Admin Connection Enabled check box.
10.10.1: Antenna Pointing Mode
Note: These instructions assume that the antenna being used requires manual pointing. If you
require instructions for a steerable antenna, please refer to BRM Support for Steered
Antennas .
By default, once the BRM is on, the BRM enters Antenna Pointing mode; it will be pointing to the
satellite the user chooses until they decides the signal strength is good enough to have a reliable
connection over the network.
If you open the Notifications page and select the
Signal Strength
option, you will find a good
way to check the quality of the signal strength.
Signal Quality
and
Signal Strength
are
displayed, followed by the corresponding bearer type.
Return to the Device page and note the following indications:
1. Verify the antenna pointing is enabled (should be enabled by default) by selecting Get_Antenna_
Mode.
> If enabled the response is
Success: {"enabled" :true}
> If not enabled the response is
Success: {"enabled" :false}
2. Is antenna pointing disabled?
> If Yes , enable it by checking the Antenna Pointing Enabled check box and selecting Set
Antenna Mode
> If No , proceed to Step 6
3. Select the Get Sat Table button which displays a list of satellite IDs with their current azimuth
and elevation, per
Figure 34
.

4. Note the ID of the Satellite with the highest elevation value, and enter that ID into the Set
Current Satellite field and select the Set Current Satellite button.
5. Manually point the antenna until a sustained optimal signal strength and quality is achieved (Signal
strength of 45dBHz or greater is usually sufficient for a data connection to be successfully
established). As signal strength improves, so does signal quality. Please refer to Signal Quality
Scores - BRM Implementation and Guidelines for Value Added Manufacturers
for more details.
