MINDA PERSONAL PROTECTION SYSTEM TX-600 INTELLIGENT BELT TRANSMITTER Operating Instruction Rev 1.1 June 2000 Tactical Technologies Inc. 1701 Second Ave Folsom, PA 19033 610-522-0106 www.tacticaltechnologies.com 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 helpf ul 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 t he 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 re- programming 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 w hich 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’ (…

IP9TX600 TX-600 CIRCUIT DESCRIPTION This intelligent belt transmitter is comprised of a small PCB with a PIC 16C84-04P micro-processor with its associated components, a 5 volt regulator, and various other discrete components. A Radiometrix TX2 418 MHz saw oscillated transmitter module and two activation switches are connected to the PCB. A 9- volt flat battery system is fitted into clips attached to the PCB to provide power. A MINDA 'family code' is pre-programmed into the eeprom of the PIC micro-processor along with other user-selectable operating parameters by connecting a lead from an IBM compatible Personal Computer to the 8-way socket on the PCB. The unit's ID (1,2,3,or 4) is set up on the PC Board via solder pads. Pressing one of the two buttons on the belt activates the transmitter. The PIC microprocessor causes battery power to be applied to the Radiometrix TX2 module. At this time, serially encoded data (including the status of the battery, and w hich button was pressed) to the modulation-input line of the TX module. There are numerous programmable options available to the end user. These are fully described in the operator's manual.
