Modbus signal types EXOL types EXOL signal types: R = Floating point number (Real) (-3.3E38 - 3.
RS422 is a full duplex communication, meaning that 4 connecting wires are required; 2 for sending (Tx+ and Tx-) and 2 for receiving (Rx+ and Rx-). Tx is used for sending and Rx for receiving, meaning the Tx in a unit must be connected to the Rx in another and vice versa. Pertaining to signal levels, etc., RS422 and RS485 are identical. In order to connect RS485 and RS422: Connect Tx+ to Rx+ and Tx- to Rx- on the RS422 unit.

BACnet signal types BACnet In order to communicate via BACnet, the protocol has to be changed either via Regio tool© or via the parameter list in the display. Once the protocol has been set to BACnet, it can only be switched back to EXOline and Modbus via the display.
