Besides the built-in Electronic Keyer, two key jacks are provided, one each on the front and rear panels, forconvenient connection to keying devices.The Menu selections below, allow you to configure the front ane rear panel KEY jacks according to the device you wish toconnect. For example, you may connect your keyer paddle to the front panel KEY jack, and use Menu #41 for paddle input,while connecting the rear panel’s KEY jack to the keying line from your personal computer (which emulates a “straightkey” for connection purposes), and configure the rear panel jack using Menu #43.Both KEY jacks on the FT DX 9000 utilize “Positive” keying voltage. Key-up voltage is approximately +5V DC, and key-down current is approximately 1 mA.AdviceWhen connecting a key or other device to the KEY jacks, use only a 3-pin (“stereo”) 1/4” phone plug; a 2-pin plug willplace a short between the ring and (grounded) shaft of the plug, resulting in a constant “key-down” condition in somecircumstances.Pin 2GPS DATA INPin 5GNDCONNECTING A GPS R ECEIVERIf you connect a properly-equipped after-market GPS re-ceiver (not supplied) to the COM port on the back of thetransceiver, the "Rotator" page on the TFT display will au-tomatically include a Great Circle map centered on yourlocation.Connect a GPS receiver capable of output of NMEA-0183data to the COM port. The data line connects to Pin 2, andthe ground shield connects to Pin 5.This transceiver can support the GGA, GLL, and RMC DataSentences from the GPS unit.
