The MPT1327 Option Board (Part 2)



The MPT1327 Option Board is configured by means of the MPT OB CPS and (host radio) MOTOTRBO CPS. In order to operate, the radio needs to be provisioned with 16 analogue channels; in the first zone with Option Board ticked. The frequencies are irrelevant as this will be controlled by the Option Board. This is described in some detail in this presentation.

  1. Dear Wayne,
    we already have a trunk system MPT1327 with five channels and analoge handheld radios GP680Ex,
    now we are planning to upgrade to digital handheld radios with MPT1327 option board, the problem that there are some points like behind buildings, behind a small hills that has a very weak receive signal, is the digital radios has a high receive sensitivity level than analogue? other thing, can i extend the coverage to cover all weak points by using like broadband booster or anything else?
    Thanks in advance.

    1. You may find that the MOTOTRBO radios perform better in digital mode but in analogue mode there will be no difference.
      It may be possible to extend the coverage by means of a Passive Repeater or similar but there are many factors which you need to consider and which I cannot go into without in-depth knowledge of your system. It would be best if you make contact with a Motorola Engineer who can advise you: click on Links>>>Where to get support.

  3. what about the site survey program! Is it possible to use it with mototrbo hand-held ATEX including MPT1327 option board to get RSSI of my analogue trunk system?

    1. I assume you are referring to the MOTOTRBO Site Survey tool? This tool only works in digital mode so will be of no use to you at present.
      It is possible however to manually plot coverage using the RSSI readout and a GPS then recording this information on a map. The RSSI can be viewed on a display model by pressing 120#.

  4. Thank you very much for your great information, and Merry Christmas for you and your family,
    I have some queries out of this topic about telemetry feature, i tried to connect many types of relay including solid state (3-30 volt) with our mobile DM3601 PIN OUT but the (5V) telemetry out unable to run my 5 volt relay, maybe because the current is very low (1 mA),
    I hope if you could advise me if there is any way to run my relay and thus run my circuit.
    thanks a lot,
