Martin PDE Junction Box / Break-In / Break-Out Cable user guide
Pins 4 and 5 in the XLR connectors are not used.
Data connection to Active Junction Box using Art-Net or sACN
Art-Net or sACN data is connected to the system using either of the two etherCON sockets on
the Active Junction Box. The other etherCON socket can then be used to daisy-chain the signal
to another Active Junction Box or other equipment compatible with Art-Net or sACN.
x
The two etherCON ports on the Active Junction Box can operate at 100Mbit/s or 1Gbit/s
link speed, so they will adjust to the highest speed supported by the console or network
switch.
x
The Active Junction Box features a fail-safe bypass mechanism between the two
etherCON ports. So even if the Active Junction Box loses power, it will relay data
between the two etherCON ports.
x
The length of Ethernet cable between the console (or network switch) and the Active
Junction Box must not exceed 90 m.
x
The length of Ethernet cable between an Active Junction Box and the next daisy-
chained Active Junction Box must not exceed 90 m.
x
A shielded Ethernet cable must be used between the console (or network switch) and
the Active Junction Box. 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
The Hybrid PDE output port on the Active Junction Box will always operate at 100Mbit/s
link speed towards the fixtures.
x
The total length of Hybrid PDE cables between the Active Junction Box and the first
fixture must not exceed 90 m.
x
The length of hybrid PDE cable between any two daisy-chained fixtures may also not
exceed 90 m.
x
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.
(this example shows the VDO
Atomic Bold and VDO Atomic
Dot fixtures, but any mix of
Martin products with PDE
interface can be used)
