POWER ON/OFF
The T2000UAV-L has no ON/OFF control function. The unit is on from the moment power is applied to the
unit. 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.
IMPORTANT NOTE
Always bring the T2000UAV-L to standby before turning off the power. If
the transponder is powered off while it is in the process of transmitting,
damage may occur to the internal power supply and/or the transmitter.
Damage of this type is not covered by the warranty.
No mode C code will be outputted until the T2000UAV-L is supplied with altitude data (either serial or
Gillham) which can be encoded by the transponder.
8.3
SUPPRESSION IN / OUT
The suppression IN line is wired to other avionics such as DME, to “suppress” the transponder’s transmissions,
at times critical to the other equipment’s operation.
The suppression OUT line does the reverse of the IN line. It is wired to other avionic equipment to allow the
T2000UAV-L to “suppress” their transmissions at times critical to the T2000UAV-L’s operation.
Seek the advice of a qualified Avionics Technician before attempting to wire out these functions. If certified
equipment is modified to operate in conjunction with the T2000UAV-L installation, then the installation of that
equipment must be re-inspected and re-approved before operation.
8.4
EXTERNAL STANDBY
The external standby can be wired to a remote switch. When the line is taken to ground the T2000UAV-L will
return to standby mode, and stay there regardless of the value for “s” parameter. The “s” parameter cannot be
queried while the external standby line is grounded.
Once the external standby line has been “released” from ground, the T2000UAV-L will revert to the last “s”
parameter setting.
