Serial¶
Two serial interfaces are available with Veronte Autopilots, RS-232 and RS-485, and more can be added by using the Can Expander Board. Each one of the serial interfaces is associated with a set of pins, which are displayed when an interface is selected.
Connections – Serial
The following fields can be configured:
Baud rate: This field specifies how fast data is sent over a serial line.
Length: This field defines the number of data bits in each character.
Stop: Stop bits sent at the end of every character.
Parity: is a method of detecting errors in transmission. When parity is used with a serial port, an extra data bit is sent with each data character, arranged so that the number of 1 bits in each character, including the parity bit, is always odd or always even.
Type | Start | Data | Parity | Stop |
Bits | 1 | 4-8 | 1-2 | 1-2 |
Note
All these settings are already specified for a given device,therefore, Veronte should match with them in order to be able to communicate.
Compatibility table:
