16. Check the LED on the DSIM-GI Module to make sure the channel number is right. Refer to
section 10 for pilot channel blinking count overview.
17. Remove the controller THEN the cable from the amplifier and the DSIM-GI is all set.
9. Thermal AGC Setup
In setting up the DSIM-GI modules as a Thermal AGC the cable length dB values will need to be
adjusted to match the dB of cable that is in front of the station. The DSIM controllers will come
preset to have a default cable length setting of 27 dB in the memory. The controller is used to
set the DSIM-
GI module to either 9 dB, 18 dB, or 27 dB of cable by simply clicking the “Increase”
or “Decrease” buttons on the controller
.
1. Remove the RF module faceplate and install the DSIM-GI AGC module into the amplifier.
Then re-install the RF module faceplate.
2. For new amplifier installations allow the amplifier to warm up for a few minutes prior to
setting up the DSIM-GI AGC module.
3. Place the drive control select jumper to the manual position, then turn the manual gain
reserve pot fully clockwise. Measure and record the output levels at the highest operational
frequency. Next turn the manual gain reserve pot counter clockwise until the output levels
at the highest operational frequency are decreased by 5 dB.
4. Place the drive select jumper into the auto position.
5. Connect the DSIM controller to the DSIM-GI AGC module with the interface cable assembly.
6. The controller LED will then flash red / blue rapidly while the DSIM controller and DSIM-GI
module completes the syncing process. This process will take approximately
2-3 seconds to complete.
7. Once the controller LED stops flashing the red / blue sequence, it should then display a
constant blu
e, indicating that it is in MGC (manual) mode. Click “Mode” button twice to go
from MGC to TGC. The LED on the controller should now be a constant purple. Note if the
LED is flashing fast for the AGC channel count followed by an orange 1 or 2 blink, click the
"Mode" button once to change from AGC to TGC.
