3.2 Installing the Antenna
This section provides information on installing an external antenna within
the RF exposure limits.
Install the external antenna (not supplied) according to the antenna
manufacturer’s instructions. Good quality 50 Ωcoaxial cable must be used,
such as RG58 or UR76.
Notice Route the cable in a manner that minimizes:
■coupling into the electronic control systems of the vehicle
■coupling of electric vehicle systems, such as alternators, into the
radio.
Avoid sharp bends in the cable. These distort the cable and alter its
electrical characteristics.
Warning RF exposure hazard. To comply with FCC RF
exposure limits, mount the antenna at a location such that no
person or persons can come closer than 44 inches (1.1m) to the
antenna. For VHF radios, mount the antenna centrally on the
vehicle roof, with a gain of 2.15dBi or 5.15dBi.
Terminating the
Antenna Cable 1. Run the antenna cable (not supplied) from the antenna to the radio
mounting location and cut it to length, allowing approximately eight
inches (20 cm) excess at the radio end.

14 Installing the Radio TM9100 110W Mobile Radio Installation Guide
© Tait Limited October 2012
3.3 Connecting the Power Cable to the Power Source
Power is supplied to the 110W mobile via a cable with a DB15 connector
(provided). This plugs into the external RF amplifier, which provides power
to the back of the radio body via an internal loom.
Notice This radio is designed to operate from a nominal 12V negative
ground supply and may draw up to 30A of current. The radio will tol-
erate a supply voltage range of 10.8V to 16.6V at the radio.
Selecting the Power
Source In passenger vehicles, the radio is always connected directly to the battery.
In trucks, where direct connection to the battery is often not possible, the
radio can be connected to a suitable terminal inside the fuse box that is
connected directly to the battery.
24V-to-12V
Converter In vehicles with a supply voltage larger than 16.0V, such as many trucks, it
is essential to provide a suitably rated 24V-to-12V converter. This will
isolate the radio from excessive battery voltage and provide the correct DC
operating conditions. Note that most 24V-to-12V converters already fitted
are not rated sufficiently.
Standby Current When using the ignition signal to turn off the radio, the standby current is
reduced to <3mA. Otherwise, the standby current is 50mA.
Connecting the
Power Cable Notice Although it is possible to connect the radio in line with the
vehicle ignition, this is not recommended, as it may draw too much cur-
rent and damage the vehicle wiring and steering column or ignition
switch. This may also cause the supply voltage of the radio to drop below
the specified level.
Notice Disconnecting the vehicle’s battery may cause problems with
some electronic equipment, such as vehicle alarms, engine management
systems, and in-car entertainment systems. Check that the vehicle owner
has the necessary information to make all electronic equipment function
correctly after battery reconnection.
Notice If the battery is not disconnected, exercise extreme caution
during the installation and install the fuses only when the installation is
ready to be checked. For more information, refer to “Checking the
Installation” on page 22.
1. Disconnect the vehicle’s battery unless specifically prohibited from
doing so by the customer, vehicle manufacturer, agent, or supplier.
Notice Route the cable in a manner that minimizes coupling of elec-
tric vehicle systems such as alternators into the radio.
Notice Protect the power cable from engine heat, sharp edges and
from being pinched or crushed.

TM9100 110W Mobile Radio Installation Guide Installing the Radio 15

2. Run the supplied power cable (or one with a higher current rating)
between the radio’s mounting position and the vehicle battery (12V)
and cut it to length, allowing approximately 8 inches (20 cm) excess
at the radio end.
3. Cut the negative (black) and the positive (red) wires where the in-line
fuse holders will be placed (as close to the power source as possible).
Notice Do not install the fuses until the installation is ready to be
checked. For more information, refer to “Checking the Installation” on
page 22.
4. Insert each end of the negative wire into each of the fuse
crimp-terminals and crimp them to force the metal contacts onto
the wires.
5. Push the two crimp-terminals into the clear plastic fuse cover. Close
the cover while the next steps are completed.
6. Repeat steps 4 and 5 for the positive wire.
7. Connect the negative wire to the battery ground terminal.
8. Connect the positive wire to the battery positive terminal.
Notice Do not install the fuses until the installation is ready to be
checked. For more information, refer to “Checking the Installation” on
page 22.
3.4 Installing the Remote Control Head
1. Choose a suitable location for the control head.
2. Mount the control head according to the instructions supplied (IPN
402-00020-xx). Make sure that you follow the warnings and cautions
in these instructions.
The remote control head back (TMAA03-03) has already been fitted to
the control head and the dual RJ-45 torso interface (TMAC34-1T) has
already been fitted to the radio body.)

provided. The microphone must be within reach of the user but in such a
position that the PTT (press-to-talk) key cannot be inadvertently activated
or jammed.
Warning Safe microphone mounting. Mount the micro-
phone where it will not interfere with:
■the deployment of passenger airbags
■the vehicle operator controls
■the vehicle operator’s view.
Notice Only install the microphone clip provided. If a non-standard
microphone clip is used, the correct operation of the microphone hook-
switch cannot be guaranteed.

