Enigma/Odyssey installation manualOdyssey specific connectors2425231. USB host connectorsThese connectors are used to connect a master panel to a slave panel. The masteris always the host so the host connector of the master connects to the USB deviceconnector of the slave. Note: The connections you choose here determines whichpanel is master and which is slave – no further setup for this is required. Pleasenote that some slave panel options may need to be setup in the instrument setup.You can connect up to two slaves to a single master panel. The USB hostconnector is also used to connect a communications extender module1. USB device connectorThis connector connects to a master panel or a PC application capable ofcommunicating with the instrument through USB such as flight simulators2. RS232 Port 1This multifunction port is typically used to connect NAV and COM radios orXRX/PCAS or FLARM traffic monitoring systems.3. RS232 Port 2 / NMEAThis port is a dedicated NMEA output containing GPS messages intended for yourautopilot or GPS enabled application. Baudrate is 4800 (Enigma) and 9600(Odyssey).Odyssey only: The RX of this port can receive NMEA from an external GPS if this isselected in the instrument setup. External NMEA must be selected at 9600 baud.4. GPS AntennaThis SMA connector accepts connection of an active GPS antenna. Active GPSantennas contain a built in amplifier. Supply voltage on this connector is 3.3V. Theoutput is short circuit protected. A short circuit will switch off the supply voltage. Theinstrument needs to be restarted to switch the supply on again.5. Secured supply outputThese two terminals provide power to AHRS, compass sensor, RDACs and IOExtender. This power is switched to the battery backup (if fitted). Observe maximumcurrent capability of his output. Over current or shorting this output may damage thePage 4
