7. Single Pilot AGC Standard 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 module to the desired pilot channel by downloading
the pilot channel program into the DSIM module's memory during
1.
Remove the RF module cover and install the DSIM-SS AGC module into the amplifier.
2.
If the outside temperatures are below 40ºF or above 80ºF, 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 40ºF and 80ºF then go to step 4.
3.
Using the table bellow adjust the RF output level at highest operating frequency by
pushing the "+" button to increase or the "-" button to decrease the RF output level.
Pressing the button once is used for small increments, holding the button down is for
large increments.
Below 0ºF
Between 40ºF & 0ºF
Between 40ºF & 80ºF
Between 80ºF & 100ºF
Above 100ºF
4.
If the DSIM-SS has a slope POT use it to set the inter-stage slope.
5.
Check and set desired amplifier levels.
6.
Re-install the RF module faceplate.
7.
Plug the controller cable into the DSIM and plug the controller into the cable.
8.
The controller LED will then flash red / blue rapidly while the DSIM controller and DSIM
module completes the syncing process. This process will take approximately
2-3 seconds to complete.
9.
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.
10. Press the 'Mode' once to go to MGC mode. Check that the output level and slope are
correct. Once level and slope are set, press "Mode" once to exit MGC (manual) mode.
