Vehicular Repeater System
2. INTRODUCTION
The Futurecom MOBEXCOM DVRS® Vehicular Repeater is designed to interface to a range of mobile radios and
control heads. It permits expanded operation of portable radios. The Vehicular Repeater system consists of e.g. a MCS2000
mobile radio, MOBEXCOM DVRS® Vehicular Repeater unit, a mobile radio Control Head and a RF multiplexer. The
Control Head communicates with the Vehicular Repeater and the mobile using a serial data protocol.
REPEATER MODES
The Vehicular Repeater operates in one of three modes. The mode of operation is selectable from the Mobile Control
Head by the mobile radio operator.
The three modes are known as the MOBILE, LOCAL and SYSTEM modes. The function and purpose of each mode is
described as follows.
Mobile Mode
In the MOBILE mode, the vehicular repeater is completely disabled. The mobile radio is operational and will permit
the mobile radio user to communicate conventionally, using the mobile radio. The mobile user may select the desired
mobile operating channel, adjust the receiver volume level and transmit using the microphone Push-to-Talk (PTT).
This mode is used when Repeater operation is not desired. The Vehicular Repeater System operates similarly to a
standard mobile radio system, as if the Repeater were not present. The RF multiplexer is disabled and the antenna is
connected directly to the mobile radio.
The MOBILE mode should be selected if several Repeater equipped vehicles are in the same area and another
Vehicular Repeater already has LOCAL or SYSTEM mode enabled.
Local Repeat Mode
In the LOCAL repeat mode, the Vehicular Repeater is enabled to permit communications among nearby portable
radio users and the mobile radio user. Repeater signals are not retransmitted by the Mobile Radio, so that
communications on the mobile channel will not be disturbed. However, all functions of the mobile radio operate
normally, except for scan, microphone mobile Push-to-Talk, scan activation, mode selection, zone selection, home
channel operation and mobile channel selection. When the LOCAL repeat mode is selected, the mobile radio scan is
deactivated and the mobile radio reverts to the selected mobile channel. Signals received by the Vehicular Repeater
receiver are heard in the mobile speaker and will also be retransmitted by the Vehicular Repeater transmitter. Signals
received by the Mobile receiver are heard in the Mobile speaker and will be transmitted by the Vehicular Repeater.
When signals are present in both the Vehicular Repeater and Mobile receivers simultaneously, the signal from the
Vehicular Repeater will have priority in the mobile speaker. (Note that the receiver/PTT and speaker priorities are
programmable.)
The mobile user will key only the Vehicular Repeater transmitter when using the microphone Push-to-Talk. The
Vehicular Repeater receiver has full priority over the mobile radio operator microphone Push-to-Talk. To respond to a
mobile signal, the mobile operator must enter either the MOBILE or SYSTEM mode to be able to transmit from the
mobile radio.
The mobile user may adjust the receiver volume level and transmit over the Vehicular Repeater using the
microphone Push-to-Talk.
The LOCAL mode, as the name implies, permits communications among portable radio users and the mobile radio
operator, without interfering with the mobile radio dispatch channels.
System Repeat Mode
In the SYSTEM repeat mode, both the Mobile Radio and the Vehicular Repeater are enabled to permit the full
exchange of communications among nearby portable radio users, the mobile radio user and the dispatcher and other
users on the Mobile Radio channel. Signals received by the Vehicular Repeater receiver are heard in the mobile speaker
and will also be retransmitted by both the Vehicular Repeater and Mobile transmitters. Signals received by the Mobile
receiver are heard in the mobile radio speaker and are also retransmitted out of the Vehicular Repeater transmitter.
However, all functions of the mobile radio operate normally, except for scan, scan activation, mode selection, zone
selection, home channel operation and mobile channel selection. When the SYSTEM repeat mode is selected, the mobile
radio scan is deactivated and the mobile radio reverts to the selected mobile channel. When signals are present in both
the Vehicular Repeater and Mobile receivers simultaneously, the signal from the Vehicular Repeater will have priority in
the mobile speaker. (Note that the receiver/PTT and speaker priorities are programmable.)
Futurecom Systems Group Inc. 8A083X01_UHF.DOC Rev. Preliminary Page 6
Vehicular Repeater System
The mobile user simultaneously keys both the Mobile radio and Vehicular Repeater transmitters when using the
microphone Push-to-Talk. The Vehicular Repeater receiver has full priority over the mobile radio operator microphone
Push-to-Talk. The mobile radio operator microphone Push-to-Talk has priority over the Mobile receiver.
When signals are present in both the Vehicular Repeater and Mobile receivers simultaneously, the signal from the
Vehicular Repeater has priority in the mobile speaker.
