The PCCOM ISA bus 2 port
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 terminals, modems, serial printers, plotters, ... etc.
ports, which
enables one computer to communicate with other computers via
communication lines, or to link the
computer and serial peripheral devices
such as terminals, modems, serial printers, plotters, ... etc. The PCCOM ISA bus 2 port
RS422/RS485 adapter may be configured with up to two individually
addressable RS422/485 ports and individually interruptible for any
PC/AT, PC/386, PC/486, Pentium or compatible system. It can be
addressed anywhere within the full range of PC I/O ports and each port
address can be set individually as your requirement. The interrupt
selection feature provides individual interrupt selection for each
port, so that you can arrange the 2 ports in any combination of
interrupt you need.
The PC COM ISA bus 2
port
RS422/RS485 adapter provides signal drivers and receivers, which can be
set by software or hardware. Since the adapter support differential
communication lines, it provides longer and more reliable communication
quality than does RS232. The communication speed is up to 460K 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 he
RS485 mode, only transmission and receive signal are used, both drivers
and receivers can be enabled or disabled by jumper setting or software.
This means the RS485 provides a multi-point communication protocol.
The PCCOM ISA bus 2 port
RS422/RS485 board can be used to plug in 8250, 16450, 16550, or 16650
chips, and the PCCOM device driver can detect it automatically. There
are two kinds of communication speed can be choose, one is normal speed
mode that its baud rate up to 115200, another is high speed mode that
its baud rate up to 460K.
When set the PCCOM board
to
RS422 mode, it is particularly suited to facilitate the connection of
terminals (VDUs) in multi-user operating systems.
