INTRODUCTION
The Futurecom 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. a mobile radio, 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 at the same time 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 may also be retransmitted by both the Vehicular Repeater and Mobile transmitters at the same time. Signals received by the Mobile receiver are heard in the mobile radio speaker and are also retransmitted out of the Vehicular Repeater transmitter. When the SYSTEM repeat mode is selected, the mobile radio scan may be 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 Mobile Radio will have priority in the mobile speaker. The mobile user may simultaneously key both the Mobile radio and Vehicular Repeater transmitters when using the 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.
CONTROL HEAD
The control unit is a standard mobile radio 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 nighttime 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.

(Channel-Guard) tone coding.
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.
MOBILE RADIO UNIT
The Mobile Radio used in the Vehicular Repeater System is a standard mobile
radio. Refer to the mobile radio’s user manual for details of operation of
this radio. The Vehicular Repeater is designed to operate with a variety of
mobile radio units.
OPERATION
OPERATION

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 both the Repeater and the Mobile Radio may transmit at the same time. In the Local mode the display 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. -
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.