The mobile user may adjust the receiver volume level and transmit over the Vehicular Repeater and Mobile Radio,
using the microphone Push-to-Talk.
The SYSTEM repeat mode is used when full communications among all radio parties is desired.
CONTROL HEAD
The control unit is e.g. the standard MCS2000 control head. The Vehicular Repeater is designed to operate with a variety
of control heads. It is a ruggedly constructed weatherized control unit, incorporating an array of pushbuttons, a Liquid
Crystal display, 2 knobs and 2 LED indicators. The display and pushbuttons are backlit for nighttimes visibility.
The control unit is housed in a two-piece plastic, weather-resistant housing. The external radio/repeater connections are
made to connector on the rear of the unit. A microphone is provided and is secured to the control unit connector on the front
of the control unit.
A serial-control data interface is used to provide a communications connection between the control unit, the Vehicular
Repeater and the mobile radio.

Vehicular Repeater System
REPEATER RADIO UNIT
The Repeater is designed to implement a Vehicular Repeater System, to provide portable radio users greater
communication range by repeating signals through the vehicle's mobile radio to the dispatch centre. Various modes of
repeater operation are available, to suit different operational requirements. The Vehicular Repeater Radio is the central
connection point for the vehicular system. It connects to an external Control Head and Mobile Radio.
It includes all the necessary hardware for repeater operations. The Repeater is housed in a weather resistant metal
enclosure with 2 removable covers. The covers provide protection for the connectors. The Repeater is mounted on a RF
multiplexer.
The Repeater communicates with the control head and the mobile radio via serial communication bus.
VHF MOBILE RADIO UNIT
The Mobile Radio used in the Vehicular Repeater System is e.g. a standard Motorola MCS2000 radio. Refer to Motorola
documentation for details of operation of this radio. The Vehicular Repeater is designed to operate with a variety of mobile
radio units.

3. OPERATION
CONTROL HEAD
The Repeater Control Head selects mode of operation for both the Repeater and the Mobile Radio.
To Turn the Repeater ON or OFF
Press the button in the Volume knob located on the left side of the control unit. The display should become active
when the system turns ON. A test message appears briefly on the display. When the system is turned ON, the Mobile
Channel and Repeater Mode will automatically return to the same settings that were in effect when the power was last
turned OFF. Press the button in the Volume knob second time to turn the Repeater OFF.
To Change the Speaker Volume
Turn the Volume knob until the desired volume level is reached.
To Change the Repeater Mode
Press the 'H/L' button once. The Repeater mode is changed in the following sequence: MOBILE-SYSTEM-
LOCAL-… In the Mobile mode the alphanumeric display shows ‘ZONE CHANNEL’. In the System mode the display
changes to ‘RSYS CHANNEL’ and in the Local mode it shows ‘RLOC CHANNEL’. (‘ZONE’ is the selected Mobile
zone name while ‘CHANNEL’ is the selected Mobile channel name.) When the LOCAL or SYSTEM repeat modes are
selected, the mobile radio scan is deactivated and the mobile radio reverts to the selected mobile channel.
NOTE
The Mobile zone and channel cannot be changed while in LOCAL and SYSTEM repeat
modes.
Refer to the earlier description of repeat modes.
MOBILE XMIT Status Indicator
The 'MOBILE XMIT' red LED indicator is one of two status indicators that is provided on the Control Head,
located in the upper left corner. This indicator will light whenever the Mobile Transmitter is keyed. This will occur in
'MOBILE' or 'SYSTEM' mode when the microphone Push-to-Talk is being pressed or when a signal from the Vehicular
Repeater is being retransmitted by the Mobile Radio (In 'SYSTEM' mode).
MOBILE BUSY Status Indicator
The 'MOBILE BUSY' orange LED indicator is one of two status indicators that are provided on the Control Head,
located in the upper left corner. This indicator will light whenever the Mobile Radio is receiving any signal on the
selected Mobile Channel. If CTCSS (Channel Guard) tone coding is used, the signal may not be audible if the coding
does not match.
Note that if the microphone is “off-hook”, the Mobile/Repeater audio will be heard on the speaker even if CTCSS is
not present or is incorrect. This is the same as the Monitor function.
ALPHANUMERIC Status Indication
The ‘ZONE’ is not displayed in the LOCAL and SYSTEM repeat modes. Instead, this portion of the alphanumeric
display shows the status of the Repeater in these two modes together with 'MOBILE XMIT' and 'MOBILE BUSY'
status indicators.
The following tables summarize indicators for different Repeater states:
