Auto Terminate Feature
The VistaBeam 610 and 310 series have an “ AUTO TERMINATE”
feature. The last fixture that does not have an XLR cable attached
to the DMX “Out” port will automatically terminate.
Any theatrical lighting board with DMX512 protocol can be used to
individually turn on/off lamps in a fixture. VistaBeams can be
jumpered using the IN and OUT ports. As many as 100 fixtures can
be jumpered on one chain as long as the DMX cable run remains
under 1000 feet or 40 x 25ft DMX cables.
Note: When operating fixtures at great distances from the dimmer board, it is recommended
to use Opto-Isolators to provide DMX signal amplification.
Do Not use Microphone Cables and other general purpose, two-core cables designed
for audio or signaling use. They are not suitable for DMX512. Problems due to incorrect
cabling may not be immediately apparent. Microphone cables may appear to work fine,
but systems built with such cables may fail or be prone to random errors. Cable must comply
with EIA-485 (RS485).
Note: If a fixture loses its DMX signal, it will hold its last DMX command. For this reason,
it is important to turn a fixture off using the DMX commands. For example, if you try to turn off
the lights by turning off the dimmer board, the fixtures will remember their last DMX command
and stay on. The fixtures require a DMX “Off” or “Black-out” command in order to turn off.
DMX Cables
Cable must comply with EIA-485 (RS485).
The fixture uses five-pin XLR male and female connectors to receive
DMX signals from the Dimmer Board and jumper the fixtures in a
series. DMX pin-out wiring follows the USITT DMX512 standard:
Pin 1: Shield
Pin 2: Data –
Pin 3: Data +
Pin 4: Spare –
Pin 5: Spare +
Note: Pin four and five in the Fixture are connected internally as
Pin four to four and Pin five to five. Connecting Pin four and five as
the pass-thru allows secondary data to be passed through
other equipment.
