OM20 Universal Outdoor Modem OM20 Initial ConfigurationTM116 – Rev. 1.2 3-4Resetting IP Address & Terminal to Default/Reset ModeIf the unit should lockup or lose communication during the initializationprocess, the unit remote interface can be reset using the supplied resetmating connector. By installing the connector on J2 and cycling power,the unit communication parameters will be reset to the factory testsettings. Refer to Section D for Quick Set-Up Guide.3.2 OM20 Verification TestingThis Section assumes that the operator of the OM20 has sufficient knowledge of satellite systemoperation to perform the verification tests. The use and/or tuning of the associated antennashould be conducted in a safe manor and per the antenna manufactures guidelines. Precautionsshould be taken as to not damage the OM20 and/or test/operational equipment that areconnected together. The brief testing described below is to verify the OM20 operation and doesnot constitute operational testing over the Satellite. Refer to the Satellite Providers systemrequirements 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.3.2.1 TX Output Verification TestConnect a Spectrum Analyzer to the TXRF output of the OM20. Verify that the modulator and TXinterface parameters of the OM20 are correctly set. Enable the modulator output. Verify that theoutput frequency, symbol rate, and power level match the system setup parameters.DC Voltage and/or High microwave energy may be present on the outputconnector.3.2.2 RX Input Verification TestConnect a Spectrum Analyzer and Bias-T to the RXRF L-Band Output of the LNB. Ensure thatthe Antenna is correctly tuned and that the carrier of interest is visible and that the frequency andpower level is correct. Verify that all the receive parameters of the OM20 are correct. Removethe LNB coax cable from the Bias-T and connect to the RX L-Band input port J7 on the OM20.Enable the correct DC Bias Voltage for the LNB from the OM20 Browser. Verify that the OM20receiver locks to the carrier of interest.
