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.

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.
