KEY, KEYER, AND COMPUTER-DRIVEN KEYING INTERCONNECTIONS

The FT DX 9000MP includes a host of features for the CW operator, the functions of which will be detailed in the “Opera-

tion” section later. Besides the built-in Electronic Keyer, two key jacks are provided, one each on the front and rear panels,

for convenient connection to keying devices.

The Menu system allows you to configure the front ane rear panel KEY jacks according to the device you wish to connect.

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 “straight key” for

connection purposes), and configure the rear panel jack using Menu #43.

Both KEY jacks on the FT DX 9000MP utilize “Positive” keying voltage. Key-up voltage is approximately +5V DC, and

key-down current is approximately 1 mA.

Advice

When connecting a key or other device to the KEY jacks, use only a 3-pin (“stereo”) 1/4” phone plug; a 2-pin plug will

place a short between the ring and (grounded) shaft of the plug, resulting in a constant “key-down” condition in some

circumstances.

CONNECTING A GPS RECEIVER

If you connect a properly-equipped after-market GPS re-

ceiver (not supplied) to the COM port on the back of the

transceiver, the “Rotator” page on the External display will

automatically include a Great Circle map centered on your

location.

Connect a GPS receiver capable of output of NMEA-0183

data to the COM port. The data line connects to Pin 2, and

the ground shield connects to Pin 5.

This transceiver can support the GGA, GLL, and RMC Data

Sentences from the GPS unit.
