Auto Terminate
Each Image 87 & 47 DMX fixture has 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.
Image fixtures 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.
DMX Cables
The Image fixtures use 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: Date +
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 for other equipment.
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 lights will remember
their last DMX command and stay on. The fixtures require a DMX “Off” or “Black-out”
command in order to turn off.
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. Cables must comply with EIA-485 (RS485).
