RS-422 Full Duplex not working in Rx
On our Up Xtreme, we want to use the two COM connectors in RS-422 mode.
After configuring the BIOS and following the pinout found in the Quick Installation Guide:
We have managed to send some RS-422 Full Duplex frames using the TX- and TX+ pins but when receiving frames on RX- and RX+ there is only garbage received.
We have checked the signals with a scope, they are clean an the scope is able to correctly decode them in both directions.
@DCleri could you please confirm the pinout and that the RS-422 is functional in both directions with current BIOS?
Could we have the pinout of the DB9 connector on the chassis to confirm the correct wiring please.
