T200
TRANSCEIVER
OPERATING INSTRUCTIONS
These operating instructions are intended to provide the user with sufficient information to install
and operate the unit correctly.
The Tactical Electronics model T200 is a single channel synthesized transceiver which operates in the
216 to 219MHz frequency band. The unit is intended to fulfil the numerous OEM applications by
virtue of its highly reliable design, miniature size and quality manufacture.
INSTALLATION
The T200 is intended to fit easily and with minimum space requirements into the user's own
equipment housing. The complete module is housed within a tin-plated enclosure and is secured
by means of four 10mm metal screws which locate in the four corners through the lower
screening cover. DO NOT overtighten these screws during assembly.
CONNECTION
The radio antenna connects by means of a BNC miniature coaxial connector. All other
connections to the T200 transceiver are made using a standard 9-way D type connector as
detailed in the table below.

PROGRAMMING
The software supplied with the T200 transmitter is the single channel TPRG.exe program. The
software can be run on a PC with the serial port connected to pin 7 of the transmitter via a
suitable adaptor as shown in Figure 1. The unit may be programmed in-situ provided that pin 7
is available. There is no feed-back facility with this circuit, and for this reason, the TPRG software
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 possibility of
spurious programming.
RUNNING THE SOFTWARE
Please note that mouse operation is not supported with this program
Figure 1 Programming adaptor
1. Connect TX00 to a suitable supply and to the PC using the programming adaptor.
2. Insert the TPRG disk into drive A and type:
A:TPRG 
3. The user is then prompted to enter the serial port number of his PC which is used to
communicate with the TX00 transmitter. Enter 1 or 2.
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 INFORMATION
The following table gives an indication of the typical ranges to be expected between a transmitter
and receiver that have simple end-fed dipole antennas.
The following assumptions have been made in the calculations:
line-of-sight between antennas
0dB gain for the transmitter and receiver antennas
0dB loss for connectors and cables between the antenna and the radio connector
20dB fade and environmental margin
-100dBm received signal strength, allowing for digital and analog signals
