Kino Flo Image 80, 40 & 20 DMX - Manual (Page 8)

The DMX Terminate Switch must be set to open ( O ) on
Fixtures within the DMX chain.
Set to closed ( I ) when the Fixture is the last DMX control
device in the chain.
Note: When the last Fixture's DMX Term is set to “I,” it will
absorb all energy in the DMX line, ensuring DMX signals
are transmitted correctly. If a signal is not terminated, it is
called a “Reflected Wave,” and may create
transmission
errors by causing valid DMX signals to be canceled.
Any theatrical lighting board with DMX 512 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 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 for other equipment.
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 or Ballast loses its DMX signal it will hold it’s last DMX
command. For this reason it is important to turn a Fixture or Ballast 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 or Ballasts require a DMX “Off” or “ Black-out” command in order to turn
off.
