ETC ANRS485422

RS232 to RS485/422 Converter
Part no. ANRS485422
This bi-directional combined RS232 to RS485/422
converter is port-powered with an optional external
power supply terminal. An internal amplifier
supplies power from the RS232 port without
initializing the RS232 interface. If the RS232 port is
not capable of supplying sufficient power, the
external power supply can easily be connected. It
supports 2-wire RS485 and 4-wire RS422
communications of up to 300 - 115200bps. A
simple and reliable solution for most general and
industrial communication needs.
