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
