Module Power and Miscellaneous I/O
Te s t P o i n t s
There are two test points associated with the CPM module. They are easily
read with a DC voltmeter by probing the PC board solder pads found in the
upper left hand corner of the module. The positive meter lead should be
connected to the pad while referencing the negative meter lead to the board
edge ground plane.
NOTE: Don't use the aluminum module enclosure as a reference as it has
an anodized surface with insulating properties.
The DC voltages shall be within the tolerance specified below. If not replace
the module.
TP1: + 5 volts DC ± 5%
TP2: +12 volts DC ± 5%
