To add a 120 Ω termination resistor, set switch 3 on the port’s
assigned DIP switch to ON; set switch 3 to OFF (the default setting) to
disable the termination resistor.
To set the pull-up/down resistors to 150 KΩ, set switches 1 and 2 on
the port’s assigned DIP switch to OFF. This is the default setting.
To set the pull-up/down resistors to 1 KΩ, set switches 1 and 2 on
the port’s assigned DIP switch to ON.

NOTE
Do not use the 1 KΩ setting while in RS-232 mode. Doing so will
degrade the RS
-232 signals and reduce the effective
communication distance.
Software Installation Information
For software installation, download the relative utilities from Moxa’s
website:

• Download the NPort Windows Driver Manager and install it as
the driver to run with Real COM mode of the NPort Series.
• Execute NPort Windows Driver Manager; then map the virtual
COM ports on your Windows platform.
• You may refer to the DB9 Male pin assignment section to loop
back pin 2 and pin 3 for the RS-232 interface to carry out a
self-test on the device.
• Use HyperTerminal or a similar program (you may download
Moxa’s program, called PComm Lite) to test whether the device
is good or not.
