The FT-2000 includes a host of features for the CW operator, the functions of which will be detailed in the “Operation”
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 and 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 item “052 A1A F-TYPE” 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 item “054 A1A R-TYPE.”

Both KEY jacks on the FT-2000 utilize “Positive” keying voltage. Key-up voltage is approximately +5V DC, and key-
down current is approximately 1 mA. 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.
