This bi-directional RS232 to RS422 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 4-wire
RS422 communications of up to 300 - 115200bps
in full-duplex. A simple and reliable solution for
most general and industrial communication needs.
