FT-950

Operating Manual

Note:

Please refer to the VL-1000 Operating Manual for details regarding amplifier operation.

Please do not attempt to connect or disconnect coaxial cables when your hands are wet.

About the CONTROL Cable

The VL-1000 may be operated with the FT-950 whether or not the CONTROL Cable is connected; however, the CONTROL Cable allows you to tune up the amplifier automatically by just pressing the [F SET] or [TUNE] key on the VL-1000, so as to transmit a carrier for tuning purposes.

Set the front panel’s INPUT switch to the “INPUT2”.

To link the FT-950 and VL-1000 Power switches, set the VL-1000 REMOTE switch to the ON position.

Interfacing to Other Linear Amplifiers

The TX GND OUT pin (pin 2) of the LINEAR jack is a transistor “open collector” circuit, capable of handling positive amplifier relay coil voltages of up to +60VDC at 200 mA or +30 VDC at 1 A. If you plan on using multiple linear amplifiers for different bands, you must provide external band-switching of the “Linear Tx” relay control line from the “TX GND OUT” line at the LINEAR jack.

Important Note!: Do not exceed the maximum voltage or current ratings for the “TX GND OUT” pin (pin 2) of the LINEAR jack. This line is not compatible with negative DC voltages, nor AC voltages 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 switching transistor in the FT-950 will easily accommodate such amplifiers.

Plug/Connector Pinout Diagrams

IMPORTANT NOTE:

The μ-TUNE and DMU connectors are special connectors for this transceiver. Please do not connect any accessory or other device not specifically approved by Vertex Standard. Failure to observe this precaution may cause damage not covered by the Limited Warranty on this apparatus.
