6. THE GTX 330 ARINC 429 OUT 2 PORT IS HIGH-IMPEDANCE WHEN THE EXTERNAL STANDBY SELECT INPUT IS
GROUNDED. THIS ALLOWS ARINC 429 OUTPUTS FROM DUAL GTX 330 UNITS TO BE HARD-WIRED TOGETHER SINCE THE
EXTERNAL STANDBY SELECT INPUT WILL BE ACTIVE FOR ONE OF THE TWO GTX 330’S AT ANY GIVEN TIME.
8. THE GTS PROCESSOR IS NOT TO BE INSTALLED IN AN AIRCRAFT WITH A TSO-C119a-ONLY COMPATIBLE TRANSPONDER.
