Comm. problem with cFP RS485 4 wire to Yokogawa UP150 RS485 2 wire

[Bruce]

cFP data sheet states that RS485 4 wire will not work with RS485 2 wire. I need to communicate with a bank of 6 Yokogawa UP150 temp controllers and 6 Overtemps, 2 wire system. I have seen some 4 to 2 wire converters on the web. I need to be able to use RS232 ports as well. I read a post about combining the 4 wire to 2 wire but it impacted the RS232 ports.

thanks

Bruce,

Here is a Knowledge Base on our website that talks about this very issue:

Hopefully this KB will address your question!
