Setting the value to “1” disables the transmit PWM voltage normally present onthe transmit IFL cable.The options file must be modified through the console port.To modify the options file through the console port complete the following procedure.WARNINGThe following section MUST be completed to ensure that damageis not done to the BUC and that console pointing mode workscorrectly.NOTEWhen the value is set to zero, DC voltage will be felt on thetransmit IFL cable at the BUC (Block Up-Converter) during thepointing process which could cause damage to the BUC andpotentially generate an unwanted carrier.1.
