LED Display
The XPress RF Modem has 16 LEDs that display the status of the device.
Troubleshooting
No Power LED:
Check the power connections.
No Radio Link LED:
The radio is looking for its matched partner. If both units are powered up and the Power LEDs
are active they may be too far away to create the radio connection. Try other locations that may
have a less obstructed path or try to reorient the antennas.
Yagi-type antennas get their best range when they are both oriented to point directly at each
other with the antenna elements oriented in the same plane (e.g. vertically or horizontally).
Radio Link LED on but Quality Indicator is low:
The units may be too far away to create a good radio connection. Try other locations that may
have a less obstructed path or try to reorient the antennas.
No Ethernet Link LED:
Check your network connections.
Still not working?
If practical, temporarily use an Ethernet cable to see if the network is working over a wired con-
nection. If a wire does not work then the problem is with the network.
