3 x Serial Ports
The PANEL PC 1150 provides four onboard serial ports installed on
the back bottom side of the chassis. For systems, COM1 and COM2
are RS-232 and COM4 is RS-232/422/485. Each serial port is with
+5V/+12V power capabilities on both Pin 1 and Pin 9, ready to
accommodate a wide array of serial devices, such as fax modem,
scanner, serial mouse and touch screen...etc. If the touch screen
option is included, its controller will share COM3.
COM1 to COM4 are all D-SUB 9-pin connectors. To attach to any
serial device, just plug in the device connector to the 9-pin D-SUB. In
terms of transmission distance, the RS-422/485 will perform better
than RS-232. In this case, COM2 is suggested to be set to
RS-422/485 and the related jumpers have to be set correctly first (see
the system board User's Manual). The RS-422/485 pin assignment is
listed as follows;

Parallel Port
The printer interface is a 25-pin D-SUB connector. To connect any
parallel device, just plug in the device connector to the 25-pin D-SUB.
