Yes, RS-422 devices can be connected to the CloudGate using the industrial serial card (CG1102).
RS-422 uses the same electrical signaling as RS-485 but operates in full-duplex (bidirectional) mode. The CG1102 card supports this, but it requires specific configuration:
The serial port driver must be explicitly set to duplex mode using appropriate commands.
The hardware switch on the card must be set to the 4-wire position to enable RS-422 operation.
Using RS-422 in LuvitRED
In LuvitRED, you can enable RS-422 support by selecting the "industrial serial duplex" option in the Serial In and Serial Out nodes. This setting automatically configures the port for full-duplex operation.
Flow Control Considerations
Please note:
CTS/RTS (hardware flow control) is not supported on the CG1102.
To prevent buffer overruns, you must use XON/XOFF (software flow control) when operating in RS-422 mode.
