Can a transport wr21 talk serial Modbus RTU binary?

[The_James]

I have a transport wr21 and a device that communicates using a serial port Modbus RTU Binary protocol (Allen Bradley Prosoft). Can I and how do I configure the serial port to talk with it? The only think I have found to point me in this direction is the Legacy Protocols > Modbus Gateway > Modbus 0.

This will not enable me to set Async Port: 502 (defaults to 246)
There is no specification of RTU Binary for the port

This transport does not require a distinction between modbus ASCII and RTU. It treats it the same. So following page 563 of the manual and setting your desire port numbers should work.
