3 INTERNAL CIRCUIT BOARDS
3.1 Power Supply Board
The larger circuit board in the DCM-200 serves the dual purpose of acting as the
mounting platform for the GUTC board, as well as providing the regulated DC power
source for the GUTC and cellular radio module. Figure 3-1 illustrates the profile of the
original power supply board (stock number 1001-0302) made prior to 2006 along with
the major component elements. Following this is an electrical block diagram.
