GTX 330/330D units are stand alone, panel mounted units that operate through the integrated display.
GTX 330/330D units can be controlled by an external control unit such as the GTN 6XX/7XX or the
GNS 480. They can display TIS-A information on an approved display unit, via an RS-232 digital
interface.

degraded ADS-B system.
GTX 330/330D units communicate through the following interfaces.
 ARINC 429
 RS-232
