Appendix D Overview GPS Navigation Flight Planning Hazard Avoidance Additional Features CONNECTING TO A GTX 330 MODE S TRANSPONDER To receive Mode S TIS traffic data from a GTX 330 transponder on your aera 795/796, connect an available RS-232 OUT wire on the transponder to the Data In wire on the aera 795/796. (You do not need to connect the transponder to the aera's Data Out wire.) Then, set the corresponding RS-232 output configuration on the transponder to REMOTE + TIS and set the aera's Serial Data Format to TIS In or TIS In/NMEA & VHF Out. For more information, see the GTX 330 Transponder Installation Manual. Configuring TIS input: 1) Connect the aera 795/796 to the GTX 330 using the Aviation Bare Wire Connector (optional accessory). 2) From the Main Menu, touch Tools > Setup > Interface. 3) Touch the 'Serial Data Format' datafield button. A vertical list is displayed. 4) Touch 'TIS In' or 'TIS In/NMEA & VHF Out'. The TIS Status field indicates one of the following messages: • Waiting For Data-searching for a valid TIS data stream. • Data Available-receiving TIS data from the transponder. • Data Unavailable-connection to transponder established, but TIS service is unavailable. • Lost Connection-an error occurred or the connection to the transponder was lost.
