SRM9000X8 800MHz SERVICE MANUAL

Warnings and Cautions

Compliance with RF Energy Exposure Standards: To minimise exposure to RF fields during equipment service and repair, the antenna terminal of the SRM9000 radio should be connected to a suitable non-radiating RF load when the transmitter is in use.

SRM9000 radio equipment is to be connected

with a 24-volt supply, an approved 24V/12V converter must be used. The supply must not be

taken from a 12V tap on the battery.

To avoid RF injury, do not touch the Antenna when the Transmitter is in use.

Double-fused 12V Supply Leads, Antenna cables and Speaker wiring is to be routed as far away

as possible from gas or fuel lines or any electronic control device. The radio transceiver and

antenna are to be mounted as far away as possible from these devices and their cabling.

Equipment is to be installed, by a competent person, in accordance with the requirements of

local radio communications authorities and/or Health and Safety regulations.

Post installation checks should be performed to ensure that there is no effect on the operation of

the vehicle’s electronics.

WARNING

only

to 12-volt negative earth systems. In vehicles

WARNING

Do not operate your radio, without a handsfree kit, whilst driving a vehicle.

WARNING

Do not operate your radio in an explosive atmosphere. Obey the “Turn Off Two-way Radios”

signs where these are posted, e.g. on a petrol station forecourt.

Caution

During disassembly and assembly, refer to Torque Settings in Section 1.6

Caution

Customer configuration files should be saved prior to any alignment adjustments.

Preparing the radio for alignment will erase from the radio all customer PMR configuration data

(channel, signalling information etc). The only data retained by the Alignment Tool is the factory

alignment data for the radio (DAC settings for Tx power, front-end tuning etc).

SRM9000X8 800MHz SERVICE MANUAL

1. INTRODUCTION

1.1 GENERAL

The SRM9000X8 800MHz mobile transceiver is designed for PMR operation in analog systems or P25 in digital systems.

The SRM9000X8 transceiver can be used with either the SRM9022 Graphics Display Handset or the SRM9030 System Level Remote Control Head with Alpha capability.

1.2 S

This manual provides technical specifications, description and servicing details for the SRM9000 mobile radio transceiver.

COPE

1.3 DESCRIPTION

The design concept utilises wide band techniq ue s fo r RF tr ansmit and receive circuitry with digital signal processing of analog or digital modulatio n a nd dem od ula tion. Electronic tuning is used throughout the mobile to eliminate manual tuning and level adjust ment.

A Digital Signal Processor (DSP) and a Programmable Gate Array (PLA) are used with other dedicated dev ices in the SRM9000 to perform the following fu nctions under software control:

• Frequency Synthesis of all operating frequencies.

• Modulation and demodulation of 12 . 5kHz o r 25 kHz FM signals or P25 digital modulation on a per

channel basis.

• Modem functionality for specified d ata modulation schemes.

• Filtering, pre-emphasis, de-emphasis, limi ting, compression, muting, CTCSS, Selcall or any other

frequency or level dependent signal modification.

• Serial communications with the Control Ancillaries and Alignment Tool. Tuning Control data for Tx and Rx.

•

The SRM9000 basic Transceiver comprises a rugged extruded aluminium sleeve, which houses a single printed circuit board assembly and provides all heatsink requirements. The sleeve housing is closed at each end by highimpact plastic end caps; all cable ports and mechanical interfaces are sealed against moisture and dust ingress.

The PCB assembly comprises a single, multi-layer PCB cont ain i ng all the RF and control circuitry. The PCB seats on an extruded aluminium tray that slides into the outer aluminium sleeve where it is secured with screws accessed from the outside of the case. Provision is made under the main PCB tray assembly for additional hardware options as well as optional a ccessor ies p l ug ged directly into the main PCB.

There are two installation methods available for the SRM9000. The outer aluminium extrusion has side flanges that allow the mobile to be bolted directly to any flat surface in the vehicle. A quick release cradle is also available.

Software Versions and Naming

There are various associated items of Software (SW) required for the SRM9000 radio and programmer to operate. This section simply defines the naming rules of the SW files to allow identification and conformity. This allows different versions of SW to be distributed and co-exist without confusion.

The SRM9000 Transceiver has three items of SW fo r digital and analog PMR, Trunking and Alignment. The 9022 Controller Mic/Handsets has one SW file for its PIC and the 9030 Control Head has two SW files for its

Flash and EEPROM.

1.4.1

Basically the Filename Structure is defined as follows:

• 2 character Applicatio n cod e

• 2 or 3 character SW Type code

• 3 character version number

• File Extension as required.

eg.

9ep_533.bin 9es_533.bin 9ecf101.hex 9ece101.hex

SRM9000X8 800MHz SERVICE MANUAL

1.4.4

This is a 3-digit number allocated by Engineering to identify the SW version. e.g. 103 = Version 1.03

1.4.5

The Programmer SW does not follow the above ru les as it is a PC based Program and its version number can be easily identified by starting th e SW . Later releases of SW will be backward compatible, unless deliberately not so, in which case a different directory structure/path may be implemented.

