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.

2. DSIM-CG AGC Module & DSIM Controller Overview
The Digital Station Intelligence Manager (DSIM) product line is the next generation of automatic
gain control modules that provides the outside plant maintenance team with station diagnostic tools
that are unprecedented in the industry. The DSIM-CG AGC module is agile that allows the program
settings to be modified at any time to change the pilot channel number and type from analog to
digital or to change the operational mode into the AGC or manual modes of operation. Having this
flexibility to reprogram the DSIM-CG modules is a huge cost savings when doing system pilot
channel modifications over the fixed AGC since only the program settings need to be changed
instead of having to change out the entire AGC fixed module.
The DSIM-CG module is programmed to operate as a dual pilot AGC. In the AGC mode the primary
pilot can be programmed to either analog or digital pilot signal from channels 52 to 142. The
secondary pilot can be ether analog or digital from channels 2 to 25. In AGC mode the DSIM-CG
remembers the output control values for operational temperatures, so if one of the pilots channels
are lost the DSIM-CG recalls what the control values are for the current temperature. The DSIM-
CG will operate on memory until both pilot channels have been restored. The DSIM-CG
incorporates a bi-colored blue and orange LED that indicates the different operational modes and
settings of the DSIM-CG during setup and operation.
The DSIM controller is used to set the DSIM-CG module’s pilot channel and to change into the
different operational modes during the amplifier setup. The bi-colored blue and red LED indicator's
blinking patterns will denote the current optional mode setting.

DSIM-CG
Installation Guide Rev C
The DSIM-CG modules has a default primary pilot channel 88 digital (609.00 MHz) and secondary
pilot channel 3 digital (63.00 MHz). The DSIM controller is used to set the DSIM-CG modules to
the customer selected pilot channel. In the setup of the DSIM-CG module the pilot channels that
are programmed into the controller are downloaded into the memory of the DSIM-CG module. The
pilot channel settings in the DSIM-CG module can be changed in the future by simply using a
controller programmed with the new desired pilot channels.
3. DSIM Mode Definitions
Operation Mode
Definition
MGC- Gain Control Mode
Gain Control Mode is for manually setting the inter-stage gain.
MGC- Slope Control Mode
Slope Control Mode is for manually setting the inter-stage slope.
AGC
In Automatic Gain Control (AGC) mode will make gain adjustments
to the station based on the level changes that occur on the pilots
channel.
TGC
Direct Thermal Gain Control (TGC) is not active for the DSIM-CG.
The DSIM-CG does have active thermal fall back, in case one or
both of the pilot are lost.
