4.4.1
Serial RS232/RS485/RS422 DB9 Ports
The RUGGEDCOM RS910W can be equipped with serial RS232/RS485/RS422 DB9
ports. Each port can be set individually through the RUGGEDCOM ROS operating
system to operate in RS232, RS485 or RS422 mode. For more information, refer to
the RUGGEDCOM ROS Configuration Manual for the RUGGEDCOM RS910W.
The following is the pin-out description for the RS232/RS485/RS422 DB9 ports:

a
No internal termination is provided.
b
Connected internally.
c
The Common terminal is isolated. However, there is transient voltage protection circuitry between the
Common terminal and chassis ground.
d
Cnnected internally.
e
In RS232 mode, this pin enters a high impedance state. A DTE that asserts RTS will see CTS asserted,
although the device will not perform hardware flow control.
