Cautions

Installation of this equipment should only be undertaken by suitablytrained and authorized personnel.

The MRP2000 repeater operates from a DC power source between 12 and16volts.

NEVER connect to a power source of more than 16v DC. Voltage above 16volts DC will cause damage to the transceivers and repeater interfacecontroller.

DO NOT reverse the polarity of the power supply when connecting theMRP2000.

DO NOT operate the MRP2000 in extreme temperature ranges;below -10°C or above +60°C.

NEVER operate the MRP2000 without both antennas connected to the aerialports, as this will cause damage to the PA devices of the transceivers.

BEWARE The transceivers inside the MRP2000 may become hot.Care should be taken to not touch the transceiver casing if opening therepeater soon after use.

Introduction

This instruction manual details the installation and configuration of theMRP2000 mobile repeater unit.

The MRP2000 is a cross band repeater comprising three ICOM PMR mobiles(1 VHF and 2 UHF), two control heads and two fist microphones (for in-vehicleuse). The radio equipment, antenna duplexer and repeater control circuitryare housed in a lockable steel enclosure.

The MRP2000 mobile repeater has been designed to offer maximumcommunication flexibility.

It provides essential radio communication in several operational modes :

• between control room and ambulance crew whilst in the vehicle

• between control room and crew members when they are out of the vehicle

• between individual crew members when they are out of the vehicle.

For VHF operation the IC-F1010 model is used, for UHF 2 x IC-F2010.

The IC-F1010 VHF transceiver is a standard 25 Watt PMR mobile supportingmultiple signalling formats.

The two F2010 UHF transceivers are standard ICOM PMR mobiles, withmultiple signalling formats. One radio is configured to act as a receiver, theother as the transmitter. Transmit power is set to 2 Watts for extended talkthrough operation and lower current consumption.

Note : The transmit power output should not be changed.

Programming and configuration of the repeater is easily achieved using PCsoftware. Configuration data is transferred via the microphone sockets on theradio heads, there is no need to remove the radios from the enclosure.

A custom version of the CSF1000 PC programming package has beendesigned for the MRP2000.

The MRP2000 can be connected to a data system for which an externalconnector is provided. The input provides an option to SELCALL the UHFhand portable if a data message is received while the operator is away fromthe vehicle. The output provides the facility to send a message to the controlroom when the MRP2000 receives an emergency SELCALL from the UHFhand portable.


Programming

Repeater programming and configuration is carried out by the use of customPC software specially designed for the MRP2000. The MRP2000 should notbe programmed with the standard IC-F1010 / IC-F2010 programmingsoftware.

Programming interconnection leads are required (not supplied). These are thestandard OPC478 and OPC592 cables and provide connection between thePC and radio microphone socket.

Before programming can be carried out it is necessary to connect the remoteheads to the MRP2000 and install the ICOM CSF1000 programming softwareto a suitable PC. Please see Figure 4 (Connection and Installation section) forconnection information.

Computer requirements

Please note the Icom Programming software requires an IBM compatible PC486/Pentium CPU using any of the following operating systems ;

• MSDOS (version 4 or later)• Windows 3.x• Windows 95 or• Windows 98.

The programming software will not operate under Windows NT orWindows 2000.

Program Start Up

Ensure the software is correctly installed.Start the software by running the CSF1000.exe program.Select the serial port that will be used to program the radios (the setting forthis is found in the RS232 menu) and connect the leads between the PC andthe MRP2000.

The radios are pre-programmed with default data.

To prevent possible corruption or loss of essential operational information it isstrongly recommended that configuration data be read from the radios into thePC, edited as required and written back to the radio(s).

See the following notes for extra programming options.


UHF programming

The UHF radios are pre-programmed with default data.To ensure correct operation and power output it is stronglyrecommended that this data be read from the radio(s) into the PC, editedas required and written back to the radio(s).

Both UHF radios are programmed together, the custom software in the UHFreceiver controls most of the programmable functions for the repeater.

In the ‘Key and Display Assign’ screen (Figure 1 below) there are 2 specificfunctions for the programmable keys :

Special Function 1 UHF talk through control (UHF – UHF)Special Function 2 VHF talk through control (VHF – UHF)

Figure 1

These functions allow the operator to turn the talk-through facility ON or OFF.A short push of the radio function key turns the talk-through ON and a longpush turns the talk through OFF.

