Martin PDE Junction Box / Break-In / Break-Out Cable user guide

Data connection to Passive Junction Box or Break-In Cable using P3
The Martin P3 System Controller combines control information from the lighting console with a
video feed from a media server. This is distributed to the fixtures using the P3 protocol. Each
Junction Box or Break-In Cable must have its own Ethernet connection from the network switch.
x
Please ensure that network switch can operate at 100Mbit Ethernet link speed towards
the Passive Junction Box / Break-In Cable, as the PDE Hybrid fixtures can only operate
at that link speed.
x
Please ensure that network switch can operate at 1Gbit Ethernet link speed towards the
P3 System Controller, as it can only operate at that link speed.
x
The combined length of Ethernet cable (between network switch and junction box) and
hybrid PDE cable to first fixture must not exceed 90 m.
x
The length of hybrid PDE cable between any two daisy-chained fixture may also not
exceed 90 m.
x
A shielded Ethernet cable must be used between the between the Network Switch and
the Passive Junction Box / Break-In Cable. Use shielded twisted-pair Ethernet cable of
type S/UTP, SF/UTP, S/STP or SF/STP only. The cable must be rated Cat 5e or better.
The cable shield must be electrically connected to connector housings, and the other
devices on the data link must also support shielded connections.
x
Other P3-compatible products such as the MAC Aura PXL and P3 PowerPort 1500 can
be connected to the same network switch to operate all together from the same P3
System Controller.
(The example above shows the Passive Junction Box, but the functionality and connectivity of the
Break-In Cable is identical. Also VDO Atomic Bold and VDO Atomic Dot fixtures are shown, but
any mix of Martin products with PDE interface can be used)

Caution:
To avoid ground loops and damage of equipment, make sure the Ethernet is
galvanically isolated when linked between equipment of different potentials or power
sources.
