Be sure that both the FT-450D and VL-1000 are turned off, then follow the installation recommendations con-
tained in the illustration.

The T/R control line is a transistor “open collector” circuit, capable of handling positive amplifier relay coil volt-
ages of up to +50V DC and current of up to 400 mA. If you plan on using multiple linear amplifiers for different
bands, you must provide external band-switching of the “Lin Tx” relay control line from the “TX GND OUT” line
at the LINEAR jack.
ages of up to +50V DC and current of up to 400 mA. If you plan on using multiple linear amplifiers for different
bands, you must provide external band-switching of the “Lin Tx” relay control line from the “TX GND OUT” line
at the LINEAR jack.
Important Note!
Do not exceed the maximum volt-
age or current ratings for the “TX
GND OUT” line at the LINEAR jack.
This line is not compatible with
negative DC voltages, nor AC volt-
ages of any magnitude.
Most amplifier control relay systems
require only low DC voltage/current
switching capability (typically, +12V
DC at 25 ~ 75 mA), and the switch-
ing transistor in the FT-450D will eas-
ily accommodate such amplifiers.
To link the FT-450D and VL-1000
Power switches, set the VL-1000 RE-
MOTE switch to the “ON” position.
