines on the Autopilot 1x: CAN A or CAN B.
The following sections detail the technical considerations to be taken into account when connecting the Autopilot 1x to a chain of devices via CAN.
Daisy chain¶
The daisy chain connection is the most common and recommended method for interconnecting multiple devices in a CAN system. This procedure involves sequentially connecting the CAN cable from one device to the next, ensuring that the total cable length is minimized to optimize network performance and reduce potential interference.
The following diagram illustrates an example of how to connect devices using this method:
Important
A resistor has been included in the diagram, which allows the connection of more devices, as explained in the Electrical diagram of CAN bus section.
Note
The standard designation for CAN lines in devices is typically CAN H (High) and CAN L (Low). These designations correspond to those of the Autopilot 1x, where CAN P (Positive) and CAN N (Negative) represent the High and Low lines, respectively.
Note
The user has the option to configure either of the two available CAN BUS lines on the Autopilot 1x: CAN A or CAN B.
Backbone with stubs¶
Another method for connecting devices via CAN is to use a master cable from which the necessary stubs will be made to connect the devices. This connection method allows the creation of stubs from the master cable to integrate each device into the CAN network.
It is important for the user to note that when connecting devices in this topology, the total length of the CAN BUS cable is limited. Exceeding this length may adversaly affect network performance and communication integrity.
The following diagram illustrates an example of how to connect devices using this method:
Important
To create stub branches from the master line, T-connectors or CAN splitter are required.
These connectors enable the connection of a device while allowing the main BUS line to continue, facilitating the connection of additional devices.
The CAN protocol specifications limit the distance a device can be placed from the BUS. The following table shows the distance limitations to be considered when setting up the system.
Bus Speed |
Bus length |
Stub length |
Node distance |
---|---|---|---|
1 Mbit/Sec |
40 meters |
0.3 meters |
40 meters |
500 kbits/Sec |

500 meters |
0.3 meters |
500 meters |
50 kbits/Sec |
1000 meters |

1000 meters |
Warning
If a cable stub (un-terminated cable) or a T-connector is used to connect to the bus line, then the stub distance should not exceed 0.3 meters.
Serial to Ethernet Converter¶
This section provides the process to follow to integrate a Serial to Ethernet Converter, with Veronte Autopilot 1x. In this example, WIZ108SR and WIZ107SR converters are used.
These protocol converters transmit the data sent by serial equipment as UDP data type, and converts back the UDP data received through the network into serial data to transmit back to the equipment.
WIZ107SR connection diagram:
Important
To ensure correct operation of the device, use an external power supply and not to connect it to the 3.3 line of Autopilot 1x.
Please note that it shares signal ground with Autopilot 1x.

Note
This integration is done for the WIZ108SR, this is for a connection via RS485 with Autopilot 1x. However, the process for the WIZ107SR device is almost the same.
Once the hardware installation is complete, follow the steps below to properly configure the connection and ensure stable communication between the devices.
Ethernet Connection in Windows¶
First, make sure computer is set to static IP address on same subnet as radio. The following substeps clarify how to set the IP address:
Connect the Ethernet cable of the WIZNet adapter, powered by 3.3V, to the Ethernet port of the PC.
Open Network and Sharing Centre menu and click Change adapter settings.
Select Local Area Connection, right click, and select Properties.
Select IPv4 and click Properties.
Set IP address to 192.168.11.X (in this example
192.168.11.8
is entered) and Subnet mask to255.255.255.0
. Click OK.
WIZNet software configuration¶
Open the WIZNet Software and select the Ethernet port with the IP assigned before in the dropdown menu.
Click on the Device Search option to scan for the device.
Then, if the module is properly connected to the network, it will appear in the search list. Select the WIZ108SR device to access its configuration.
Caution
If the module does not appear in the list and it has been previously connected to another PC, reboot the module (simply unpower it and power it up again).
This is because when the WIZ108SR module establishes a connection to a PC’s MAC address, it will only communicate with that PC unless it is rebooted.
The configuration must be as follows:
In the Basic Settings tab, make sure that the Network Settings parameters are:
Local IP:
192.168.11.2
Subnet Mask:
255.255.255.0
Gateway:
192.168.11.1
In the Channel #0 tab:
Change the Operation mode to UDP.
Set the Local port to
5001
(for example).Set the Remote host to the adapter IP previously configured in step 5 and a Remote Port, in this example port
5002
has been chosen.The Serial options must match those of the Autopilot 1x, so set them as follows:
Baud rate:
115200
Data bit:
8
Parity:
NONE
Stop bit:
1
Modify in the Serial data packing condition the size to
255
to send the data in 255 byte packets, so that each send will have more data.
Finally, click Apply Settings to save the configuration to the device.
Veronte Link configuration¶
Add a new UDP connection in Veronte Link and configure it with the same IP address and port as previously set in the Remote options of the WIZNet settings.
In this example:
Address:
192.168.11.1
Port:
5002
For more information on Veronte Link connections, please refer to the UDP connection - Integration examples section of the Veronte Link user manual.
1x PDI Builder configuration¶
Go to Input/Output menu \(\rightarrow\) I/O Setup panel.
Bidirectionally connect the RS485 Producer to a Commgr port Consumer, in this example it has been linked to Commgr port 3. Then, the same Commgr port Producer, in this case Commgr port 3, should be automatically connected to the RS485 Consumer:
Note
If the WIZ107SR module is used, i.e. a connection is established via RS232, bidirectionally connect the RS232 port to a Commgr port and not the RS485 port.
Go to Input/Output menu \(\rightarrow\) Serial panel \(\rightarrow\) RS485 tab.
Note
If using the WIZ107SR module, check the RS232 parameters instead.
Make sure that these parameters are the same as the parameter values previously set in the WIZNet software.
Baudrate: 115200
Length: 8
Stop: 1
Parity: Disabled
Following these steps, Autopilot 1x should appear in Veronte Link as follows:
