TMAA11-07/TMAA11-08
Extended Dual Head Upgrade Kits
Installation Instructions
Introduction
The TMAA11-07 or TMAA11-08 upgrade kit can be used to convert a TM8250 or TM8255
mobile radio (single radio body and graphical-display control head) to a dual-head radio
system. In a dual-head radio system, elements of the user interface (such as display content,
internal speaker audio, and LEDs) are duplicated on both control heads. This enables
multiple users to share the same radio.
In addition, the upgrade kit allows one or both control heads to be installed away from the
radio body in difficult or isolated locations, up to a maximum 1km. The kit includes a
transmit/receive pair of extender boxes to provide the necessary processing and protection
of signals over longer distances, and a control-head interface box to locally re-power one
or both control heads.
The upgrade kits provide the following items:
extender box (x2)
Not Illustrated: cable grommets (x4), and extender/interface box washers and screws
In addition to the items in this kit, you also require two matching lengths of crossover
network cable up to 1km each. The cable may be a combination of structured cabling, patch
cables and adaptors. The crossover configuration must be a two-pair crossover, wired 1-3,
2-6, 3-1, 4-4, 5-5, 6-2, 7-7, 8-8 (as per TIA/EIA T568A and T568B).
If using off-the-shelf crossover cables or adapters, be aware that some are four-pair cross-
over and are therefore unsuitable. If using existing building network wiring, ensure there
is no other hardware in the circuit such as routers or switches.
You also need suitable equipment to connect the control-head interface box to a power
supply (such as a power cable assembly (IPN: 219-02883-00), or a power adaptor rated to
provide 10.8–16V DC at > 2A (IPN: 009-0001x-00, where x is 4 to 7 depending on
region)).
