Rackmount DVRS Overview

• The Digital Vehicular Repeater System (DVRS) is typically mounted inside the trunk of a car and powered by the car battery.
• Some applications other than vehicular use require added flexibility that can be achieved with the use of a Rackmount DVRS that is designed to fit into a standard 19 in. rack.
• NOTE: Product Safety and RF Energy Exposure Booklet for Digital Vehicular Repeater Systems includes approved antennas and associated output powers for DVRS.
• The Rackmount DVRS is a Mobile Radio, Control Head, DVR-LX, and Filters packaged in a compact 19 in. rack tray as shown in Figure 1: Rackmount DVRS Form Factor.
• Dimensions of the Rackmount DVRS are 10½ in. x 19 in. x 15¾ in. (Height x Width x Depth).
• The Rackmount DVRS can be powered up by connecting it directly to a +13.8 VDC Power Supply.

• Program the MSU, DVR-LX®, and portables for DVRS operation.
• a. To program the DVR-LX, connect a PC with compatible Futurecom Repeater Configurator (FRC) programming software to the USB port located on the front panel of the Rackmount DVRS.
• b. Ensure that the templates are fully matched by following the guidelines provided in the Vehicular Repeater Programming Guide.
• c. Set DVR Tx Power to 32.5 dBm to provide the correct input signal level to the 50 W Power Amplifier.
• CAUTION: DVR Tx Power should not be set to more than 33 dBm or 2 Watts. Programming higher power levels may result in the Power Amplifier damage.
• IMPORTANT: When programming the DVRS frequencies, ensure that they match the DVRS filtering frequencies. To check the tuned frequency setting of the DVRS duplexer, refer to the DVRS labels located on the tray.
• Install the MSU Microphone.
• Result: Rackmount DVRS is completely installed.

Programming the External Alarm Option

If the optional External Alarm is installed in the Rackmount, it can be programmed with Futurecom Repeater Configurator (FRC). The External Alarm is triggered when specified repeater temperature or power output thresholds are crossed.

Figure 15: External Alarm Hardware Location

NOTE: By default, the alarm circuit is closed. When the alarm is triggered, the circuit opens.

Procedure:

1. Connect the repeater programming USB cable to the Rackmount and launch Futurecom Repeater Configurator (FRC) Software on a connected PC.
2. Load data from the APX repeater to the FRC and select Hardware Setup in the FRC navigation tree.
   • Figure 16: Hardware Setup in FRC Navigation Tree
   • The Hardware Setup window opens.
3. In the Relay Use, set Relay 3 to External Alarm.

4. Set the Temperature Alarm and Output Power Alarm to desired values.
   • Figure 18: Alarm Threshold Values
5. Save changes to the APX Repeater and restart the repeater.

Rackmount DVRS Antenna Requirements

• Any DVRS Model requires the use of two or three antennas, with one or two antennas connected to the Mobile Radio and the remaining antenna connected to the DVR-LX.
• The antennas are not part of the Rackmount package and need to be provided separately.
• IMPORTANT: All DVRS models require 30 dB minimum Antenna Isolation between the DVR and Mobile Radio Antennas for interference-free operation. A separation of several feet between the antennas may be needed to achieve this.
• In addition to 30 dB isolation, ensure that the RF exposure separation distance is maintained. See RF Energy Exposure Compliance, Awareness, and Control Information and Operational Instructions.

RF Energy Exposure Compliance, Awareness, and Control Information and Operational Instructions

• This radio equipment is intended for use in occupational/controlled conditions, where users have full knowledge of their exposure and can exercise control over their exposure to meet FCC limits.
• This radio device is NOT authorized for the general population, consumer, or any other use.
• CAUTION: Changes or modifications not expressly approved by Futurecom Systems Group, ULC. and Motorola Solutions could void the User’s authority to operate the equipment.

Temporary-Fixed Site

Futurecom and Motorola Solutions require the P25 19 in. Rackmount DVRS operator to ensure FCC/IC Requirements for Radio Frequency Exposure are met. It is the responsibility of the Licensee to ensure that the appropriate separation distances between the antennas and bystanders are established and followed to meet the FCC and IC Maximum Permissible Exposure (MPE) Requirements in any particular temporary fixed location. In situations where a site assessment is not practical, it is recommended that the antennas be located at least 9 feet from bystanders. This should ensure MPE compliance in any Temporary-Fixed application and is likely to be a much greater separation distance than is necessary in most cases. Failure to observe the MPE distance exclusion area around the antenna may expose persons within this area to RF energy above the FCC/IC exposure limits for bystanders (general population).

Vehicular Use

If the 19 in. Rackmount DVRS is set up in a vehicle, Users should refer to the separation distances specified in the manual Product Safety and RF Energy Exposure Booklet for Digital Vehicular Repeater Systems1 to determine the separation distances to be used and the antennas approved for such vehicular use. Failure to observe the MPE distance exclusion area around the antenna may expose persons within this area to RF energy above the FCC/IC exposure limits for bystanders (general population). It is the responsibility of the repeater operator to ensure that MPE limits are observed at all times during transmissions.

Commercial Warranty

• Please reference Futurecom Terms and Conditions of Sale, Section 7 regarding standard warranty.
• Reference manual for basic fixed site installation guidance, and use in a vehicular application.