1.4.6

When a configuration is downloaded to the Transceiver, the Programmer performs a brief check on the SW currently installed in the radio. If a later version of SW exists (on PC hard-disk) then the Programmer will prompt the user with the following message :

NOTE. As early versions of FPP cannot recognise a more recent revision of the radio, it is important that the latest FPP version is downloaded from http://www.tmcradio.com.

SRM9000X8 800MHz SERVICE MANUAL

1.4.8

The SRM9000 Transceiver software is split into th e following separate modules:

When the Transceiver starts, it basically performs the following steps:

If the Mainline Software cannot be lo ad ed, or a Job file configuration has not been loaded (e.g. non-existent or checksum fail) then execution switche s to Backup Software until the error is corrected (e.g. by FPPing the radio).

There are three states that the radio can configure after switch-on:

Transceiver SW Description, Start-up and Backup-Software

• Bootloader and Backu p Software

• Start-Up Soft war e

• PLA and PLA-Backup Software

• Mainline PMR Software

• Initial execution starts with the Bootloader code, which attempts to load the Start-Up Software (if Start-

Up checksum is bad, then the Backup Software is lo ad ed .)

• Start-Up Software then do wnloads the PLA code (or PLA-Backup code if PLA checksum is bad) to the PLA device. If both PLA and PLA-Backup checksu ms are ba d then the radio is not operational and serial communication is not possible.

• Start-Up Soft war e then reads the On/Off switch plus Ignition-Sense lines and compares t he se with saved parameters to determine if the rad i o sho uld be continue to power-up or switch itself off again.

• Start-Up software t h en attempts to load PMR Mainline Software (dependent on save d pa ra meter) and switches execution to complete the powe r-up process and start normal operation.

• Mainline PMR Softw are (no rma l po wer-up) If the radio does not have a vali d Jo b file configuration loaded, then it will display a “No PMR Cfg”.

• Start-Up Software (characterised by “Alignment Mode” shown on the display). This is also t he cod e that is running when the radio is being aligned using the Alignment Tool.

• Backup Software (via various paths from above.)

1.4.9

A “WAILING SIREN” sound is emitte d from the Loudspeaker while the radio is running in Boot Backup Softw are . In this mode the FPP can be used to re-load a Jo bf ile, or re-load Start-Up or Mainline Operating Software.

Simply writing a Jobfile to the radio should allow the FPP to determine and update the offending software – however there may be instances where the FPP cannot determine this and the Start-Up and Mainline Software should be updated manually. This can be do ne using the FPP : Upgrade_Software : Get_File … then Download. Both Start-Up Software (filename = 9es_xxx.bin) and Mainline PMR (9ep_xxx.bin) should be loaded if the FPP cannot automatically fix the problem. The wailing siren s hould stop once the problem is fixed.

Note: Should these steps fail to restore the set and the Wailing Siren cease, the radio will need to be returned to

Wailing Siren (Boot-up Software Corrupted)

a Level 3 Service Centre for FLASH repl ace ment.

1.5 ADJUSTMENT AND ALIGNMENT

There are no manual internal adjustments in the SRM9000. Re-programming and alignment is done using software tools with the PCB installed in its chassis. For servicing, the radio PCB can be operated outside the chassis provided that a temporary heatsink is fitted under the transmitter PA module for transmitter servicing and that the receiver audio output be kept below 100mW for receiver servicing. Radio performance is only slightly affected by operating without the outer sleeve but there will be some change to performance when the metal cans are removed from the RF sections of the board.

On re-assembly, the PA module should be checked for a thin layer of heat-conducting paste. If this is missing or dried-out, it should be replaced prior to re-assembly.

HASSIS ASSEMBLY

Important Note!

1.6.1

Assembly of 'Chassis' (Inner Extrusion) to 'Outer Extrusion': 1.4 Nm (PA x 2), 1.25Nm (Others x 3) Assembly of 'Front' and 'Rear' end-caps to 'Outer Extrusion': 1.4 Nm.

1.6.2

Just enough thermal compound should be applied to the PA tray to provide good thermal contact with the chassis. Note. If thermal compound is old and difficult to spread, it should be discarded.

1.6.3

The Inner extrusion should initially be ne ste d t og et h er with the PCB and then the assembly slid into place within the outer extrusion.

Positioning the inner extrusion upwards by hand, it is then important to insert all screws by hand and ensure they have been fully inserted through the PCB, thereby locating the assembly correctly.

Whilst holding the inner extrusion upwards to ensure the assembly does not twist, lightly torque up the centre screw of the row of three followed by the PA module mounting screw towards the middle of the chassis.

The remaining screws can then be screwed up to full torque followed by re-torque of the first two screws.
