Installation guide

programmer interface, 3-pin port

The black 3-pin port is provided for personal computer programming of the unit. The unit can also be programmed

using the Bitwriter (p/n 998T). When using the optional PC Interface module, or hand-held programmer, it is

possible to configure any and all of the programmable functions as well as lock the Transmitter/Receiver and

System Features Learn Routines so that unauthorized users cannot change the configuration or program trans-

mitters to the unit.

When the learn routines have previously been programmed using an optional hand-held system programmer

(p/n 998T) or PC Interface module, they may have been locked. Before proceeding with reprogramming

the learn routines, they must be unlocked with either the 998T or the PC Interface module - this cannot be done

manually with the Valet switch.

______

This system can control two common power door lock types without any additional parts! With certain vehicles,

or if an actuator is to be installed, either a P/N 451M Door Lock Relay Satellite or two relays will be required.

IMPORTANT! If you mistake a Type C direct-wired system for a Type A positive-pulse system, the

module will be damaged!

The system can control this type of system directly, with no additional parts. The switch will have three wires on

it, and one will test (+)12V constantly. The others will alternately pulse (+)12V when the switch is pressed to

the lock or unlock position.

If you cannot get to the switch, and you find a set of wires that pulse (+)12V alternately on lock and unlock,

you must take care to ensure that it is not a Type C direct-wire system.

type A: (+) 12V pulses from the switch to the factory relays
