INTRODUCTION

he ST-865M3 SmarTrunk II Logic Board is a microprocessor based

radio trunking logic board designed for use with Motorola GP68 Radio. The

ST-865M3 implements SmarTrunk II, an efficient radio channel allocation proto-

col. The SmarTrunk II Logic Board controls all radio functions including channel

scan, PTT, and all transmit and receive audio. In combination with the ST-852M

SmarTrunk II Digital Trunking Controller, the Logic Board provides a complete

multi-channel digital access radio trunking system.

The ST-852M is the heart of the SmarTrunk II system. Programming and opera-

tion is performed by the System Operator/Manager. Many of the programmable

features of the ST-865M3 require information unique to a specific system. These

system specifics can only be obtained from the System Operator/Manager.

In addition to SmarTrunk II trunking operation, the ST-865M3 has a conventional

operating mode. This mode allows the radio to operate as a conventional two way

radio on the programmed radio channels. Conventional mode can be disabled by

the dealer.

The ST-865M3 offers the user the following features:

• Store and send dialing

• 10 number memory speed dial (user programmable)

• Last number re-dial

• Different ringing tones to distinguish the type of call

• Clear channel alerting tells subscriber when a channel is available

• Ten levels of priority call override

• Two trunking modes: radiotelephone and fleet dispatch

• Capability of operation on SmarTrunk and conventional non-trunked

radio channels

• Automatic acknowledgment eliminates wasted airtime

• Five digit security code for dealer programming

• Remote Radio-Kill to disable illegal and non-paying customers

This manual is presented in four sections:

• Section 1, Operation, describes operational features.

• Section 2, Operating Modes, describes the operating modes available in

a SmarTrunk II system.

• Section 3, Installation, provides instructions for programming of radio

frequencies and installation of the ST-865M3 logic board.

• Section 4, Logic Board Programming, provides the installing technician

instructions to configure the ST-865M3 by programming the resident

EEPROM.

Please read the entire manual before proceeding in order to take advantage of all

the advanced features.
