I having a Skytrax 100 installed, and the avionics shop reports that The current encoder installed in the aircraft is not compatible with the Skytrax Serial Altitude input needed so we will need to replace the existing encoder with a unit that is capable of outputting serial altitude data. The blind encoder was installed in 2013, it is a Transcal model SSD120-30N. I checked before installing this model if it would be compatible with the IFD-540, and it was. I'm surprised that the encoder would not be compatible with the Skytrax 100. Can anyone enlighten me? TIA

The link is for install manual, you can check Appendix D for encoder compatibility http://www.navworx.com/documents/TSO%20ADS600-B%20Installation%20Manual%20240-0008-00-39.pdf

Do you have an AXP340 installed? ------------- Simpson Bennett Avidyne Corporation Product Manager |

| Your encoder only has a gray code (parallel) output. The IFD-540 can accept either RS-232 serial or gray code (parallel) input, so your encoder will work with the IFD-540. I suspect the Skytrax 100 requires a RS-232 signal which your encoder doesn't have. |

The IFD540 can also accept 429 altitude data. If an AXP340 is installed you can use the altitude output from pin 6. ------------- Simpson Bennett Avidyne Corporation Product Manager |
