The XTBA Smart Switch 8:4 is designed to allow one to four universes of DMX to
have an on line back up that will detect data failure and switch to the back up data.
Additional units can be slaved for a greater number of universes.
OPERATION
On power up the Smart Switch will sequence the LED’s on the front panel on
automatic mode. In manual mode (see below) the LED’s will all light for 0.5 sec.
This tests the LED’s and the systems micro controllers.
The main control desk inputs are connected to the relevant universe ‘main in’ and
the back up universe to ‘back up’ – easy so far. Each input is monitored for data
and will check the break and mark timing and received data words. If data is
present and is DMX the green led above the input will be lit.
In the event of a main data failure the Smart Switch 8:4 will check all the other
operating universes back ups and will Switch All to back up if all back ups are
operating correctly. If a back up is not operating correctly or is not present the
Smart Switch will switch over only the universe that has failed, e.g. Switch if Able.
The output red LED’s indicate if the outputs are running in main or back up. If lit
the output has been switched to back up. If the main DMX inputs are functioning
correctly the red output LED’s will not be lit.
Manual Override
On the rear of the Smart Switch 8:4 is a female six pole XLR. The allows the
switch over system to be driven manually from a remote position. Both Switch All
and Switch if Able are remoted through this connector. See table below.
To manually Switch All take Pin 3 (Switch All) to Pin 5 ( Common)
To manually Switch if Able take Pin 4 (Switch if Able) to Pin 5 ( Common)
The yellow LED will light if manual Switch All is used.
The yellow LED will light and slow flash if manual Switch if Able is used.
If both are used together the unit will Switch All.

Pin1 Buss R Slave
Pin 2 Buss A Slave
Pin 3 Switch All
Pin 4 Switch if Able
Pin 5 Common
Pin 6 Not used
Slaving units for more inputs
If more than 4 universes are required the Smart Switch 8:4 can be slaved to
additional units via the six pole XLR. If more units are required and/or the manual
remote needs to be used in addition, Y cords can be used to extend the buss to
other units.

Smart Switch 8:4 Manual Mode
In order to allow the unit to operate with protocols other than DMX512 or Hog
Overdrive mode provided that they are RS485/422 compatible. The unit can be
switched to manual only mode by changing the internal PCB mounted switches.
In manual mode the unit will not check the incoming data. The input LED’s will still
show that there is data but only that the input line is ‘waggling’. The unit can only
be controlled from the remote input. Either Switch All or Switch if Able will cause
the outputs to switch to backup. The relevant backup led will light if there is backup
data available, and the manual led will light.
To change to manual only do the following. Disconnect the unit from the mains via
the IEC inlet. Remove the six side case screws. Move the four slide switches – one
per card to the ‘MAN’ setting as indicated on the cards.
Make sure that all four switches are changed. If not the front panel LED’s will not
sequence on start up.
On power up in manual mode all front panel leds will go to full and then off. In
automatic mode the leds will sequence data1,data2, output.
POWER SUPPLY
The mains input to the transformer is via a 2A a/s fuse. A spare fuse is provided in
the input connector block. The Smart Switch 8:4 will operate with mains in @
100VAC to 250VAC
19” RACK MOUNTING
The XTBA Smart Switch 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.
