Splitter/Booster SP12

DMX512 Splitter/ Booster 1 in 2

The SP12 is a DMX512 interface splitter and booster. The DMX signal that needs to be boosted is connected to the input IN on the rear side of the unit and can be forwarded to the THRU socket. IN and THRU have a 5-pole connection.

On the front side, there are two DMX512 outputs with a total electric isolation from each other and from the input signal (optocouplers).

Also on the front side are two LEDs: one indicating the operating status (red) and one for the DMX512 input (green). If there is no correct DMX signal available (real evaluation), the green LED will flash.

Interface connector lines like DMX512 have to be electrically terminated with a corresponding resistor. If the SP12 is the last unit in a DMX line, a terminating resistor can be activated via the TERMINATE switch.

! Important: do not turn on the terminating resistor when using the THRU output.

The interfaces have a galvanic isolation and use standard RS485 components for sending and receiving. A 160mA delay-action fuse of the type TR5 is installed.
