DAC-2202 Antenna Control Unit Operation
2-7
In DVB Mode
Press
DOWN
or
ENTER
to access the
Sat ID Receiver Frequency entry mode.
The individual settings of the Satellite Identification tracking receiver and the current
signal level (AGC) will be displayed in each of the sub-menus below. To enable SCPC
mode you must first set the FEC parameter to “SCPC”.
In DVB Mode: FREQ #### AGC 1234
In SCPC Mode: MHz #### AGC 1234
To manually set, press the
LEFT
or
RIGHT
arrow key to bring the cursor up under the
character to the left, or right, of the decimal point respectively. 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.
If your ACU has an L-Band DVB receiver you will tune FREQ to 950-2150MHz. If
your ACU has an L-Band SCPC or NBIF receiver you will tune the MHZ to 950-
2150MHz (and then tune the KHZ value in the next step). If your ACU has a 70MHz
SCPC receiver you will tune the MHZ to 52-88MHz (and then tune the KHZ value in
the next step). If your ACU has a 140MHz SCPC receiver you will tune the MHZ to
104-176MHz (and then tune the KHZ value in the next step). Contact your dealer
and/or Service Provider for the correct tracking parameters.
If your system is configured to use an external AGC input, you must set
Frequency to 0000.
This will cause the ACU to read the input from the “AGC” &
“GND” terminal connections on the Terminal Mounting Strip Assembly.
Press ENTER to tune the receiver to this frequency and return to the frequency
display OR Press NEXT to abort and return to the main Satellite display.
FREQ 1100 AGC 1234
In SCPC Mode
MHz 1111 AGC 1234
In DVB Mode
Press DOWN or ENTER to access the Sat ID Receiver Baud entry mode. This is
used to input the numeric value of Baud Rate (symbol rate) OR of the KHz value of
the desired the
I ntermediate F requency (950-2150) you want to use for Tracking.
This setting of the Satellite Identification tracking receiver and the current signal level
(AGC) will be displayed.
In DVB Mode: BAUD 20000 AGC 1234
In SCPC Mode: KHz #### AGC 1234
To manually update, press the LEFT or RIGHT arrow key to bring the cursor up
under the character to the left, or right, of the decimal point respectively. 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.
DVB: Current receivers can be set to any desired Baud Rate between 3000 and
30000. It should be set to the symbol/baud rate of the digital carrier you chose to
use for tracking. This setting also changes the bandwidth of the receiver. Baud
setting of equal to or less than-5000 sets the receiver to 7.5 MHz bandwidth. A Baud
Rate of 5001 and greater sets the receiver bandwidth to 20MHz.
SCPC: Key in the desired KHz frequency value you wish to use for tracking.
Press ENTER to set the desired Baud/KHz and return to the Baud/KHz display OR
Press
NEXT
to abort and return to the main Satellite display.
Baud 20000 AGC 1234
In SCPC/NBIF Mode
KHz 0999 AGC 1234
Tone OFF AGC 1234
Press DOWN or ENTER to access the Tone sub-menu . This setting is used to turn
ON or OFF a continuous 22 KHz Tone output from the tracking receiver.
Press the
LEFT
or
RIGHT
arrow key to display a cursor underneath the current state.
Use the UP or DOWN arrow key to change states.
ON is used to select High Band frequencies and OFF is used to select Low Band
frequencies from the matrix switch.
Press ENTER to set the desired tone setting OR Press NEXT to abort and return to
the main Satellite display.
