Outstation Cables
We have come very close to meeting the design objective with
only few limitations on cable type when lengths exceed 500m.
The Outstations may be wired using either daisy chain, star
and/or loop wiring topologies. Any combination is permitted.
Even with a cable break in the loop configuration, the system
remains 100% operational.
Permitted Outstation wiring topologies
Design objective:
Wire up the venue in any manner using almost any type of
three core cable, and then plug anything in anywhere.
It is suggested that the Cue Light system be restricted to a
maximum of about 40 Outstations and a total of 2,000m
of cable. These numbers can often be exceeded.
See What’s the Limit on page 31.
(6500 ft)
All Outstations are
powered from the Master Station by the Phantom Power
principle where power is sent down the data pair (XLR pins
2&3) and returned through the ground/screen
conductor(XLR pin1). Outstations can be connected or
disconnected while the power is on.
Star Quad and multicore (snake) cables may be used.
Digital snakes cannot be used as they do not pass power or
allow bi-directional signals to be sent down the cable.
Even though the system is very resistant to interference, it is
good engineering practice to install the Cue Light wiring
away from mains wiring. It will also work with cables wired
with XLR pins 2 & 3 swapped.
It is permitted to have dozens or even hundreds of sockets
spread around a venue. The Master Station can be plugged
into any one of these sockets. Outstations are then
connected to the nearest convenient socket.
Outstations can be wired up in any physical sequence.
Outstation #2 does not have to follow #1.
The Outstations are connected by a one pair screened
cable fitted with 3 pin XLR connectors.
