Building Additional Loopback Plugs
Loopback connectors are DB9 female serial port plugs,
with pins wired together as shown, that are used in
conjunction with the diagnostic software to test serial
ports. The RocketPort Serial Hub Si is shipped with a
a single loopback plug (RS-232/422).
This information can help you build additional plugs or
replace a missing loopback.
Wire the following pins together
for an RS-232 loopback plug:
• Pins 1 to 4 to 6
• Pins 2 to 3
• Pins 7 to 8
Note: The RS-232 loopback plug
also works for RS-422.
Wire the following pins together
for an RS-422 loopback plug:
• Pins 2 to 3
• Pins 7 to 8