3.6 Connecting to the Ignition Signal
Ignition sense allows the radio to be turned on and off with the ignition key
of the vehicle. The TM9100 110W mobile radio is already fitted with an
ignition sense kit, however it must be programmed for ignition sense
operation.
If ignition sense operation is desired:
1. Make sure that the AUX GP13 line has been programmed for igni-
tion sense.
2. Run the yellow wire from the back of the mobile body (underneath
the 110W RF Amplifier) to a 12V signal controlled by the ignition
key.
3. Secure the cable with cable ties using the small holes in the side of the
chassis.
The logic thresholds for AUX GPI3 are based on 3V3 levels. However,
AUX GPI3 can be connected directly to a +13.8V ignition signal.

3.7 Connecting a Remote Speaker
If a high-power remote speaker is required, Tait recommends using the
TMAA10-03 high-power remote speaker for 25W radios. Installation
instructions (IPN 402-00010-xx) are provided with the speaker.
If a different speaker is used, it can be connected to the flying-lead connector
already installed in the power connector (b), or connected using the two
spare receptacles that are provided with the installation kit (c).
1. Run the speaker cable to the radio, then (underneath the RF ampli-
fier) alongside the ignition sense cable to the back of the radio body.
2. Secure the speaker cable with cable ties using the small holes in the
side of the chassis (see Figure 3.3 on page 17), as was done for the
ignition sense cable.
3. Connect the remote speaker connector to the flying lead connector
(shown in Figure 3.4 option b).
If connecting the speaker directly to the power connector
(Figure 3.4 option c), connect the speaker to pins 2 (SPK–) and
3 (SPK+) of the radio body’s power connector (see Table 3.1).

3.8 Connecting to an Emergency Switch and/or
External Alert Devices
The auxiliary connector can be used to connect external devices and signals
that are typically connected to a radio. These devices and signals include:
■an emergency switch to power up the radio (if required) and then enter
emergency mode
■external alert devices
■other external devices or signals.
Table 3.2 gives an overview of the connector pins and their possible uses.
Emergency Switch The radio allows for connection of an emergency switch to any input line
to enter the emergency mode. If the switch is connected to the AUX GPI2
input line, the radio can also use ‘emergency power sense’ to power up the
radio to enter the emergency mode.
The selected input line must be programmed to ‘Enter Emergency
Mode’ and active to ‘Low’. To use ‘emergency power sense’, hardware
link LK3 must be fitted (factory default), and AUX GPI2 must be used.
For more information, refer to the service manual and the online help of
the programming application.
Connect a normally open switch between the pin of the input line
(pin 5 for AUX GPI2) and pin 15 (AGND) of the
auxiliary connector.

External Alert
Device The radio allows for output to external alert devices using the digital GPIO
lines of the auxiliary connector and the internal options connector.
AUX GPIO4 can be fitted with a power MOSFET (Q707) to directly
connect external alert devices (e.g. flashing light, buzzer, horn relay) to the
radio. Also, resistor R768 must be removed.
Notice While the MOSFET is rated at 12A (with heat sink), the max-
imum allowable current of the connector and radio’s earthing system is
2A. Therefore, a horn must not be connected directly to the radio.
A horn relay must be used.
The selected output line must be programmed to ‘External Alert 1 or 2’,
active to ‘Low’, and signal state to ‘Momentary’.
Connect the external alert device to the pin of the output line (pin 10
for AUX GPIO4) and pin 8 (+13V8 SW) of the auxiliary connector
(or a different positive battery connection).
This means that the negative side of the alert device must be con-
nected to AUX GPIO4 and the positive side to pin 8 (+13V8 SW).
The external alert device must be capable of accepting a voltage of
between 10V and 18V.
Other External
Devices or Signals If you want to connect any other Tait equipment, follow the instructions
supplied with the device.
Check Table 3.2 to make sure that the auxiliary connector pins needed
are not already used by the 110W RF amplifier.
For third party external devices, consult Tait Support or the 3DK Hardware
Developer’s Kit Application Manual for detailed information about the pins
and their signals.
If the signal is available and appropriate, disconnect the loom between the
RF amplifier and the radio body. Open up the auxiliary connector (DB15)
and wire in the desired signal.
