PC 6170 User's Manual
2.5
3 x Serial Ports
The PC 6170 provides three 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 8, ready to
accommodate a wide array of serial devices, such as fax modem,
scanner, serial mouse and touch screen...etc.
COM1 to COM4 are all D-SUB 9-pin connectors. To connect any
serial devices, 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, COM4 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;
1
2
3
4
6
7
8
2.6
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.
2.7
VGA
The PC 6170 has an analog RGB interface connector. It is able to
connect to an expansion CRT monitor, and the system can display
on both the flat panel and the CRT simultaneously.
