is a general-purpose servo tester, and

programming unit for MULTIPLEX "digi" servos. The unit provides

the following facilities:

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.

A special feature is the automatic test

OWER SUPPLY

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:

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.:

2. Press the "SET" button to store the position.

3. Set any Position 2 using the rotary knob.

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

ROGRAMMING UNIT FOR

ROGRAMMING UNIT

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.
