The PC COM RS422/RS485
adapter
provides two asynchronous serial communication ports, which enables one
computer to communicate with other computers via communication lines,
or to link the computer and serial peripheral devices such as serial
printers, plotters, etc.
The PC COM RS422/RS485
board
can be installed in any IBM PC/XT, PC/AT, PC/386 or hardware compatible
system. To accommodate a variety of operating systems seven jumpers
permit maximum flexibility of configuration. You may select which
interrupt (IRQ2 - IRQ7), I/O address you desire.
The PC COM RS422/RS485 adapter provides signal drivers and receivers which can be set by software of hardware. Since the adapter support differential communication lines, it provides longer and more reliable communica-tion quality than does RS232. The communica-tion speed is up to 56K baud and the maximum transmission distance is up to 4000 ft.
Under the RS422 mode, RTS and CTS are used to provide communication flow control protocol. Under the RS485 mode, only trans-mission and receive signal are used, bothdrivers and receivers can be enabled or disabled by jumper setting or software. This means the RS485 provides a multi-point commu-nication protocol.
