Table 28. Motor Temperature Sensors Connector (4-pos microfit)

PIN	SIGNAL	DESCRIPTION
1	Vcc	5 VDC
2	T2	To AN2-based temp sensor circuit
3	T1	To AN1-based temp sensor circuit
4	GND	Signal/power common

Otherwise, a jumper across R76 connects the AN1 port to the Fan Sensor system that is attached to the FET heat sink. Note, too, that with or without attachment of AN1 via R76, but with the heat sensor in place, a fan may be attached and activated whenever the motor-driver FETs get overheated, as implemented in all new AT systems.

Controller Power and Interface

Individual 26-pos IDC connectors and cables provide signal for the new H8S-based microcontroller or the legacy C166-based microcontrollers. A separate cable and connector provides for the H8S microcontroller and sonar power. Power and signal are shared on the C166 controller connector.

1	Vbat	Battery power
2	Gnd	Power common
3	Vcc	5 VDC for sonar
4	Vcc	5 VDC for sonar
5	nc	No connection

Radio, Auxiliary, and User Power Connectors

Various connectors provide conditioned 5 VDC @ 1.5A total and unconditioned battery power for the variety of accessories and custom user attachments. Some are AUX and RADIO power switched from the User Control Panel. And some are for Use the 12-position latchlock connector for legacy installations. Otherwise, screw-down auxiliary user-power connectors make custom attachments easy. Four-position microfit connectors also provide AUX power for standard accessories.
