USER MANUAL FOR RD-8132 3.1.2 REMOTE CONNECTION TO OMT If remote connection is needed, users can select [Remote connection via modem] in connection type window. Select desired serial port and click “OK” in [Serial Port Configuration] window to go to OMT main window and start modem initialization. Click “connect” and the [Remote Connection] window will show up.
USER MANUAL FOR RD-8132 3.3 RF PARAMETER It is recommended to configure the following RF parameters for the first installation. 3.3.1 SWITCH Switch is to enable/disable power for carrier1,carrier2, RF and self-oscillation. When user checks and sets non-RF parameters, such as checking physical antenna connection, switching off will disable equipment power temporarily to protect PA in operation.
USER MANUAL FOR RD-8132 Config: Enter the required value in setting columns and click [Config] button to finish the configuration operation. There are two methods to insert the channel number: z Insert the desired channel number (within the setting range) into the [Setting] column directly z Right click the [Setting] column, the [Frequency Calculator] dialogue window seen as below will popup, insert the desired channel number. Then the corresponding frequency will turn up automatically.
