DMX
To control the Orbiter via DMX you need a wired or wireless DMX data link.
The Orbiter 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 Orbiter 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 Orbiters per data link. Depending on the
channel requirements 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 Orbiter to identical DMX addresses to obtain iden-
tical behavior. For independent control every Orbiter needs to be assigned an individual address range.
If you need to control more Orbiters 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 / CAT 7 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 compatible 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 fixture on the
data link.
• Run the data link from the data output (female XLR) to the data input of the next fixture.
• 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 fixture on the link
or activate the internal termination of the Orbiter.
SYNC Interface
The SMA Interface „SYNC“ has no function and cannot be used by the user.
