Rear Panel - Yaesu FT dx 1200 Operating Manual

ANT 1/2 Jacks
Connect your main antenna(s) here, using type-M
(PL-259) connectors and coaxial feed lines. The in-
ternal antenna tuner affects only the antenna(s) con-
nected here, and only during transmission.
Warning!
The 100V RF voltage (@100 W/50 Ω) is applied to
the TX RF section of the transceiver while trans-
mitting. Do not touch the TX RF section while
transmitting.
DC IN Jack
This is the DC power supply connection for the
transceiver. Use the supplied DC cable to connect di-
rectly to a DC power supply, which must be capable
of supplying at least 23 A @13.8 VDC.
GND
Use this terminal to connect the transceiver to a good
earth ground, for safety and optimum performance.
Use a large diameter, short braided cable for making
ground connections, and please
other notes about proper grounding.
To prevent damage from
spheric electricity, electrical shock, etc., be
certain to provide a good earth ground.
µ-TUNE Jacks
These jacks are used to connect the optional RF
µTuning Kit, signal in and signal out.

ROT Jack
This covered 6-pin MINI-DIN Jack accepts a cable
to connect to a YAESU G-800DXA/-1000DXA/
-2800DXA Antenna Rotator (listed models are cur-
rent as of early 2013). You may control the antenna
azimuth rotation (and rotation speed) using the Func-
tion buttons on the front panel.
LINEAR Jack
This 10-pin output jack provides band selection data,
which may be used for control of optional accesso-
ries such as the VL-1000 Solid-state Linear Ampli-
fier.
TUNER Jack
This 8-pin output jack is used for connection to the
FC-40 External Automatic Antenna Tuner.
RTTY/DATA Jack
This 6-pin input/output jack accepts AFSK input
from a Terminal Node Controller (TNC) or an op-
tional interface unit; it also provides
mV @600 Ohms) receiver audio output, and FSK
keying line.
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 RTTY/PKT jack for TNC control.
Open-circuit voltage is +5 VDC, and closed-circuit
current is 2 mA.
