6. Installation Setup and Test
There are no configuration items on the TN72. This section describes the
correct configuration for a connected Trig TT21 or TT22 transponder and
assumes that the transponder is using software version 2.12 or later. The
process for configuring the TT31 transponder is similar. Earlier transponder
software versions can use the TN72 as an uncertified NMEA position source,
but may not recognise the later settings described here.
6.1 Configuration Items
6.1.1 GPS Input
The TN72 outputs NMEA encoded position and velocity data as well as
additional integrity information used for TSO-C199 compliance. The
transponder can therefore be configured to operate using the TN72 as an
uncertified NMEA position source, as a TSO-C199 TABS position source, or
in certain circumstances as a FAR 91.227 compatible position source. Select
one of the following:
NMEA 0183 Transponder sends ADS-B data, SIL set to zero.
C199 TABS Transponder sends ADS-B data in accordance
with TSO C199; SIL = 1, SDA = 1.
Trig TN72 SIL 3 Transponder sends ADS-B data in accordance
with FAR 91.227; SIL = 3, SDA = 2.
6.1.2 GPS/TIS Line Speed
The TN72 runs at 9600 bps.
Note: The TIS output and GPS input speeds are not separately
controlled on the TT21/TT22. Not all combinations of GPS input and
TIS output will work if the TIS device operates on a fixed speed other
than 9600 bps.
