Install and User Manual INTRODUCTION The T2000UAV-L is a special version of the T2000 Transponder, designed for operation in unmanned aircraft. This product is not TSO’d due to the OEM nature of the management software. The system consisting of the T2000UAV-L, and the OEM’s management software control should collectively be submitted for compliance to...
The T2000UAV-L requires a standard Gillham code altitude encoder, to supply altitude data over a 10 line parallel interface. The T2000UAV-L features remote switching options, available from the rear DB-25 connector for remote standby and remote ident functions. T2000UAV-L ANTENNA OPTIONS The T2000UAV-L can be supplied with a standard BNC connector located on the rear face of the chassis, adjacent to the DB-25.
Install and User Manual SOFTWARE CONTROL The T2000UAV-L can be controlled by issuing of commands in the form of ASCII characters, sent and received over an RS232 interface. The command set can be used to either poll the transponder of the status of a parameter, or to command a function to a particular setting.
THE UAV COMMAND STRUCTURE The T2000UAV-L is controlled by a series of simple commands. The T2000UAV-L can be commanded to set a code, and to operate in a particular mode. Once the code is set, and the operating mode decided, the T2000UAV-L will operate until another command is received.

The ident function is performed at the request of ATC to “squawk ident”. To initiate the ident function the “i” parameter is set to s. The T2000UAV-L will switch to ident mode, which will add an additional data bit to the outgoing replies.
The equivalent function for the T2000UAV-L is the “r” command which activates the reply annunciator. When activated (r=y), the T2000UAV-L will send a single * character, if there was a reply made in the preceding 3.6 seconds. When not activated (r=n), no character is sent.
Although it is unlikely that the encoder source in a UAV installation will require switched power from the T2000UAV-L, it is recommended that the ground be wired with the data lines in all cases. This will ensure correct signal operation of the Gillham code.
7.0 COAXIAL CABLE The T2000UAV-L 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.
CABLING Microair recommends that wiring for all of the T2000UAV-L’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.
There is no software OFF command. When power is removed from the T2000UAV-L, it will not respond to any software command. When the T2000UAV-L is turned on, it is always in standby mode. The mode A code will default to the last mode A code used.
