DSIM-CG
Installation Guide Rev C
Instructions for Dual Pilot AGC
Operation
1.
Remove the RF module cover. If needed remove the 3 jumpers so the DSIM can be
installed. There is no need to adjust the slope or gain POTs, these will be controlled by the
DSIM after it is installed. Install the DSIM-CG AGC module into the amplifier. Then re-
install the RF module faceplate.
2.
Set the input levels to outside plant specifications with the input pad.
3.
Plug the controller into the DSIM-CG.
4.
The controller LED should be solid blue, indicating MGC-Gain Control Mode. If it is not solid
blue press the mode button several times until it is solid blue.
a.
Use the “+” and '-' button to set the output level at 750 MHz, or the highest
frequency to the correct output level.
5.
Press the mode button once to go to manual slope control mode. In this mode the
controller LED flashes purple every half second. Use this mode to set the amplifier low
frequency level using the + and minus buttons again. The level at 750MHz shouldn't
change more than 1dB. If it does, cycle back to manual gain control mode, by pressing the
mode button 3 times, to readjust the gain.
6.
From manual-slope control mode press the mode button once to start the align process.
a.
The align process takes 30 to 40 seconds.
b.
When done, the controller LED will flash blue every half second. This indicates that
the DSIM is in AGC mode and the setup is complete.
7.
Remove the controller from the cable and then the cable from the DSIM.
