Installation Guide Rev F
8. Single Pilot AGC Setup
The DSIM controllers will come preset to have a desired pilot channel stored in the memory. The
controller is used to set the DSIM-MV module to the desired pilot channel by downloading the
pilot channel program into the DSIM-MV module's memory during setup.
1. Remove the RF module faceplate and install the DSIM-MV AGC module into the amplifier.
Then re-install the RF module faceplate.
2. For new amplifier installations allow the amplifier to warm up for TEN minutes prior to
setting up the DSIM-MV AGC module.
3. If the amplifier has a main gain reserve pot, turn until output levels are at max point.
Measure the highest channel level.
4. Back off main gain pot 4 dB @ 750MHz or 3 dB @ 547MHz.
5. Set the ALSC switch to on.
6. Connect the DSIM controller to the DSIM-MV AGC module with the interface cable
assembly
7. The controller LED will then flash red / blue rapidly while the DSIM controller and DSIM-MV
module completes the syncing process. This process will take approximately
2-3 seconds to complete.
8. Once the controller LED stops flashing the red / blue sequence, it should then display a
constant blue, indicating that it is in MGC (manual) mode. Note: If the controller LED is
flashing blue, it indicates that it is in AGC mode; click “Mode” button two times to go from
AGC mode to MGC Manual Mode. In addition, if the controller LED displays a constant
purple, it indicates that it is in TGC mode; click “Mode” button once to go from TGC to MGC
Manual Mode.
9. Set the level and slope of the amplifier to the design specifications with the input pad and
Equalizer.
10. If the outside temperatures are below 32ºF / 0ºC or above 104ºF / 40ºC, then the RF
levels will need to be adjusted to ensure that the full gain compensation range of the DSIM
will be available over the operational temperature range. If the outside temperatures are
between 32ºF / 0ºC and 104ºF / 40ºC then go to step 14.
