T
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.
