DMX-Servo-Control 2 2
For your own safety, please read this user manual and warnings carefully
before installation.
Description
The DMX-Servo-Control 2 is designed for controlling of two servos via DMX.
Two Servos
The DMX Servo Control 2 has two servo ports. Each can be controlled via one DMX
channel.
Servos with 5V up to 12V DC can be used
The supply voltage of the DMX-Servo-Control 2 is between 5V and 12V.
Servos with a supply voltage within this range can be connected directly.
Adjustable Servo control signal
The controlling occurs via an adjustable pulse width.
Compact Design
The design and the compact construction allows an installation of this small
assembly in areas that do not offer much space.
LED-Display
The integrated LED is a multifunctional display for showing the current device status.
DMX Addressing
The DMX addressing is settable via a 10-position DIP switch.
RDM Support
The DMX Servo Control 2 allows configuration via RDM over DMX.

ATTENTION :
This DMX-Servo-Control 2 is NOT ADMITTED for applications whom has
safety-relevant requirements or in which dangerous situations can occur !

LED-Display
The integrated LED is a multifunction display.
During to the normal operation mode the LED lights permanently. In this case the
device is working.
Furthermore, the LED shows the current status. In this case the LED lights up in
short pitches and then is missing for longer time.
The number of the flashing lights is equal to the event number:

DMX-Addressing
The Start Address is adjustable via DIP-Switches.
Switch 1 has the valency 2
0
(=1), switch 2 the valency 2
1
(=2) and so on up to
switch9 with the valency 2
8
(=256).
The sum of the switches showing ON is equal to the start address.

The DMX start address can be also adjusted via the RDM parameter
DMX_STARTADDRESS. For RDM operation all switches must be set to OFF !

DMX-Servo-Control 2 7
Servo control signal
The signal which is send to the Servo consists of a High-Impulse and a Low one. The
pulse duration is important for the Servo.
Normally this impulse is between 1ms and 2ms, which is also the standard setting for
the DMX-Servo-Control 2. These are the end positions of the Servos where it is not
limited mechanically. A pulse length of 1.5ms would be the Servo middle position.
1,5ms
2ms (max)
1ms (min)
→Servo is positioned left
→Servo is positioned right
→Servo is positioned centred

DMX-Servo-Control 2 8
Adjust Servo control signal
In according to the used Servo it can be advantageous to adapt the impulse-times.
The minimum time for the left position can be set within the range 0,1-2,5ms. The
maximum time for the right position must be bigger than the minimum time and can
be maximum 2,54ms.
Please proceed as following for the settings:
-Turn on the DMX-Servo-Control
-Set DIP-Switch 9 and 10 on OFF
-Set DIP-Switch 10 on ON
-Set via the DIP-Switched 1-8 the Minimum time
-Set DIP-Switch 9 on ON
-Set via the DIP-Switched 1-8 the Maximum time
-Set DIP-Switch 10 on OFF
-The LED lights up 4x as confirmation that the settings are stored
-Set via DIP-Switches 1-9 the DMX-Starting address
The time-setting takes place with the DMX-Addressing via the DIP-Switches in 10µs
steps. Thereby the set value with 0,01ms is multiplied, so for example a value of 100
results in a value of 1ms.
1,00ms
= 100 x 0,01ms
2,52ms
= 252 x 0,01ms
1,01ms
= 101 x 0,01ms
2,53ms
= 253 x 0,01ms
1,02ms
= 102 x 0,01ms
2,54ms
= 254 x 0,01ms
The RDM parameters LEFT_ADJUST and RIGHT_ADJUST can also be used
to set the pulse time.

RDM
(from Hardware V2.1)
RDM is the short form for Remote Device Management.
As soon as the device is within the system, device-dependent settings occur remotely
via RDM command due to the uniquely assigned UID. A direct access to the device is
not necessary.
If the DMX start address is set via RDM, all address switches at the DMX-
Servo-Control 2 must be set to OFF ! A DMX start address set by the address
switches is always prior !
