Installation Manual About This Document This manual describes the various installation configurations available for the Microair T2000SFL Transponder, including connection to a separate altitude encoder. Microair reserve the right to amend this manual as required, reflecting any enhancements or upgrades to the T2000 Transponder series.
It would be a really good idea if you read through this section of the manual BEFORE you start installing your Microair T2000SFL Transponder. If it is too late, and you are reading this message after the fact, perhaps the information that follows can help you sort things out.
MICROAIR T2000 SFL PANEL INSTALLATION The T2000SFL weights only 600g (1 lbs). The four M4 x 12mm machine screws are sufficient to support the transponder. No rear support is required unless the panel structure itself is too weak to support the load.
T2000SFL, and is equal to the aircraft supply voltage. This power is switched when the T2000SFL is turned on. If the encoder is to be powered separately, it is recommended that the ground wire is run to the T2000SFL, to ensure correct switching of the data lines.
To avoid possible interference the antenna must be mounted a minimum of 0.3m (12 inches) away from the T2000SFL. The transponder antenna outputs high level of RF energy, and should be located at least 1m (3ft) away from vulnerable part of the human body, or be separated by a metal panel.
5.0 COAXIAL CABLE The T2000SFL allows for 1.5dB cable loss from the unit to the antenna. The installer should consider carefully what type of coaxial cable is to be used, so that this loss limit is not exceeded. The cable should be terminated with silver plated BNC connectors where possible.
D series plug if it not secured. Where possible, wiring is to be run separately to the coaxial cable. Microair recommends that wiring for all of the T2000SFL’s functions and connections be run at the time of installation, even though they may not be required at this stage. Adding additional wiring to the loom at a later stage may be very difficult.
Installation Manual 6.2 Audio Beep The T2000SFL beep function when set to ON, will emit a beep tone on this line. Audio beep should be taken to the Auxiliary input of the aircraft’s radio or Audio Panel. When connecting the beep function to the Microair M760 transceiver, simply join the beep line directly to any headphone line (orange wire in factory supplied harness).
For this reason Microair strongly recommends that all transponder installations be calibrated at the time of installation, and at periods of not greater than two years thereafter. T2000SFL Installation Manual 01R7-1 Page 11 of 23...