In the ‘RX Code CH’ screen (Figure 2) the ‘Auto TX Timer’ sets the talk-through time out limit from 01~255, these settings are in seconds ( 1 second ~4 minutes and 15 seconds maximum). Once the time out limit is reached, therepeater transmitter will drop and a double beep will sound, the UHF T/T Modeindication (see Figure 7) on the display will disappear. Talk-through may bere-initiated by the reception of a valid SELCALL or by use of the front panelbutton.A setting of 0 will disable the time out timer.


Also in the ‘RX Code CH’ screen (Figure 2) the first four decode positions areused to turn the talk through modes ON and OFF as follows:

RX CH 1 UHF talk through ENABLERX CH 2 UHF talk through DISABLERX CH 3 VHF talk through ENABLERX CH 4 VHF talk through DISABLERX CH 5 – 8 Unassigned (may be programmed as required)

Figure 2

Optional SELCALL Encode using the external I/O Port.

A SELCALL may be sent to a hand portable to notify the user that a messagehas been received on the data terminal. This is programmed by enabling a TXstation code in the ‘Memory Channel’ screen (Figure 3), the same TX code issent by using the Call key if programmed. (See page 10 EXTERNAL I/O).

Figure 3


Optional SELCALL Decode using the external I/O Port.

The data system can be notified by an emergency SELCALL received from ahand portable. This is programmed by enabling a ‘EXO’ option in the ‘RXCode CH’ screen. See Figure 4.

By switching the ‘EXO’ function to ‘ON’ the received SELCALL programmed inthe associated ‘CH No’ will activate the output.

Example

Figure 4 shows the received SELCALL, 55555 will activate the external outputline as ‘EXO’ = ‘ON’.

Figure 4


VHF programming

The VHF radio is pre-programmed with default data. It is preferable to readthis data into the PC, edit as required and write back to the radio.

The VHF radio may be programmed with the normal functions. The onlyadditional function that may be enabled (if required) is a decode position toenable a valid SELCALL to remotely turn the MRP2000 UHF-VHF talk-throughmode on.

By switching the EXO function to ‘ON’ the received SELCALL programmed inthe associated ‘CH No’ will turn the UHF – VHF function on.

Example

Figure 5 shows the received SELCALL, 11111 will activate UHF – VHF talkthrough as ‘EXO’ = ‘ON’.

Connection and Installation

Remote heads.

The two remote heads need to be connected to the separation cables asshown in fig 6 below, and the rear plates refitted.

Figure 6

DC supply.

The supplied DC cable needs to be installed in the vehicle and connectedbetween the MRP2000 and a fuse protected (20AMP rated fuserecommended) 13.8v DC supply.

Note: Also see caution section for more information.

Antennas.

Fit suitable VHF and UHF antennas to the vehicle. For optimum performanceof the radios allow as much separation between antennas as possible. Thedistance between antennas and MRP2000 should be no less than 1 metre.Close proximity of antennas may give rise to reception problems during talk-through operation. Consideration should also be given to potential problemswhich may be caused by siting antennas close to light-bars, etc.Connect antenna cables to the antenna ports.


Port 1

In the standard configuration of the MRP2000 this port is the VHF antennasocket.

Port 2

In the standard configuration of the MRP2000 this port is the UHF antennasocket.

EXTERNAL I/O (Configured at manufacture)

Input

The MRP2000 has one input which could be connected to a data system ifrequired. This facility could be used for informing a hand portable that amessage has arrived on the data terminal. There are two options for thisfunction which involves the modification of links on the repeater interface card.

• Option 1 : SELCALL message sent every time a datamessage is received

• Option 2 : SELCALL message sent only if MRP2000 is in talk-through mode.

Output

The MRP2000 has three outputs which may be connected to a data system ifrequired. This first output facility could be used to send an emergencymessage on the data system if an emergency SELCALL was received from aUHF hand portable. The next two outputs indicate the status of the repeaterwhether in talk-through mode, e.g. UHF-UHF; VHF-UHF.

These connections are available on the trailing lead which terminates in a6 pin Molex socket. See Figure 7 for connection details.

Figure 7


Front panel description

In the standard configuration of the MRP2000 two front panels are connectedvia separation leads. One front panel controls the VHF radio and the othercontrols the UHF radio(s). (Custom configurations may differ).

Depending on configuration the function display may show one of thefollowing:
