Direct Servo Control - GRAUPNER MX-12 - PROGRAMMATION Manual

Direct servo control (DSC)
9. The left side of the right-hand assembly has a metal
strip which provides the ratched friction action. This
is held in place by two screws. Undo the screws and
transfer the metal strip to the left-hand assembly.
10. The mechanical conversion is now completed; check
the stick actions are as required and reassemble the
transmitter by reversing the above process, not for-
getting to plug in the multipin connectors.
Frequency notes
The mx-12 can transmit in either Pulse Code Modulation
(PCM) or Pulse Position Modulation (PPM, commonly
referred to as FM):
Be certain to observe the following guidelines:
Do not operate your transmitter when another transmit-
ter is using the dame frequency, regardless of whether
the second transmitter is PCM, PPM (FM) or AM. You
can never operate two transmitters on the same fre-
quency simultaneously without causinf interference.
For proper DSC hook-up and operation:
1. Leave the transmitter power switch in the OFF posi-
tion. The transmitter will not transmit any radio fre-
quency (RF) in this position.
2. Plug the (supplied) DSC cord into the DSC port in
the rear of the transmitter.
3. The encoder section of the transmitter will now be
operational 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 you install the charging jack, be sure to
hook the charging jack receptable 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 aircraft without drawing the fully operational
200mAh from your transmitter battery pack. Instead,
you will only draw approximately 70mAh when using
the DSC function.
2. The DSC function allows you to make final adjust-
ments to your airplane without transmitting any radio
signals. Therefore, if another pilot is flying on your
frequency, you can still adjust your aircraft and not
interfere with the other pilot`s aircraft.
Note: This function is for bench-checking your airplane
only.
