GM49791-1 Circuit Board. This is the communication
module for all models and includes the gauge driver
provision needed to drive the oil pressure and water
temperature gauges for some models (requires
application software version 1.23 or later). See
Figure 8-44.
GM49791-2 Circuit Board. This is the interface circuit
board with the gauge drivers required on the
450/500REOZVB models only. For communication
purposes replace GM49791-2 with GM49791-1.
GM49791-2 is mounted in the communication module
location but does not provide the communication
function. See Figure 8-45.
8.19.2 Circuit Boards Views
Figure 8-43, Figure 8-44, and Figure 8-45 show the
differences between the communication circuit boards
and the interface circuit board with gauge drivers. The
SW2 DIP switches should be set to the open position
unless the instructions supplied with the kit indicate
another configuration.
