T100 TRANSCEIVEROPERATING INSTRUCTIONS1892 115896.00(3.8") 3.40 (0.134")diameter in4 placesFIXING CENTRES FOR ENCLOSURE(PLAN VIEW)Dimensions in mm (inches)D TYPERF CONNECTORThese operating instructions are intended to provide the user with sufficient information toinstall and operate the unit correctly. The Tactical Electronics T100 transceiver  is intended to fulfil the numerous OEM applicationsby virtue of its highly reliable design , miniature size, and quality manufacture.MOUNTING DETAILSThe T100 is intended to fit easily and with minimum space requirements into the user's ownequipment housing. The complete module is housed within a tin-plated enclosure and issecured by means of four 10mm self-tapping sheet metal screws which locate in the four cornersthrough the lower screening cover.  DO NOT overtighten these screws during assembly.Tactical Electronics Corporation
CONNECTIONThe radio antenna connects by means of a BNC coaxial connector.  All otherconnections to the T100 transceiver are made using a standard 9-way D type connector asdetailed in the table below.

Figure 1   Programming adaptorOPTIONSFrequency and Channel spacingThe T100 is available in both 12.5 and 25kHz channel spacing variants within the followingfrequency bands:135 - 140 MHz150 - 180 MHz180 - 210 MHzRF connectionAs well as the standard BNC coaxial connector, the T100 is also available with a SMB orflying lead RF connection. Contact Tactical Electronics Corporation for details.Transmit PowerThe maximum transmit power of the unit is 2W.  This can be adjusted down to 100mW ifnecessary for differing approved bands of operation.CHANNEL SELECTION & PROGRAMMINGThe software supplied with the T100 transmitter is the TLSPRG.exe program.  The softwarecan be run on a PC with the serial port connected to pin 7 of the transmitter via a suitableadaptor as shown in Figure 1. The unit may be programmed in-situ provided that pin 7 isavailable. There is no feed-back facility with this circuit, and for this reason, the TLSPRGsoftware repeats the programming three times to eliminate error.  This version of software is programmed by a series of 8 byte data packets at 1200 baud.Each packet includes a 16 bit sync code and an 11 bit checksum to eliminate the possibilityof spurious programming.
RUNNING THE SOFTWAREPlease note that mouse operation is not supported with this program1. Connect the T100 transceiver to a suitable supply and to the PC using theprogramming adaptor.2. Insert the TLSPRG disk into drive A and type:A:TLSPRG <return>3. The user is then prompted to enter the serial port number of his PC which is used tocommunicate with the TX00 transmitter.  Enter 1 or 2.4. Note: Do not select the port with the mouse connected as this will cause theprogram to run incorrectly.After the software has successfully loaded the screen displays the following prompts:Enter frequency in MHz?The user can then enter the required operating frequency and then ‘0' to quit.RANGE INFORMATIONThe following table gives an indication of the typical ranges to be expected between atransmitter and receiver that have simple end-fed dipole antennas.The following assumptions have been made in the calculations:line-of-sight between antennas0dB gain for the transmitter and receiver antennas0dB loss for connectors and cables between the antenna and the radio connector20dB fade and environmental margin-100dBm received signal strength, allowing for digital and analog signalsRange versus TX powerFrequency (MHz) Power (mW) Power (dBm) Range (km) Range (miles)173 100mW 20 13.8 8.5173 500mW 27 30.9 19.1173 1W 30 43.5 27.0173 2W 33 61.5 38.2
