GPS. The Sport SX EFIS display units have two model numbers. The S200 is used as the primary flight display (PFD) in a multi-display system, or the only display in a single- display system. -
Page 9: 1-4: Integrating Third-Party Equipment
S200 should be used in place of the S100. An internal GPS is standard in the Sport SX S200. Any external GPS may also be used, as long as its serial data output is in one of the commonly used avionic formats. Most GPS units will always transmit their flight plan, allowing the EFIS to display either the GPS’s flight plan or its own internal plan. -

Page 13: 2-2: Common Equipment Interfaces
EFIS exceeds the standard. • The Sport SX serial ports are all high-speed, meaning that any serial port can be used with any device, regardless of the baud rate the connection may require. The Legacy Sport WS and HS models have a single high-speed port (serial port 4), which is typically used to provide ADS-B weather or XM weather to the EFIS. -
Page 14: 2-2-2: Autopilots
2-2-3: Autopilot Using GRT Avionics Servos An autopilot using GRT Servos provides excellent performance and is the easiest configuration to implement. The installation will require wiring for the servos, mounting kits to attach the servos to your airplane, a power-switch for the servos and an engage/disengage button. -
Page 15: 2-2-5: Ads-B Receivers
2-2-6: ADS-B GPS Output The GPS output from the Sport SX’s internal GPS is NOT FAA 2020 compliant for use with ADS-B or mode S with extended squitter transponders. If this GPS position data is used, the FAA will detect that a noncompliant GPS is being used. However, the GRT Safe-Fly GPS is 2020 ADS-B compliant and is approved by the FAA for this use. -
Page 16: 2-2-9: Communication And Navigation Radio Tuning
GRT Avionics, Inc. May 2019 data. The Sport SX requires an external adapter for Gray code altitude encoding outputs. Newer transponders may allow either serial output or Grey code. 2-2-9: Communication and Navigation Radio Tuning The EFIS has the ability to load the Garmin SL30 and SL40 radios with frequency pre- sets, allowing convenient selection of these frequencies from the front panel controls of the radio. -
Page 17: 2-3: Gray Code Altitude Encoder Output
A USB port is easy to connect and transmits large amounts of data quickly. USB devices do not require you to program a baud rate. The Sport SX has one USB port that may be used for one USB device. Alternatively, you may attach a USB hub to connect up to three devices. -
