Introduction
The DD Lite Cog-4 version is a simple text overlay device that can count distances from a reel, display pages, and
observation data on screen. This device is menu driven and has help menus to guide users though setup screens. The
DD Lite allows for five title screens to be stored and displayed, twenty six observation codes, one always on line for
manhole information, and a comment line that can be configured to be on or off. The following manual will explain in
detail the usage and configuration of the DD Lite Cog-4.

F4 Set Encoder Options
Figure 12: Set Encoder Options
The Encoder Options menu allows the Counting Sense, Decimal Place, Units Label, Distance Pre-Set, Scale Factor, and
Calibration to be set. Use the up and down arrow keys to change values and the tab key to move between fields.
Set the counting Sense to Up to have the counter count up as the cable is pulled out. Set the counting sense to down to
have the counter count down as the counter is pulled out.
If more (or less) than one decimal place of precision is needed the decimal places option may be changed to 0, 1, 2, or 3
decimal places.
The units label may be changed to f or m for feet or meters.
The preset value allows the user to set a preset distance into the encoder. This distance will vary from camera to
camera. It also depends if the user measures from the center of the manhole or start of the pipe.
Scale factor allows the user to manually set how many units per count will be used. On a 10 count counter, the unit will
count .1 units per count. On a 20 count counter the system will count .05 units per count. The scale factor can also be
found by calibrating the encoder. Press F9 to calibrate the encoder.

To begin press enter to zero the encoder.
Figure 14: Calibrate Encoder -Enter Distance to Calibrate Over
Enter the distance of cable to calibrate the system with. Ten feet (or meters) is enough to provide an accurate count, but
longer distances can be used to create an even more accurate count.
Figure 15: Calibrate Encoder - Pull Cable
Pull the cable off of the reel for the set distance entered. Make sure that the cable has been measured accurately or it will
through the whole calibration off. Once the cable has been pulled press enter to close the calibration window.
Once all of the Encoder options have been set, Press enter to save and close. To cancel and close, press ESC.
