Direct Servo Control (DSC)
For proper DSC hook-up and operation:
1. Leave the transmitter power switch in the “off” position.
The transmitter will not transmit any radio frequency (
RF) in this
position.
2. Plug the
DSC cord (supplied) into the DSC
port in the rear
of the transmitter.
3. The encoder section of the transmitter will now be opera-
tional and the
LCD display will be lit.
4. Plug the other end of the
DSC cord into the receiver charge
receptacle. Turn the switch harness to the “on” position.
Note: When installing the switch hareness charging jack, be
sure to hook the
charging jack receptacle
, JRPA024,
securely into
the switch harness charge cord.
Why you should use the DSC function:
1. The DSC
enables you to check the control surfaces of your
helicopter without drawing the fully operational 200ma from
your transmitter battery pack. Instead, you will only draw
70ma when using the
DSC function.
2. The
DSC function allows you to make final adjustments to
your helicopter without transmitting any radio signals. Therefore,
if another pilot is flying on your frequency, you can still adjust
your helicopter and not interfere with the other pilot’s aircraft.
Note: Under no circumstances should you attempt to fly your
helicopter with the DSC cord plugged in! This feature is for
bench checking your helicopter only.
Frequency Notes
The PCM10X employs a plug-in module system for transmitter
frequency changes. If you wish to change a frequency, you can
simply change the radio frequency (
RF) module, commonly
referred to as either an
RF module or transmitter module. The JR
modules are universal for all of the modular frequency controlled
systems. In other words, if you currently own a modular JR sys-
tem, you can use the
RF module from your current system with
the new
PCM10X.
The
PCM10X can transmit in either pulse code modulation (PCM
)
or in pulse position modulation (
PPM). Be certain to observe the
following guidelines:
1. Do not operate your transmitter when another transmitter is
using the same frequency, regardless of whether the second
transmitter is
PCM, PPM, AM or FM. You can never operate two
transmitters on the same frequency simultaneously without caus-
ing interference to both receivers and crashing both aircraft.
2. For operation of your
PCM10X with additional receivers, you
should refer to the receiver compatibility chart. The chart is
located in Section 8.25 of this manual.
Aircraft Only Frequencies
JR RF modules and receivers are available in 50, 53 and 72 MHz
frequencies in the United States for use with model aircraft.
Employing 72 MHz frequencies does not require a special opera-
tor’s license from the Federal Communications Commission
(FCC). However, the 50 and 53 MHz frequencies require that
you carry a Technician no code II license.
• A chart for all available frequencies is located in Section 14
of this manual.
