SYSTEM OVERHEATING
The MCD-4801 has an internal fan that will activate when internal temperatures increase. When
the temperature reaches 130
º
Fahrenheit (54
º Celsius)
, the terminal will shut off automatically. To
avoid this, move the MCD-4801 to shade and open up the case lid for venting.
WIRELESS ACCESS ISSUES
If you are unable to connect to the wireless access point, use an Ethernet cable to directly connect
to the system, and access the web interface screen (192.168.128.100). Click on
WLAN
to access
the wireless access parameters and configure to your required specifications (including WPA2
Security).
UNABLE TO CONNECT TO THE INTERNET
If you are able to connect to the wireless access point, but unable to connect to the Internet, it
could be:
1. The system has not yet acquired GPS. If this is the case, turn the system off and then back on.
Access the Web Interface screen to see the current status of the BGAN connection.
2. A BGAN satellite has not been found, normally because there is a line-of-sight obstacle like a
tree or building. Simply move the case to a new location and try again. Make sure to turn it off,
and back on when a new location is found. Make sure there are no items stored inside or on top
of the case that may be blocking the signal.
LOCATION AND LINE-OF-SIGHT
When choosing a place to set up your satellite equipment, please keep the following in mind:
First
, all satellite systems require constant line-of-sight access to the stationary satellite in the sky,
which means that you must choose your location with care. Small obstructions may sometimes be
ignored, but that is never guarantee of connectivity. Large obstructions – such as trees, buildings,
etc – must be avoided. The case requires a clear view of any of 3 BGAN satellites for operation.
Second
, there are other things that can obstruct your signal through radio-spectrum interference.
High voltage power lines may cause interference with the satellite signal, reducing performance or
preventing access altogether. Radar emitters, such as those found at airports, in police vehicles,
and in certain areas as part of speed enforcement measures, may also prevent the satellite
system from obtaining a signal lock. Further, radar installations can shut off an already
established satellite link by causing harmful interference.
Third
, it is wise to place the system high enough so that people who walk around the system will
not interfere with the signal. We recommend placing he case on top of a vehicle, or other high
location.
