4-WIRE RS-485/422 TO 2-WIRE RS-485 ADAPTER
The AC38 may be used to convert RS-422 signals to RS-485. Many RS-422 communication ports do not have the ability to enable and
disable the drivers used to transmit data and therefore cannot be used on a two-wire network. (The Remote I/O Bus is a two-wire
communications network) The host RS-485 port of the AC38 may be used with either 4-wire or 2-wire communication lines. The AC38 will
transfer data to and from the 2-wire network on the Remote port while maintaining electrical isolation from the host link.
