Ethernet Link
If the Link LED is ON, the Ethernet physical connection is configured and working
properly. If the Link LED is OFF, then the Ethernet physical connection is not
working properly, which could be because the wrong type of cable was used or
there is a problem with the host or device Ethernet interface.
If connecting directly to the end-user PC, use the crossover Ethernet cable pro-
vided. If connecting to a router or switch, use a straight-through cable.
Ethernet Traffic
The Ethernet Traffic LED flashes whenever the link is transferring data.
Signal Level
State

Flashing
The MMT9000 has adequate signal level to support the radio link. As the signal
level increases, the flash rate increases. If possible, turn or move the antenna
slowly until the Signal Level LED flashes as fast as possible (i.e. turn panel
antenna, reposition magnetic mounted antennas).
Off
The MMT9000 does not have adequate signal level (<-86 dBm). Move and/or
turn the antenna until it begins flashing. If a permanently mounted mobile
antenna is being used, then the vehicle needs to move.
