The OM-CONV-SER is an RS-485
half-duplex to RS-232 converter. It
is powered from the computer’s
serial (COM) port so no external
power is required.
This unit is small in size, has a long
transmission distance, can handle
high data rates, is very stable in
performance and connects to a
standard DB9 serial (COM) port.
The converter can be used in a wide
range of applications including
industrial automatic control and
measuring systems and PLC
applications.
