2 Safety Notes

This unit corresponds to the directive for electromag-
netic compatibility 89/336/EEC and to the low volt-
age directive 73/23/EEC.
Attention!
The unit is supplied with hazardous mains voltage
(230 V~). Leave servicing to skilled personnel only.
Inexpert handling may cause an electric shock haz-
ard. Furthermore, any guarantee claim will expire if
the unit has been opened.
Please observe the following items in any case:
The unit is suitable for indoor use only. Protect it
against dripping water and splash water, high air
humidity, and heat (admissible ambient tempera-
ture range 0 – 40 °C).
Do not place any vessel filled with liquid on the unit,
e. g. a drinking glass.
Do not operate the unit or immediately disconnect
the plug from the mains socket
1. if there is visible damage to the unit or to the
mains cable,
2. if a defect might have occurred after the unit was
dropped or suffered a similar accident,
3. if malfunctions occur.
In any case the unit must be repaired by skilled per-

Important for U. K. Customers!
The wires in this mains lead are coloured in accord-
ance with the following code:
blue = neutral
brown = live
As the colours of the wires in the mains lead of this
appliance may not correspond with the coloured
markings identifying the terminals in your plug, pro-
ceed as follows:
1. The wire which is coloured blue must be con-
nected to the terminal in the plug which is
marked with the letter N or coloured black.
2. The wire which is coloured brown must be con-
nected to the terminal which is marked with the
letter L or coloured red.
3 Applications
The units SR-103DMX and SR-105DMX are specially
designed for application in DMX-controlled lighting
systems. They serve to split DMX control signals or to
amplify signals in case of long control cables. Model
SR-103DMX is equipped with 3-pole XLR connectors and model SR-105DMX with 5-pole XLR connectors.
The inputs and outputs are DC separated by opto-
electronic couplers.

4 Setting into Operation

All connections should be made by skilled personnel
only. Fig. 3 shows an example for connection.
1) Feed the DMX control signal to the XLR input DMX
IN (3).
For connection, it is recommended to use spe-
cial cables for high data flow. Use of standard mi-
crophone cables is recommended only for a maxi-
mum cable length of 100 m. The best transmission
quality is obtained with a screened microphone ca-
ble of 2 x 0.25 mm 2 or a special data transmission
cable. For cable lengths equal to or greater than
150 m, it is recommended to insert the SR-103
DMX or the SR-105DMX as a signal amplifier into
the DMX signal line.
2) Connect in each case the jacks DMX OUT (4)
to the DMX input of the next DMX-controlled
units. The jacks DMX OUT are provided with a
latching device. To remove a plug, press the PUSH
lever.
3) Finally connect the mains plug of the connection
cable (1) to a mains socket (230V~/50 Hz). After
that, the unit is ready for operation and the POW-
ER LED (2) lights up.
To switch off, disconnect the plug from the
socket.
