Horizon Hobby JR DSM 12X, Instruction And Programming Manual, Page: 17 / 192

Binding is necessary to program the receiver to the transmitter
so that the receiver will only recognize that specific transmitter,
ignoring signals from any other sources. If the receiver is not
bound to the transmitter, the system will not operate. During
binding, the servo’s failsafe positions are stored.
The following sequence describes the binding procedure for the
JR1221, however, all JR and Spektrum DSM aircraft receivers
are bound in the same way.
1. With the system hooked up as shown, insert the bind plug
in the charge plug receptacle. The switch must be a 3-wire
type switch (JRPA001 or JRPA004) to enter the bind mode
through the switch. If a 3-wire switch is not available, install
the male bind plug directly into the receiver bind/data
receptacle and power the receiver through any other open
port to enter the bind mode.

2. Turn on the receiver switch. Note that the LED’s on all
receivers should be flashing, indicating that the receiver is
ready to bind.

3. Establish the desired failsafe stick positions: normally low
throttle and flight controls neutral.
4. Press and hold the bind button on the back of the transmitter
while turning on the power switch. The bind button should
flash and within a few seconds the system should connect.
The LED’s on the receivers should go solid, indicating the
system has connected.
5. Remove the bind plug from the receiver or switch harness
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.
Note : To bind an aircraft with an electronic speed
controller that powers the receiver through the throttle
channel (BEC), insert the bind plug into the bind/data port
and proceed to Step #2.
