Technical Support / TQ Avionics (formerly Dittel) KTX2 Mode S Transponder
« on: January 08, 2020, 10:52:52 pm »
Can anyone tell me if you can connect up a TQ Avionics (formerly Dittel) KTX2 Mode S Transponder to a pilot aware I have received the following information from the makers teschnical department but I am not confidant to committing to buy the unit only to find its a dead duck.
the latest version of software and the manual offers the following:
The only information I found was this:
A GPS source can be connected to the serial interface (RS232) providing GPS position data (Extended Squitter).
Requirements:
- Software Revision 0101 and higher
- Required data format of the GPS hardware: Standard NMEA0183 RMC data stream including the RMC-sub-format (4800/9600/38400 Baud).
- GPS hardware needs to be connected to pins 2 and 13. Power supply needs to be provided separately considering the required operating voltage for the GPS hardware.
ADS-B Out. Connecting to a Mode S transponder.
On contacting the makers I received the following information:
I did not find all information I need.
Our Transponder needs 4800 or 9600 baud NMEA Signal in RS-232 level but only the RMC signal of the NMEA signal. If your Pilot Aware Unit provides more information the KTX2 doesn´t work correctly.
One of the useful features of PilotAware is the ability to share its GPS information with third-party
equipment. This is particularly useful when you want to use the GPS in PilotAware as the uncertified
GPS source to convert your Mode-S transponder with extended squitter (ES) to transmit ADS-B-Out.
To do this you need to obtain a USB-RS232 converter in order to connect to your transponder, each
model/type will be different.
Once connected to PilotAware you will need to manually configure the USB port for Baud Rate and
Transponder type, each type requires differing NMEA messages and rates. For example, to connect
PilotAware to your Funke transponder to give ADS-B Out. You will need to use a USB -RS232
converter cable. This must be "true" RS232, +/- 12V, and NOT the "TTL" cable variant which it
provides only 0-5V signalling. Further information is available here.
Maybe you have time to ask PilotAware if they can provide an RMC-only signal. Also called GPRMC without any other signals.
