4.1. LEDs
The status LED visually show the current status of the radio.
Status LED (TX) This LED blinks red when the transmitter keys and is putting out
RF power. It blinks green upon the reception of data or RF carrier.
Power LED (PWR) This LED does a short blink, once every two seconds,
indicating to the user that the power to the modem is ON and the modem is
working. When the modem is in the command mode, this LED will blink on and off,
once per second.
When the GPS is trying to acquire satellite lock, the Status and Power LEDs will
alternately blink back and forth. This usually takes 10-20 seconds upon power-up
or loss of GPS satellite signal.
4.2. DC Power
DC power for the modem is connected to the 2-pin DC power input jack labeled DC
IN. Use the supplied cable to connect the DC power. The red wire is positive (+)
and the black wire is negative (-). Its connection is optional, as the user may
alternately apply power to Pin 9 and ground to pin 5 of the 9-pin I/O connector. If
the power cable run is over 3 feet long, Raveon recommends at least 18 AWG wire
be used.
The RV-M7 modem is supplied with a 6-foot DC power cable, Raveon part number
1C738-1.
Note: The RV-M7 has in internal 3-amp mini-fuse (automotive type) to protect it
and its power source against reverse voltage and serious hardware failures. In the
event it is blown due to a reverse voltage, it may be replaced by removing the
internal circuit board and replacing the fuse. This must be done by a qualified
electronic technician using ESD precautions.
