XTBA SMART SPLITTER 10i
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.
SYSTEM OPERATION
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.
