can be used to operate devices connected to
the receiver (e.g. servos, speed controllers, etc.) for the purpose of
adjustment and testing, without requiring the use of the
transmitter and receiving system. For example, servos can be set
to their neutral position prior to fitting the servo output device;
after the servos have been installed in the model the unit can be
used as an easy means of adjusting the control surface neutrals
and travels.

In most cases the power supply is a 4-cell receiver battery (with
MPX connector), which is connected to the socket marked with
the battery symbol (see Fig. 1: BATT socket).
Alternatively a receiver battery with UNI connector can be
connected to either of the UNI sockets (see Fig. 1: UNI1 and
UNI2).

The rotary knob which is used to operate or control the unit
manually features a graduated scale: 0 % / 50 % / 100%.
The 100 % values correspond to full travel of the radio control
transmitter, and 0 % equates to the neutral or centre position.
The unit generates the following signals (pulse widths) according
to the set value and the socket in use:

MULTIPLEX devices fitted with the MPX connector system
generally exploit the MPX signal format, and should be connected
to the MPX sockets (exception: MULTIPLEX MS-X series servos.
Units with UNI connectors, and units made by other
manufacturers, should be connected to the UNI sockets.

The test-run is designed to control servos or other units
automatically and continuously for the purposes of testing or
demonstration. The unit runs from one selectable position to
another and back again with variable speed.:
1. Set any Position 1 using the rotary knob.
2. Press the “SET” button to store the position.
3. Set any Position 2 using the rotary knob.
4. Press the “SET” button to store the position.
Press the START/STOP button to start and stop the test-run
process. You can vary the speed at any time by turning the rotary
knob
(- 100 % = slow, + 100 % = fast).

The SERVO-Master can be used to reverse the direction of
rotation of MULTIPLEX “digi” servos. This may be necessary, for
example,
• if the transmitter does not feature a servo reverse facility; or
• if two servos are connected to one channel using a Y-lead,
and the direction of rotation of one servo needs to be
changed.
To do this connect the servo to a socket (UNI1 or 2, or MPX 1 or
2) as described in Section 5, and connect the power supply as
described in Section 4.
To reverse the direction of servo rotation:
1. Press and hold the “SET” button,
2. Press the “START/STOP” button and hold it briefly, then
3. Release both buttons again.
When you release the buttons the direction of servo rotation is
reversed, and the direction is stored permanently in the servo’s
memory. The servo direction can be reversed again at any time. If
the rotary knob is not at centre (= 0 %) when you reverse the
servo, you can check the change immediately: the servo
immediately moves to the same position on the opposite side of
neutral.
