  • I am getting an error message saying "Tweaker doesn’t recognize this application software version." The map is damaged.

    Please check which mobile radio (MSU) is interfaced with the DVR, XTL, or APX. The Tweaker software is different for XTL and APX interfaced DVR. For XTL DVR, the latest Tweaker released version is 3.49, and for the APX DVR, the latest released Tweaker software version is 1.14.

  • How do I receive an RMA # in order to return a product for repair?

    Please contact our repair department at 1 (800) 701-9180 ext.1123 , or email us at RMA@futurecom.com.

  • How do I receive pricing on the DVRS, VRX1000 and PDR8000 RF Coverage Solutions Portfolio?

    The DVRS, VRX1000 and PDR8000 are sold exclusively through Motorola Solutions. You may contact your local Motorola account manager or Motorola dealer for pricing.

  • What should be the ‘P25 Preamble Length’ programmed in the DVR/VRX1000 Tweaker?

    This setting must be matched with the APX PSU programming to ensure adequate PSU unmuting The’ Preamble length ‘ setting in the APX  Portable CPS selects the amount of time that determines the minimum number of bit sync preamble packets that are sent at the beginning of all ASTRO transmissions. The amount of time is equal to this Preamble Length setting multiplied by 0.2083 ms.

    The ‘P25 Preamble Length’ setting in Tweaker should match the ‘Preamble Length’ programmed in the ASTRO Conventional system of the APX Portable CPS multiplied by 0.2083 ms.

  • What are the frequency requirements associated with the use of vehicular repeaters?

    To be able to use a full duplex DVRS, you need to obtain at least one pair of frequencies licensed for exclusive DVRS-only use. The same applies to the VRX1000, except it only supports simplex operation (same Tx/Rx frequency). The DVRS/VRX1000 frequencies cannot be the same as those used by the mobile radio, and there are some minimum frequency separation requirements described in the respective DVRS/VRX1000 ordering guides. For more information please refer to the applicable ordering guides in the documentation section of the support page.

  • What mobile radios interface to the DVRS?

    The DVRS can be interfaced with remote mount APX™5500, APX™6500, APX™7500, APX™8500 XTL™2500, and XTL™5000 series mobile radios.

  • What mobile radios interface to the VRX1000?

    The VRX1000 can be interfaced with remote mount APX™2500, APX™4500, APX™5500, APX™6500, APX™7500 and APX™8500 series mobile radios.

  • I see “SYNC ERROR" on the control head.

    Please read the MSU interfaced to the DVR using the Motorola CPS. Export the MSU XML or CSV file from the MSU. Save at a known location on your computer and import it to the DVR / VRX1000 by using the latest applicable Tweaker programming software. Save changes to the DVR / VRX1000 and ensure to reset it.

  • Importing the CSV file of the XTL MSU onto Tweaker gives errors and warnings.

    The problems are normally due to one of the following (CPS changes required only):

    1. If you have hidden fields in the zone channel assignment tables, please use the “unhide all” option to ensure no hidden fields.
    2. If you have aliases enabled (under View, Options tab). Please ensure aliases are disabled (unchecked) and restart your CPS. Ensure the zones are displayed as numbers only (no aliases), and then export a new CSV file. Once your new csv file is exported without hidden fields and aliases, the import into Tweaker should work okay.
  • Is the DVR configured prior to shipping?

    When we ship the DVR from our factory, we program it with a factory default personality and the frequencies specified on the PO. We have no means of knowing what features the end user wants to enable and disable, so most of the programming is to be done in the field by the people familiar with the system and specific customer requirement just like with the Motorola mobile and portable radios.

  • I have an XTL interfaced DVR that was converted to APX DVR, and now I want to convert it back to XTL.

    The APX DVR has to be flashed with the XTL DVR firmware and its EEPROM map has to be downgraded.

    Please call Futurecom support and provide the DVR serial number. Futurecom has to create a rescue file for this serial number, which has to be loaded into the DVR using Tweaker (XTL DVR Tweaker) in order to downgrade the EEPROM.

  • Where can I get the current documentation on DVR, VRX1000 and PDR8000?

    We have most of our current user documentation as well as firmware posted on our website. You can find it in the documents/programming software section on the support page.

  • How many portables and talkgroups can be supported in a P25 system using a DVR?

    The maximum that can be supported is 256.

  • When mobile radios and portable radios are being used with a DVRS solution, do the mobile and portable radios need the 'DVRS Enabled' option for the system to function?

    The MSU 'DVRS' option (GA00631) is absolutely needed in for APX mobile that connects to a DVR.  This allows the DVR to connect with the mobile via the DB25 connector and without it nothing works.  Same with the VRX1000.

    The PSU 'DVRS' option (QA00631) is truly an option.  What it does is bring a number of trunking features to the conventional portable channel.  Things like auto affiliate, trunking tones, network status and P25 OTAR.  If the mobile is on a P25 conventional network then there is no real benefit to this option.  So while the guides may say it is necessary, it really isn’t.

    Things are a bit different with a P25 trunking system.  While the above mentioned features are “nice to have” for many customers, you need to be aware that you lose certain other P25 trunking features without the option. The most important are patch and hot mic.

    P25 is a network type of patch and is more of a merging of talkgroups, forcing subscribers to reaffiliate on a different talkgroup for the duration of the patch.  Any subscriber without the QA00631 option will get disconnected from the network should a patch occur.

    To make matters a bit more confusing, you can order the PSU option on a mobile.  This may initially seem silly, the reason for it is that sometimes fixed DVRS are used as site replacements, covering things like ravines, coves or islands.  In these instances, a mobile may need to communicate with the fixed DVRS and this allows it to have the same “trunking on conventional” features that a portable would have.

  • What are the lengths for the interconnecting (DVR to Mobile Radio) cable for the vehicle mount DVRS?

    The DVR ships with a standard 3 ft. long interconnecting cable, however, at time of order longer cables can be requested  in lengths of 5 ft., 10 ft., 15 ft., 20 ft. and 25 ft.   Spare cables can also be ordered through Motorola Solutions.  The Motorola Solutions order code is DDN9028, please specify the requested cable length at time of order.

  • What is the JF12 number for the DVRS?

    The JF12 number for the DVRS operating between 380-400 MHz is 09176.  The JF12 number for a DVRS operating in VHF is 09176/1.
