Interfacecom Co.,Ltd.
Overview and Applications
The Interfacecom RS232 To RS485 Converter allows RS-232 equipment to utilize RS-485 networks,
oper-ating in either point-to-point or multi-point, 2-or 4-wire. The RS232 To RS485 Converter is
one of the most cost effective RS-485 solutions on the market. Use with your standard PC or Laptop
to control RS-485 devices directly with no special software required. Any standard communications
software for your RS-232 serial ports will work. Plugs directly into standard DB9 male RS-232
port that comes with your PC or convert any number of your RS232 ports on a multiple port card
with DB9 connectors to RS-485. You can also make a RS-232 device a RS-485 device on a RS-485
network.
