PowerStation Connectors
All XP PowerStations have the following connectors:
•
2 serial ports
•
2 USB ports for the keyboard and mouse

The XPx08, XPx10, and the XPx15 also have two PS/2 keyboard/mouse
ports. See the XP PowerStation CD for dimensional drawings and a diagram
to locate the components.
Serial Ports
The XP PowerStation has two serial ports that you can use to communicate
with external devices at baud rates of up to 115 Kbaud.
The COM1 port supports RS-232, while COM2 supports configurable RS-
232, RS-422, and RS-485 communication standards.
The communication standard you select for COM2 depends upon the
distance between the XP PowerStation and the controller, as well as the
communication standards that the controller supports. Use a standard DB9
connector for communicating with this port.
Note:
If you are using RS-232 communications, the length of the serial
cable should not exceed 50 feet (15 meters).
RS-422 and RS-485 communications offer greater noise immunity than
RS-232. These standards increase the maximum cable length to 4,000 feet
(1,200 meters).
RS-422 communications are full-duplex (send and receive simultaneously),
while RS-485 communications are half-duplex (send or receive).
For either configuration, be careful not to connect any wires to unused
connector pins.
