Factory Default Settings
If you should need to reset the NPS 550 to factory default conditions, the
best way to do this is to use the TEST button. This procedure involves
switching the NPS 550 off and on. If you use an external power supply,
unplug the power cord to switch off the NPS 550, otherwise use the
printer’s power switch.
1. Switch off the NPS 550.
2. Press and hold the TEST button while you switch on the NPS 550.
Keep the TEST button pressed for at least 20 seconds until the
PACKET, PRINTER and STATUS indicators flash simultaneously
with one second intervals.
3. Release the TEST button and wait at least five seconds (five indica-
tor flashes).
4. Press and hold the TEST button for at least five seconds until the
STATUS indicator remains constantly lit.
5. Restart the NPS 550 (power-off/power-on).
The NPS 550 is now reset to factory default conditions.
Note: The Node and Internet Addresses (NODE_ADDR and INT_ADDR)
remain unchanged, but all other parameters are reset to factory default
values.
