Add-on channels to Futaba R/C

OVERVIEW: The KH712, KH716 and KH732

Hitchiker Radio Control systems combine Futaba's
excellent PCM1024 radio systems with VANTEC
KeyKoder technology to add the extra channels and

functions needed for Special EFX projects,
inspection/sample harvesting vehicles, and tele­operated robots. Great for controlling submarines
with their complex plumbing and pumps. Making
your dream scale R/C boat fully operational is now
easier than ever. Eliminate fussy servo­microswitch kluges. Microprocessor equipped
projects have used the Hitchiker channels to initiate
pre-programmed routines. Available on 72 or 75
MHz frequencies; there is no additional charge to
have your transmitter legal. VANTEC warrantees
the entire system.

The three systems are complete including the
Futaba FP7CAP series radio control sets and come
with transmitter, receiver, selection of servos, Nicad
batteries, charger and the VANTEC Hitchiker
KeyKoder components. The Futaba radio sets are
top-of-the-line models using Futaba's PCM1024
Pulse Code Modulation method. PCM is a
significant improvement over FM because it
transmits the servo commands as digital words with
special mathematical properties that facilitate
accurate reception and calibrated servo positions for
Fail Safe operation. Servo jitters are a thing of the
past. The F/S meets the criteria for competitive
robot safety shut-down. See the side panel for more
about the PCM Advantage.

VANTEC fully harnesses Futaba's coding to
reliably pack additional controls onto one of the
Futaba R/C servo channels. The new controls are
independent and operate simultaneously. The
remaining conventional channels are not affected.
To make a complete Hitchiker system VANTEC adds
two devices to the Futaba set.

The first device is a KeyPad that is added to the
transmitter. It mounts onto the base of the Futaba
FP-7CAP transmitter. Each new KeyPad channel is
actuated by a special toggle switch that can operate
momentarily like a push button by pressing down; it
automatically springs back to center off. Or switch
it "On" continuously like a normal toggle switch by
flipping it up. Any number of switches may be
activated at once. The KeyPad switches are labeled
1-16 or 1-32. The KeyPad understands and "speaks"
PCM1024; it interjects its new data onto one of the
regular servo channels through the trainer
connector. This means you lose the normal
operation of the selected channel; usually the
invisible 8th channel of the 7 channel system or the
"Retract" channel 5 is sacrificed.

The second device is a Receptor add-on box that
plugs into the Futaba R/C receiver like a servo and
separates the KeyPad commands back into 12, 16 or
32 individual outputs corresponding to the
transmitter KeyPad switches. The Futaba receiver is
optically isolated from the workings of the
Receptor. The Receptor has terminal blocks and

additional servo connectors
for the newly added
channels. These on-off or
two-state outputs manifest
themselves several ways
depending upon the
Receptor model. At 5A
capability each the ON-OFF
electronic switches can be
used directly for many
functions even with devices
operating on an assortment
of voltages. And the 8
conventional Servo Com­mand Pulse outputs are a
handy and familiar way to
implement mechanical
functions using conventional
servos.

The KH716 complete
system has 7 conventional
servo channels and 16
independent and
simultaneous KeyKoder
ON-OFF electronic switch
channels for 23 channels total. The first 8 of the 16
KeyKoder channels coincidentally features 2 three­position regular Servo Command Pulse outputs and
6 two-position regular SCP command outputs. The
KH716 system consists of: the complete Futaba
FP7CAP R/C set with the 7 channel FPR168DP or
other equivalent Futaba Brand receiver, VANTEC
KH16T KeyPad and KH16R Receptor and 2
servos. Additional servos available.

The KH732 complete system has 7 conventional
servo channels and 32 independent and
simultaneous KeyKoder ON-OFF switch channels
to yield 39 channels total. The first 8 of the 16
KeyKoder channels coincidentally feature 2 three­position regular Servo Command Pulse outputs, 6
two-position regular SCP outputs. The KH732
systems consists of: the complete Futaba FP7CAP
R/C set, with the 7 channel FPR168DP or
equivalent Futaba brand receiver, VANTEC
KH32T KeyPad and KH32R Receptor and 2
servos. Additional servos available.

Generally the ‘716 & ‘732 versions are employed in
boats and robots. Up to 128 ON-OFF channels can
be added to a single Futaba Servo Channel with an
array of KeyKoders.

The KH712 is specifically configured for model
aircraft applications. Switches 1 through 8 on the

KH16T KeyPad generate only Servo Command
Pulses and switches 13, 14, 15, and 16 are the only

electronic switch outputs on the KH12R Receptor.
The KH712 Hitchiker is perfect for 1/4 scale R/C
model airplanes with 7 conventional servo
channels for the normal flying functions and 12
added KeyKoder channels for a total of 19
channels. It's KeyKoder Receptor features 2 three­position regular Servo Command Pulse outputs, 6
two-position regular servo command outputs, and 4
electronic switches. Since the servo command
outputs are just like the signals coming from a
Futaba receiver you can plug-in up to 8 new
conventional servos for auxiliary functions like
bomb bay doors, bomb release, or parachutists. The
electronic switches can be used to control engine
ignition, starting, lights and camera. The KH712
system consists of Futaba FP7CAP PCM R/C set
with an 8 channel receiver, VANTEC KH16T
KeyPad and KH12R Receptor and Servos.

TRANSMITTER / KEYPAD INSTALLATION:
The KeyPad is factory mounted to the Futaba case,
a slight modification made to the transmitter. You
cannot use the original trainer feature after these
modifications.
