The XTBA SMART SPLITTER 10i is a single input ten output data distribution isolation amplifier, designed for use with lighting/moving light controls using USITT DMX512 (1990/1986) protocol. In addition to the ten buffered and fully isolated outputs the unit also has a data loop through so in the event of power failure data will still pass through the unit. Power for the unit is via a fused Euro chassis plug and mating socket.

DISPLAYS

The Smart Splitter 10i will display the following.

MAINS ON SWITCH will be lit when the unit is powered and switched on.

POWER ON via the red led. Show that the on board power supply is active.

DATA active via the green LED. In normal operation the data led may flash as it detects the data breaks. Slow data or long breaks will also make the data led flash. The data led tells you their is something happening on the line. It will not tell you if the data is good or indeed DMX512.

LOOP THROUGH and TERMINATION

The DATA THROUGH  XLR is a retransmitted and buffered copy of the DATA IN input. The DATA IN connector is fully terminated when the unit is powered. In the event of power failure the termination and re-buffering system is disconnected and data is passed directly through the DATA IN to the DATA THROUGH.

Looped through data can also be taken from any of the ten isolated outputs, gaining the isolation, but data will be lost in the event of power failure.

DATA OUTPUTS

Each of the ten data outputs is fully isolated from the input and the other nine outputs. In addition the output is protected against AC or DC voltages coming back onto the DMX line from other sources such as scroller power supplies and sad attempts to soldier an XLR extension cable correctly.

POWER SUPPLY

The mains input to the transformers is via a 2A a/s fuse and the transformer may be switched to 120 volt operation via the internal PCB mounted selection switches. A spare fuse is provided in the input connector block on the rack unit.

19” RACK MOUNTING

The rack version of the XTBA Smart Splitter 10i is provided with a pair of ‘ears’ for fitting into a 19” rack frame. The ears are fitted to the unit by removing the two screws on either side at the front of the unit. The stick on rubber feet (used when the unit is free standing) will need to be removed from the underside of the unit.
