OVERVIEW
Thank you for purchasing a MINDA Intelligent Transmitter, which uses a low-power
microprocessor for ‘house-keeping’ and offers the following programmable options:
• A Unit Identity Code (TX ID number 1,2,3,or 4) which will allow a single receiver to identify up to
four different transmitters.
• A very secure Family Identity Code, enabling secure use of multiple groups of transmitters and
receivers together in the same location - without receiving alarms in ALL receivers.
• Full compatibility with other MINDA equipment
• Alarm signal repeat at programmable intervals
• Automatic transmission of Confidence signals is possible
• Transmitter ‘Low Battery’ alert sent to receiver
• Very low power consumption
Keep this instruction manual in a safe place - it contains important information and helpful tips
which will assist you to obtain the best possible performance from your new MINDA system.
OPERATING FREQUENCY
All MINDA systems for use in the United States operate on a frequency of 418MHz in the UHF
band. The operating radio frequency cannot be changed to suit a specific customer’s needs.
BATTERY INSTALLATION
The MINDA TX-600 belt transmitter requires a custom built internal 12 volt lithium battery. These
batteries will last a very long time. When a replacement becomes necessary, please contact
Tactical Technologies Inc. for pricing and delivery.
To install a new battery into the TX-600 belt transmitter, unzip the zipper found on the underside
of the belt. The battery fits snugly inside the belt, and is secured by friction. The old battery can
be removed by carefully pulling the battery out from the belt, and disconnecting the two-pin
molex-type connector found on the leads coming from the battery. Insert the new battery by
working it into the belt, taking care to ensure that it is orientated in the small manner as the
original battery. The tow pin molex-type connector should be joined with the mating connector
found inside the belt. Take care to mate the connectors according to the keyed tongue.
OPERATION
The TX-600 will only communicate with an appropriate MINDA receiver, such as the RX-400
pocket receiver, or the RX-500 portable/mobile/tabletop receiver.
The TX-600 is operational immediately upon inserting the battery.
The unit is equipped with an On/Off switch that is found inside the zipped compartment on the
underside of the belt. To turn the TX-600 ON, slide the switch with your finger to the ON position.
To turn the TX-600 off, slide the switch to the OFF position.
The TX-600 has two push-button transmit switches. One button is located at the center of each
of the two round 'silver' decorator stud found on the 'tounge' side of the belt. The buckle side of
the belt has two similar studs, but these DO NOT contain switches.
When the belt is being worn, the button closest to the FRONT of the body (or closest to the END
of the tongue of the belt) sends a RED ALARM to a MINDA receiver. The button closest to the
REAR of the body (or farthest away from the end of the toungue of the belt) sends a GREEN
alarm to a MINDA receiver. Press and hold either button for at least 1 second to transmit your
alarm.
The TX-600 may be programmed to automatically transmit a GREEN or RED 'confidence alarm'.
This signal may be programmed to transmit every few seconds or every few minutes. The timing
of this transmission begins upon sliding the On/Off switch to the ON position. See the section on
CONFIDENCE MODE for more details.
WHAT IS ACTUALLY TRANSMITTED
Whenever a ‘MINDA’ transmitter operates, the actual digital data message transmitted contains
all of the following pieces of information, repeated a number of times:
< I am a ‘MINDA’ transmitter >
and < My Family Identity is ‘xxx’ >
and < I am Unit I.D. ‘y’>
and < My alarm status is ‘red/green’ >
and < My battery status is ‘OK/low’ >
If the first two pieces of data in the above message exactly match the information programmed
into the ‘MINDA’ receiver, then the rest of the information will be decoded and displayed on the
LEDs. If they do not match, the entire message is ignored.
UNIT IDENTITIES
A MINDA TX-600 Intelligent Transmitter can have each of its four possible Unit Identities (1, 2, 3
or 4) configured to signal in different ways and with different timings to suit particular operational
needs.
The user can easily alter the pre-programmed Unit Identity Code (shown on the label on the
inside of the belt) whenever required.
CHANGING THE UNIT IDENTITY
A permanently change of the Unit Identity of a MINDA TX-600 transmitter must be performed at
the factory.
The Unit Identity of the TX-500 transmitter can be temporarily changed by simultaneously holding
down both push buttons for about 2 seconds. Each time the two buttons are pressed together
the sequence will cycle through all four possible identities (ie. 1,2,3,4,1,2,3...) but note that if the
power supply is interrupted by switching off or changing the battery the transmitter will revert to its
start-up Unit I.D. once power is re-applied.
Please note:
This user option can, if required, be modified in format or completely inhibited by suitably reprogramming the unit.
Note: Check that you know the Unit Identity (1,2,3,or 4) of the transmitter that you intend to use
by sending a test signal to a ‘MINDA’ receiver and noting which of its LEDs illuminates. If
necessary, change the Unit Identity to the one you require.
ANTENNA
The transmitter's antenna is an internal small black wire. Never attempt to shorten, fold up or
modify the transmitter antenna since such action will seriously degrade the range of the MINDA
system.
FAMILY IDENTITY CODE
Each MINDA system, when supplied to a customer, will have already been programmed at time
of manufacture with a common default ‘Family Identity Code’ (hexadecimal 94) enabling it to be
used with any other of the standard MINDA products. The Family Identity Code for a particular
family of MINDA units can easily be re-programmed by returning all of the equipment to Tactical
Technologies Inc. or, if a MINDA computer interface package has been purchased, by the user.
For a MINDA system to operate with, and recognize up to four independent transmitters, the
Family Identity Code of the receiver and transmitter(s) all have to match AND each of the
transmitters must have a different Unit Identity (1,2,3 or 4).
