Vertex Standard FT-1000MP Manual Do Utilizador

Construct a patch cable or cables to make the nec-

essary connections between your TNC and the appro-
priate rear panel jack(s) (RTTY for FSK, PACKET for
AFSK). Refer to the pin-out diagram below, and the
wiring instructions included with your TNC. A descrip-
tion of the PACKET jack’s individual pins follows:

Pin 1 (DATA IN) - Connect this pin to your TNC’s

“AFSK Out” or “Mic Audio” output line. The optimum
input level is 30 mV rms, and the input impedance is 3
k

Ω

. Your TNC’s audio output level potentiometer will

allow you to set the level to the optimum value. This
pin may be used either for 300 baud SSB-mode digital
operation or for 1200-baud FM packet. The bandwidth
and frequency response are not, however, suitable for
9600 baud operation.

Pin 2 (Ground) - Connect this to the shield(s) of

the cable(s) used for connections between the TNC
and the MARK-V FT-1000MP.

Pin 3 (PTT) - Connect this pin to the PTT line from

the TNC. This pin, when grounded by the TNC, places
the MARK-V FT-1000MP into the Transmit condition.

Pin 4 (DATA Out) - Connect this pin to your TNC’s

“RX Audio” input line. This is a constant-level (100 mV
rms @ 600 

Ω

) audio output line which is not affected

by the position of the front-panel AF GAIN control.

Pin 5 (BUSY) - This is a “Squelch Status” pin not

generally required for digital mode operation. This pin
is held at +5V when the squelch is open, and is
grounded when the receiver is muted by the squelch
(“no-signal” condition).

For FSK operation using the RTTY jack, the fol-

lowing are the pin connections required:

Pin 1 (SHIFT) - Connect this pin to your TNC or

terminal unit’s “FSK Key” port. Closing and opening of
this line to ground causes mark/space keying.

Pin 2  (RX AF OUT) - Same as “DATA OUT” on

PACKET jack.

Pin 3 (PTT) - Same as “PTT” on PACKET jack.

Pin 4 (GND) - Same as “GND” on PACKET jack.

For operation on PSK31, connect your computer's

sound card to the PACKET jack (for “PKT” mode op-
eration) or the MIC and EXT SP jacks (for “SSB” mode

menu selection 8-6 to configure

the "User" mode (see page 110) for PSK31 operation.

For most operation, you will want to use the PS31-

U (for PKT mode) or PS31-SU (for USB mode) op-
tions under “East Set;” while BPSK operation is not
sideband-sensitive, QPSK operation, by convention,
utilizes USB-side injection.

The “User” mode is accessed, during operation, by

pressing and holding in for ½ second the [PKT] mode
switch.
