This section details the specific developer's board settings for
the GM/GM 47R5/48 family. It is important that you verify these
settings before powering up the developer's board and module.
The following configurations should be considered the baseline
whenever attempting to resolve issues with the board or
module. Note that HW flow control is turned on.
Caution! Ensure the Rotary Switch has been set to 4 prior to powering on
the Developer's Board. Failure to do so may result in damage to the
module.
