TMAA11-06 Extended Single Head Upgrade Kit
Installation Instructions
Introduction
The TMAA11-06 upgrade kit can be used when extended distances are required between a
TM8250, TM8255 or TM9155 radio body and graphical-display control head. This enables the
control head to be installed away from the radio body in difficult or isolated locations, up to a
maximum 1km. The upgrade 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 the control head.
The upgrade kit provides the following items:
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)).
Refer to the radio installation guide for further information such as mounting the radio body
using the U-bracket, installing the antenna, and radio body power connections.
