SYSTEM OVERVIEW FLIGHT INSTRUMENTS EIS AAUUDDI&IOOCPN&ASCNENLS System Overview • GMU 44 (2) - The Magnetometer measures the local magnetic field and sends data to the AHRS for processing to determine aircraft magnetic heading. The magnetometer receives power directly from the AHRS and communicates with it via RS-485 and RS-232 digital interfaces. • GDL 69A - The Data Link Satellite Radio Receiver provides data link weather information, as well as digital audio entertainment and information. The Data Link Receiver communicates with the MFD via a HSDB connection. A subscription to SiriusXM Weather and/or SiriusXM Satellite Radio service is required to enable the GDL 69A capabilities. • GSR 56 (optional) - The Iridium Transceiver provides satellite-based communications. The GSR 56 receives data link weather products from the Garmin Connext Weather service through the Iridium satellite network. The transceiver also provides Short Message Service (SMS) text communications. The GSR 56 communicates with the #2 GIA through an RS-232 connection. • GTS 800 - The GTS 800 Traffic Advisory System (TAS) uses active interrogations of Mode S and Mode C transponders to provide traffic information to the pilot independent of the air traffic control system. An HSDB connection links the GTS 800 to the PFD. • GMC 720 - The AFCS Mode Controller provides AFCS control through an RS-232 digital interface with the PFD and MFD. • GSA 81 (2) and GTA 82 - The GSA 81 Servos are used for automatic control of pitch and roll. The GTA 82 Pitch Trim Adapter works with the existing motor to provide automatic pitch trim. These units interface with each IAU via RS-485 connections. • GSM 86 - The GSM 86 Servo Gearboxes (not pictured) are responsible for transferring the output torque of the GSA 81 servo actuators to the mechanical flight-control surface linkages. The Cessna T240 is also equipped with a GFC 700 Automated Flight Control System (AFCS), providing the flight director (FD), autopilot (AP), and manual electric trim (MET) functions to the system. NOTE: Refer to the Automatic Flight Control System (AFCS) Section for details on the GFC 700 AFCS. Figure 1-1 shows interactions between the LRUs. NOTE: For information on optional equipment shown in Figure 1-1, consult the applicable optional interface user's guide. This document assumes that the reader is already familiar with the operation of this additional equipment.
