 Firmware Update
 Custom Configuration
5.2.1 Feature Upgrade
If the customer requires feature upgrades such as 8PSK, 16QAM or DVB-S2 operation, contact
the Radyne Corporation Sales Department for ordering information.
Once the customer has the Feature Upgrade Card, the following steps are performed:
1. Power off the unit.
2. Install the Feature Upgrade PCMCIA Card into J1.
3. Power on the unit.
4. Status messages will be displayed on the Front Panel. Additionally, the status messages
will be sent out to Terminal Interface, J5.
5. The Event LED (yellow) will flash while the feature upgrade is being added. The LED on
the back panel (LNB POWER) will also flash during the upgrade process.
6. If the upgrade was successful, the Remote LED (green) will flash and the LNB POWER
LED will illuminate without flashing. Proceed to Step 7. If an error is encountered, an
error code will be displayed on the display, the Fault LED (red) will flash, and the LNB
POWER LED will extinguish. In this case, the upgrade was not successful. If no LED
illuminates, the upgrade may not be compatible for the unit. Do not re-power the unit and
