Appendix B Pointing the Antenna through the Console Port
This section describes the procedure for pointing the antenna using console commands and a
digital voltmeter (DVM).
B.1 Performing Console Antenna Pointing
When using console pointing, the Rx and Tx cables from the Satellite Router can remain
connected to the LNB and BUC, respectively.
Pin 8 on the RJ-45 connector MUST be pinned to pin 8 on the DB-9 connector to read DVM
voltages from the serial port.
B.2 Modifying the Options File to Disable the Transmit PWM Voltage
The options file
must
contain the line “
options set ODU odu_disable_tx_pwm 1”
with the
value set to “1”. Setting the value to “1” disables the transmit PWM voltage normally present on
the 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.
WARNING
The following section MUST be completed to ensure that damage
is not done to the BUC and that console pointing mode works
correctly.
NOTE
When the value is set to zero, DC voltage will be felt on the
transmit IFL cable at the BUC (Block Up-Converter) during the
pointing process which could cause damage to the BUC and
potentially generate an unwanted carrier.
