Originally available on the Motor-Power Interface Board and now integrated on the new
Motor-Power board, four connectors provide power and signal for fixed-range IR sensors.
A separate connector provides signal path for an additional four IR sensors.

LEGACY MOTOR-POWER
Figure 27. The Original P2 Motor-Power Board
The legacy Motor-Power
system is a two-board set that
connects the H8S controller’s
control signals to the original
P2 Motor-Power board, and
provides connections for
switched radio and auxiliary
power, power and digital
inputs for IRs, charge-
detection port, and
emergency stop detector.
See the H8S-controller board
in Appendix A for interface
connection specifications.
