INTRODUCTION
The 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.
