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 “051 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 “053 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
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 “051 A1A F-TYPE” for paddle input,

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.

Interfacing to Other Linear Amplifiers
Note
The TX/RX switching in the linear amplifier is controlled by switching components
in the transceiver. The relay circuit of the FT-2000 used for this switching is
capable of switching AC voltage of 100 Volts at up to 300 mA, or DC voltages or 60
V at 200 mA or 30 V at up to 1 Amp. In order to engage the switching relay, use
Menu item “134 tGEn ETX-GND;” set this Menu item to “EnA (Enable)” to
activate the amplifier switching relay.
