Pinout Matrix

65JPC22-12CHB-E1

Part of the steering request when the encoder is rotated. It is a square wave signal identical to CHA-E1 but different phase. The TM uses the phase relationship of the two channels to determine whether CW or CCW steering is requested. The number of pulses is used to determine the total movement requested.

Moving: approx. 2.5V

Not Moving: <1V or 4.75V

Steering Encoder CM

66JPC22-13CHA-E2

Part of the steering request when the encoder is rotated. It is a square wave signal identical to CHB-E2 but different phase. The TM uses the phase relationship of the two channels to determine whether CW or CCW steering is requested. The number of pulses is used to determine the total movement requested.

Moving: approx. 2.5V

Not Moving: <1V or 4.75V

Steering Encoder CM

67JPC22-14CHB-E2

Part of the steering request when the encoder is rotated. It is a square wave signal identical to CHA-E2 but different phase. The TM uses the phase relationship of the two channels to determine whether CW or CCW steering is requested. The number of pulses is used to determine the total movement requested.

68JPC22-21B+EPO B+ provided through the normally closed EPO Switch (S21), when the Key Switch (S1) is closed, to the OTM cables, and to feed B+ to the K1, K2, and K3 relay coils. The status of the EPO switch is monitored by the CM and TM.

Moving: approx. 2.5V

Not Moving: <1V or 4.75V
