DMX
To control the SkyPanel via DMX you need a DMX data link.
The SkyPanel has 5-pin locking XLR sockets for DMX / RDM
data input and output. The default pin-out of both sockets is:
Pin 1 = Shield
Pin 2 = DMX Data - (cold)
Pin 3 = DMX Data + (hot)
Pin 4 = DMX Data - (cold)
Pin 5 = DMX Data + (hot)
Pins 4 and 5 are not used by the SkyPanel but are bridged
between input and output sockets. These pins can therefore be
used as a pass-through connection for an additional data
signal if required.
Do not overload the data link.You must not connect more than
32 SkyPanels per data link. Depending on the channel require-
ments the address space of one data link (512 channels) may
not be enough to control all products of the installation. You
may set more than one SkyPanel to identical DMX addresses
to obtain identical behavior. For independent control every
SkyPanel needs to be assigned an individual address range.
If you need to control more SkyPanels individual, you need to
set up additional DMX data links.
Tips for a Reliable Data Transmission
• Use shielded twisted-pair cable designed for RS-485 devices
or CAT 6 network cables. Standard microphone cable cannot
transmit control data reliably over long runs. 24 AWG cable is
suitable for runs up to 300 meters (1000 ft.). Heavier gauge
cable and/or an amplifier is recommended for longer runs.
• To split the data link, use a DMX splitter. Use an RDM com-
patible splitter when you use the RDM functionality.
• Install a DMX termination plug on the last product of every
DMX data link. Terminate the DMX data link on both ends,
when you use the RDM functionality. Ask your system
specialist for details.
To Connect the Data Link
• Connect the DMX data output from the controller to the data
input (male XLR) of the first product on the data link.
• Run the data link from the data output (female XLR) to the
data input of the next product.
• Terminate the data link by connecting a 120 Ohm, 0.25 Watt
resistor between the data 1 hot (+) and cold (-) conductors
(and between data 2 hot and cold if used) at the data output
of the last product on the link.
