FEC AUTO AGC 1234
Press DOWN or ENTER to access the FEC sub-menu. Select the Forward
Error Correction rate of the desired tracking signal. 1/2, 2/3, 3/4, 5/6, 6/7,
7/8 , AUTO or SCPC. AUTO automatically scans through all the standard
DVB & DSS FEC rates.
NOTE: When SCPC is selected, the FREQ parameter changes to read MHz
and the BAUD parameter changes to read KHz.
Continue pressing the UP/DOWN arrow key to toggle through the available
forced * (star’ed) FEC rates. If the satellite does not generate an NID but
does have a unique combination of FREQ, BAUD and FEC lock, select the
appropriate FEC* choice from this list. The ACU will then generate its own
unique forced NID (FFFE for DSS signals or FFFD for DVB signals) to
represent the desired satellite. You will need to enter this pseudo NID in
the NID setting below.
FEC MUST be set to SCPC if you have any one of the SCPC narrow band
receivers installed in your ACU (L-Band SCPC, 70MHz SCPC or 140MHZ
SCPC).
To manually update, press the LEFT or RIGHT arrow key to bring the cursor
up under the current setting. Use the UP or DOWN arrow keys to scroll
through the available FEC selections.
Press ENTER to set the desired selection OR Press NEXT to abort and
return to the main Satellite display.
NID 0000 AGC 1234
Press DOWN or ENTER to access the NID sub-menu. This setting, a four
digit HEX value with a valid range of 0000-FFFF, is based on the desired
received transponders’ Network ID (NID). If this parameter is provided in
decimal format, it will have to be converted to hexadecimal for entry.
Set the NID value to 0000 if;
• The signal you intend to track does not contain a valid NID.
• You do not want to use satellite identification function.
• You are using an external AGC input source which has been
provided to you in your system configuration.
• You are experiencing a hardware/software issue which is
preventing the ACU from decoding the NID and you want to
temporarily disable this function.
To manually update, press the LEFT or RIGHT arrow key to bring the cursor
up under a character. Continue to move the cursor until the desired
character to be edited is underscored (selected). Use the UP or DOWN
arrow keys to increment or decrement the selected character.
Press ENTER to set the desired NID OR Press NEXT to abort and return
to the main Satellite display.
