To access the front panel communication options, perform the following
steps:
1. If the UPS is powered on, prepare your equipment for
shutdown.
Press and hold the Output Off button until the long beep
ceases (approximately three seconds).
Unplug the UPS. Wait until all indicators turn off and then
continue to the next step.
2. Plug in the UPS while pressing the Output Off button until
the alarm beeps. All indicators begin flashing.
3. Press and hold the Output Off button a second time until the
alarm beeps again.
A single indicator, corresponding with the current setting,
remains flashing.
4. Press the Output Off button to scroll through the
communication options, top to bottom. Each time you press the
button, the UPS beeps and the next indicator flashes.
NOTE If you do not save a selection within two minutes, the setup automatically
aborts and switches back to the original configuration.
5. Press and hold the Output On button until the alarm beeps to
select and save a communication option. Failure to release the
button immediately after the beep will cause the UPS to abort
the setup.
6. Press the Output On button again to return the UPS to
Normal mode.
NOTE Printer mode selections are the only serial communication modes available
from the front panel.
