Vertex Standard FT-1000MP manual Band Data DIN Jack, DC in Jack

REAR PANEL CONTROLS & CONNECTORS

10.PTT Phono Jack

This input jack may be used to provide manual trans- mitter activation using a footswitch or other switching device. Its function is identical to the [MOX] button on the front panel. The same line is available at the PACKET and RTTY jacks for TNC control. Open-cir- cuit voltage is +13.5 VDC, and closed-circuit current is 1.5 mA.

11.EXT ALC Phono Jack

17.+13.8V Phono Jack

This output jack provides regulated, separately fused 13.8 VDC at up to 200 mA, to power an external device such as a packet TNC. Make sure your device does not require more current (if it does, use a sepa- rate power source). Attempting to draw more power from here will blow the internal fuse behind this jack. Should this occur, replace the fuse (as explained on page 114).

This input jack accepts negative-going external ALC (Automatic Level Control) voltage from a linear ampli- fier, to prevent over-excitation by the transceiver. Ac- ceptable input voltage range is 0 to –4 VDC.

12.PATCH Phono Jack

This input jack accepts transmitter audio - either AFSK or voice - for transmission. This line is mixed with the microphone audio input line, so the microphone should be disconnected if using this jack and mixing is not desired. Impedance is 500 ~ 600 Ohms.

18.RX ANT Phono Jacks (In/Out)

These antenna jacks are provided for connection for a separate receive-only antenna, activated when the switch with the same name on the front panel is pressed. An antenna connected here can be used by both the Main and Sub Receivers.

19.TRV Transverter Drive Output Jack

This jack provides a low level RF output for use with a transverter. Maximum output is approximately 100 mVrms at 50 Ohms (–6 dBm).

13.EXT SPKR Mini Phone Jack

This 2-contact output jack provides mixed receiver audio for an external loudspeaker, such as the SP-8. Inserting a plug into this jack disables the internal loud- speaker. Impedance is 4 ~ 8 Ohms.

14.AF OUT Mini Phone Jack

This 3-contact jack provides dual-channel low-level receiver output, for recording or external amplification. Peak signal level is 100 mVrms at 600 Ohms. Main receiver audio is on the left channel (tip), and sub re- ceiver audio is on the right channel (ring). A stereo amplifier or recorder is recommended, to record each receiver’s audio separately when dual reception is en- abled. The front panel AF GAIN controls and the [AF REV] switch setting in the top access panel do not af- fect the signals at this jack.

15. GND Terminal Post

Use this terminal to connect the transceiver to a good earth ground, for safety and optimum perfor- mance. Use a large diameter, short braided cable.

16. BAND DATA DIN Jack

This 8-pin output jack provides control signals for the FL-7000/VL-1000Solid-State Linear Amplifier, in- cluding band selection data to automatically set the Linear or Tuner to the same band as the main display of the transceiver. Band Data jack connections are shown on page 4.

20. TX GND Jack (normally disabled)

When enabled by the [LIN] switch, this output jack connects inside the MARK-VFT-1000MPto a set of relay contacts which short together (to chassis ground) whenever the transmitter is active. This allows trans- mit/receive switching of an external device such as a linear amplifier. This jack is disabled at the factory, to avoid the clicking of the relay when it is not used.

Maximum ratings for these relay contacts are 500 mA @ 100 VAC, 200 mA @ 60 VDC or 1 A @ 30 VDC. Before connecting an external device, make sure its switching requirements will not exceed these limits. If your amplifier requires higher current, or has higher voltage switching requirements, an external switching device must be used.

21.LIN Linear Amplifier Relay Switch

To enable the TX GND jack when you are connect- ing a external linear amplifier, move this switch to its “ON” position.

22. DC IN Jack

Connect this 6-pin Molex socket to the Power Cable from the supplied FP-29AC Power Supply. This socket provides +30V DC, +13.8V DC, and control signals for the MARK-VFT-1000MP.
