RUGGEDCOM RS910W
Installation Guide
d
The Common terminal is isolated. However, there is transient voltage protection circuitry between the Common terminal and chassis ground.
e
Cnnected internally.
f
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.
Section 4.4.2
Serial RS232/RS485/RS422 RJ45 Ports
The RS910W can be equipped with serial RS232/RS485/RS422 RJ45 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 User Guide for the RS910W.
The following is the pin-out description for the RS232/RS485/RS422 RJ45 ports:

Section 4.4.3
Serial RS232/RS485/RS422 Fiber Ports
The RS910W can be equipped with serial RS232/RS485/RS422 fiber 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 User Guide for the RS910W.
