PCE-5124 User Manual 28
The PCE-5124 offers six serial ports. The user can use JSETCOM2 to
select among RS-232/422/485 modes for COM2. These ports can connect
to serial devices, such as a mouse or a printer, or to a communications
network.
The IRQ and address ranges for both ports are fixed. However, if you
want to disable the port or change these parameters later, you can do this
in the system BIOS setup.
Different devices implement the RS-232/422/485 standards in different
ways. If you are having problems with a serial device, be sure to check
the pin assignments for the connector.
Note There are two kinds of dual COM cable kits for
PCE-5124 COM port pin headers, if you need
to use more serial ports, you may purchase
them from Advantech.
