2.2 Cabling system
The Inspire External Control Box has 3 control data outputs (Port 1, 2, 3). Each control data output
provides remote control for 32+ daisy-chained Inspire Terminal Strip fixtures. The maximum length
of the DMX cable from each data output of the External Control Box to the first Terminal Strip fixture
must not exceed 500 ft (152 m).
Each Inspire Terminal Strip fixture has its own signal buffer with a bypass relay. This means the
signal transmitted from the UL924 Control box is being regenerated at each fixture. Therefore, the
number of fixtures on a single link can exceed the typical 32 limits, in theories up to 128 fixtures
could be daisy-chained. For ease of troubleshooting and to minimized the single point failure factor,
it is suggested to divide the fixture count per link over the three outputs of the UL 924 Control box.
In case of power failure on a fixture, an internal relay will let the data pass through.
It is also important to know that the signal coming out of the UL924 Control Box cannot be split
using Y cables or DMX opto-splitter. However, Opto-Splitters or DMX buffer can be used to isolate
links between fixture and control box.
Because the signal is being regenerated at each fixture, the first fixture on the link must have a 120
Ω resistor (terminator) between the + and – on the input side of the fixture.
If the cable length between the subsequent fixtures on the link is less than 100 feet (30 meters) no
additional terminator is needed. If longer, a 120 Ω resistor can be added at the fixture data input
where the longer cable connects.
