Plugging in the Servos
Plug the servo leads into the appropriate ports in the PowerSafe. You are now
ready to bind the system.
IMPORTANT: When using Y-harnesses or servo extensions, it’s important
to use standard non-amplified Y-harnesses and servo extensions as this can/
will cause the servos to operate erratically or not function at all. Amplified
Y-harnesses were developed several years ago to boost the signal for some
older PCM systems and should not be used with Spektrum equipment. Note
that when converting other models to Spektrum be certain that all amplified
Y-harnesses and/or servo extensions are replaced with conventional,
non-amplified versions.
The JR PCM Y-Harness with Amplifier (JRPA133) is not compatible with the
AR12120 and should not be used.
Binding
NOTICE: In order for the system to operate, one remote receiver must be
plugged into receiver port A and two more receivers must be plugged into
any other ports. When binding the PowerSafe with three remote receivers, if a
fourth remote receiver is added, the system must be re-bound to recognize the
additional remote.
It’s necessary to bind the AR12120 to the transmitter so that the AR12120 will only
recognize that specific transmitter, ignoring signals from any other sources. If the
PowerSafe is not bound to the transmitter, the system will not operate. During
binding, the servo’s failsafe positions are stored.
How To Bind the PowerSafe
1. With the system hooked up and all remote receivers attached as described
previously, insert the bind plug in the BIND/DATA port in the PowerSafe.
2. Turn on the soft switch. Note that the LEDs on all receivers should be flashing
indicating that the receivers are ready to bind.
3. Establish the desired failsafe stick positions, normally low throttle and flight
controls neutral.
4. Follow the procedures of your transmitter to enter it into bind mode. The system
will connect within a few seconds. The LEDs on all receivers should go solid,
indicating the system has connected.
5. Remove the bind plug and store it in a convenient place.
6. After you’ve programmed your model, it’s important to rebind the system so the
true low throttle and neutral control surface positions are programmed.
