Martin Professional™ Exterior 50 & 100™ system user manual
System control: general
The Exterior 50 & 100 system can be:
• controlled using a DMX control device or PC application,
• set up and controlled using a PC running the Martin M-PC™ RDM-
compliant Windows application via a Martin USB Duo™ USB/DMX
interface box, or
• set up and programmed to display a single default scene using the
infrared remote control unit available as an accessory from Martin™.
Data link
The DMX (and RDM if used) data signal from a DMX controller or PC must
be sent to the PSU via a data link that conforms to DMX512-A
specifications.
• Use DMX cable for the data link (microphone cable does not have the
correct impedance).
• You must normally create the data link from the control device to the
PSU as one single daisy chain (i.e. you must not split the data link into a
‘Y’), but you
can
split the DMX data link into up to five branches if you
use an amplifier/splitter such as the optically isolated Martin DMX 5.3
Splitter (P/N 90758140) or Martin RDM 5.5 Splitter (P/N 90758150)
installed in a dry location.
• You must connect only one PSU directly to the
DMX OUT
data
throughput in a PSU (but you can connect one daisy chain of PSUs in
which each PSU is connected to the previous PSU’s s
DMX OUT
data
throughput).
• You must connect only one Splitter or one Luminaire directly to one
OUTPUT
hybrid output in a PSU (but you can connect one daisy chain
of Splitters and Luminaires).
• Do not connect more than one Splitter (or one Luminaire) to the three-
way data output quick-lock terminal block marked
GND
,
DMX-
,
DMX+
and two-way 30 VDC output screw terminals marked
+U
and
-U
in a
Splitter.
• Do not connect more than one Luminaire to the four-way hybrid output
quick-lock terminal block marked
DMX-
,
DMX+
,
+U
,
-U
from a Splitter.
Two simple rules are:
• You can split the data link
before
a PSU using an amplifier/splitter
device, as stated above, but do not split the hybrid power and data
cable link
after
the PSU into a ‘Y’.
• Do not connect more than one device or more than one daisy chain to
one output from another device, because this will split the link into a ‘Y’.