A microprocessor controlled MINDA receiver will only respond to signals from those transmitters
sending the same Family Identity Code that it has been pre-programmed to accept. This
capability minimizes the risk of interference between similar systems that happen to be operating
within radio range of one another. It is absolutely vital therefore, to ensure that all transmitter
and receiver units that have to operate together are programmed with the same Family Identity
Code. Signals received from any ‘alien’ transmitter operating within range will not be decoded
and, instead, treated by the receiver as radio interference on the channel.
LOW BATTERY WARNING
When the battery voltage of MINDA TX-600 transmitter drops to a level where battery
replacement is desirable, each subsequent transmission made will be ‘tagged’ to indicate this fact
to the receiving end. When a MINDA receiver recognizes a ‘tagged’ signal from a MINDA
transmitter, the LED indicator appropriate to that transmitter’s Unit Identity will start to ‘blink out’
briefly about once per second.
BATTERY LIFE
The MINDA TX-600 transmitter consumes about 400 times more power when actually
transmitting compared to that required when it is dormant. If the unit is programmed to send
frequent confidence transmissions, or is used manually a great deal, the battery drain will be
significantly increased. The following table shows the typical life that can be expected of a
transmitter in relation to the time interval between automatic transmissions made.

The above times have been calculated on the assumption that the MINDA TX-600 transmitter is
programmed to send the default (normal duration) automatic confidence signal and that it has
been fitted with a new battery and switched on to run continuously. Switching the unit on and off
frequently and manually sending a number of alarm signals longer than 1 second in length both
consume additional power from the battery and will reduce its life below the estimated figures
shown above.
CONFIDENCE SIGNALLING
A MINDA TX-600 intelligent transmitter can be programmed so that for any or all of the four
identities it can assume a GREEN or RED transmission as an “I’m here and OK” signal.
In order for confidence to be transmitted, the transmitter must be in the MODE of the
programmed signal.
The transmitter defaults to GREEN mode upon reset, or when it is turned on.
If Confidence mode is programmed for GREEN MODE Transmitter 'starts up' in GREEN MODE, therefore confidence is automatically enabled upon start
up.
Confidence signal will be transmitted at each interval.
If a RED alarm is pressed manually - confidence mode is temporarily disabled.
To re-start confidence mode, press GREEN alarm manually.
If Confidence mode is programmed for RED MODE Transmitter 'starts up' in GREEN MODE, therefore confidence sequence must be STARTED by
manually activating a RED alarm.
Confidence signal will then be transmitted at each interval.
If a GREEN alarm is pressed manually - confidence mode is temporarily disabled.
To re-start confidence mode, press RED alarm manually.
...Here's an idea...
If a MINDA receiver has been programmed (1) to remain silent whenever a valid ‘green’
transmission is received, and (2) to signal an alarm if nothing is heard from one or more of its
associated transmitters within a pre-designated period of time, then the following scenario
becomes possible:
When an initial ‘green’ transmission is received from any of its associated transmitters the
receiver will remain silent and one of four pre-programmed internal time-clocks within it will start
counting. Each subsequent ‘green’ transmission from that same transmitter unit will again be
received silently and reset the time-clock to zero. If, however, the pre-set time period elapses
before another ‘green’ signal has been received then the appropriate LED on the receiver will
begin to flash and a ‘Lost Signal’ audible alarm will be signaled. Until the person using the
receiver pushes the ‘RESET’ button to clear the audible and visual alarms, a warning alert tone
will continue to be emitted at the pre-programmed interval(s).
If a different transmitter unit (but of the same family) is then received, another time-clock
commences operation independently in the same way as described above. If a valid ‘red’ alarm
signal is received from any of its associated transmitters the receiver will, of course, generate all
of the normal audible and switching alarms.
In a situation where a receiver and an intelligent MINDA TX-600 transmitter are being used to
protect a person close-by but out of sight, the regular confidence transmission will keep the
receiver silenced all the while it is present. If the transmitter moves out of radio range, its battery
fails, or it is otherwise disabled the receiver will emit an alarm signal as soon as the confidence
signal has been missing for the pre-programmed period of time. This enables, for example, a VIP
to be protected at night by a bodyguard in an adjoining room, or a person going into a potentially
hazardous situation to be supported by a back-up team in a vehicle close-by. The intelligent
MINDA transmitter will send the confidence signals entirely automatically without disturbing the
user unless he or she wishes to send a ‘red’ alarm signal in the usual way.
TROUBLESHOOTING GUIDE
If signals from a TX-600 transmitter are not being received by a MINDA receiver the following
tests should be undertaken:
1.) Check that the transmitter is not out of receiver range by temporarily reducing the distance
between the units to 10 yards or less. Begin to increase the distance again until signals
transmitted are not received reliably. This will give a good indication of the likely maximum
working range that can be achieved in the particular location used for these tests.
2.) If the units still fail to communicate, check that the MINDA receiver is operating correctly by
pressing and releasing its RESET button and confirming that the eight LEDs briefly illuminate. If
this does not happen, replace the battery in the receiver with a new one and try again.
3.) Confirm that interference or another signal is not jamming the receiver. If necessary, move the
receiving location away from the source of the interference.
4.) Check that other transmitters (in the same family) are being received OK.
5.) Return the faulty transmitter for check-out and/or repair.
MAINTENANCE
The MINDA transmitters require minimal maintenance. Problems with the internal electronics are
unlikely unless the unit has been subjected to some physical damage. The most likely sources of
difficulty will be associated with the transmitter battery or its contacts, the mechanical switches, or
the antenna. These items should be inspected regularly and corrective action taken, where found
to be necessary.
