TWS-434A and RWS-434

Howdy,
Can the TWS and RWS data lines (Pin-2 on both modules) be connected together (share a data line) if there is only power to ONE module at a time? I have only one data line to control both modules.

If I correct undestand, you try to use RX and TX modules on one node with one uC circuit for communicating with other nodes ?

Yes, this is correct. I am using a PIC processor and using only one data in/out line (GPIO) . But documentation that
I find is very limited on the input/output circuits of these modules. Thank you for your quick response. George

I think u can use line transreceiver ic for this /////////......
