Resetting IP Address & Terminal to Default/Reset Mode
If the unit should lockup or lose communication during the initialization
process, the unit remote interface can be reset using the supplied reset
mating connector. By installing the connector on J2 and cycling power, the
unit communication parameters will be reset to the factory test settings.
Refer to Section D for Quick Set-Up Guide.
3.3 OM20 Verification Testing
This Section assumes that the operator of the OM20 has sufficient knowledge of satellite system
operation to perform the verification tests. The use and/or tuning of the associated antenna
should be conducted in a safe manor and per the antenna manufactures guidelines. Precautions
should be taken as to not damage the OM20 and/or test/operational equipment that are connected
together. The brief testing described below is to verify the OM20 operation and does not
constitute operational testing over the Satellite. Refer to the Satellite Providers system
requirements and contact the Satellite Provider prior to radiating the system on any satellite.
Ensure that all operational parameters are correctly set to the system specification in the OM20.
Refer to
Section 4 of this document for further information on the OM20 Setup parameters.
3.3.1 TX Output Verification Test
Connect a Spectrum Analyzer to the TXRF output of the OM20. Verify that the modulator and
TX interface parameters of the OM20 are correctly set. Enable the modulator output. Verify that
the output frequency, symbol rate, and power level match the system setup parameters.
CAUTION
DC Voltage and/or High microwave energy may be present on the output
connector.
