ROT
(
ROTATOR
)
Jack
This 5-pin MINI-DIN Jack accepts a cable connected
to a YAESU G-800DXA/-1000DXA/-2800DXA An-
tenna Rotator (listed models are current as of early
2006). You may control the antenna azimuth rotation
(and rotation speed) using the Function buttons on the
front panel.
BND
(
BAND
)
DATA Jack
This 8-pin output jack provides band selection data
which may be used for control of optional accessories
such as the VL-1000 Solid-state Linear Amplifier.
PACKET Jack
This 5-pin input/output jack provides receiver audio
and squelch signals, and accepts transmit (AFSK) au-
dio and PTT control, from an external Packet TNC.
Pinout is shown on page 15. The receiver audio level
at this jack is approximately 100 mVp-p (@600 Ohms).
RTTY Jack
This 4-pin input/output jack provides connections for
an RTTY terminal unit. Pinout is shown on page 15.
The receiver audio level at this jack is at a constant
100-mV (@600 Ohms) level. FSK keying at this jack
is accomplished by a closure of the SHIFT line to
ground by the terminal unit.
PTT Jack
This RCA input jack may be used to provide manual
transmitter 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-
circuit voltage is +13.5 VDC, and closed-circuit cur-
rent is 5 mA.
MIC
(
PATCH
)
Jack
This RCA input jack accepts transmitter audio - either
AFSK or voice - for transmission. This line is mixed
with the microphone audio input line, so the micro-
phone should be disconnected if using this jack and
mixing is not desired. The optimum impedance is 500
~ 600 Ohms, and the nominal input level should be 5
mV.
TRV Jack
This RCA jack provides a low level RF output for use
with a transverter. Maximum output is approximately
–10 dBm (0.1 mW) at 50 Ohms.
REC Jack
This RCA jack provides low-level receiver audio out-
put and transmit audio, for recording or external am-
plification. Peak signal level is 30 mVp-p at 10 kOhms.
EXT ALC Jack
This RCA input jack accepts negative-going external
ALC (Automatic Level Control) voltage from a linear
amplifier, to prevent over-excitation by the transceiver.
Acceptable input voltage range is 0 to –4 VDC.
