Introduction The DMX splitters of the ISP-4/ISP-6 line of products boost an incoming DMX signal and provide it on four/six output ports. This allows for connecting more than the 32 devices allowed according to ANSI E1.11 to a single universe, as well as for building star topologies.

ISP Block Diagram ISP-6R models: ISP-4R models: PSU Connection A suitable power supply unit that meets the following conditions, must be supplied by the user: • Stabilized DC output voltage: 10 V - 48 V • Power: 4 W (ISP-4), 6 W (ISP-6) See page 8, item 1, “power input”.

The DMX standard ANSI E1.11 suggests that transmitters are “ground referenced”. With the ISP-4/ISP-6, this is achieved for each output port by wiring pin 3 to pin 4. In some cases, however, the above configuration may lead to so called ground loops. This applies when a DMX receiver’s COM input signal is connected to the earth with a low resistance.
Line Termination The line termination of the ISP-4/ISP-6 splitters may be turned on or off using the toggle button next to the through port. See page 8. The line termination should be turned on by pushing it down when no receiver is connected to the through port of an ISP-4/ISP-6, and turned off otherwise.
