Hybrid power + data output
Warning! Before you connect devices to the DMX PowerPort 375’s power + data outputs, visit the
Martin website at www.martin.com and consult the latest PowerPort Capacity document that
explains how many video and/or lighting fixtures of the various types available from Martin can be
driven by one DMX PowerPort 375. Read the devices’ user manuals carefully and respect the system
layout guidelines and limits given in the manuals. User manuals are supplied with products and
available for download from www.martin.com.
Important! Martin VC-Grid, VC-Strip and VC-Dot products are not hot-plugging compatible. Before
you connect these products to or disconnect them from the DMX PowerPort 375, shut down power
to the DMX PowerPort 375 first. This does not apply to VDO Sceptron, VDO Fatron, VDO Dotron,
Exterior PixLine and Exterior Dot-HP; as these products are hot-plugging compatible.
Attention ! Avant de connecter des appareils aux sorties hybrides du DMX PowerPort 375,
connectez-vous au site web de Martin www.martin.com et consultez la dernière version du
document PowerPort Capacity qui détaille combien d'appareils d'éclairage ou vidéo peuvent être
raccordés à un PowerPort 375. Lisez attentivement le manuel d'utilisation de chaque appareil et
respectez les consignes de mise en œuvre et les limites données par les manuels. Les manuels
sont fournis avec les produits et sont disponibles en téléchargement sur www.martin.com
Important ! Les VC-Dot, VC-Grid et VC-Strip ne peuvent pas être câblés à chaud. Avant de les
raccorder au DMX PowerPort 375 ou de les déconnecter, éteignez avant tout le DMX PowerPort 375.
Cette restriction ne s'applique pas aux VDO Sceptron, VDO Fatron, VDO Dotron, Exterior Pixline et
Exterior Dot-HP qui peuvent être connectés à chaud.
The DMX PowerPort 375 supplies DC power at 48 V to Martin Creative Video products over hybrid power +
data cables connected to the power + data output on the rear panel. The output can supply a safe maximum
current of 5 amps when the DMX PowerPort 375 is connected to AC mains power at 100-120 V and 7.5
amps when the DMX PowerPort 375 is connected to AC mains power at 173-240 V.
The output has overload protection. If the output is overloaded or short-circuited, the DMX PowerPort 375 is
immediately shut down. The unit is re-enabled as soon as the overload or short circuit is removed and the
unit has had time to cool down.
Connecting hybrid power + data output
Use only Hybrid power + data cables supplied by Martin to connect Martin fixtures to the DMX PowerPort
375. See ”Accessories” on page 18 for available cables. Do not exceed the maximum lengths for cable runs
specified in user manuals.
To connect the DMX PowerPort 375 to devices:
1. If connecting to VC-Grid, VC-Strip or VC-Dot products, check that the DMX PowerPort 375 is isolated
from AC mains power.
2. Connect Martin hybrid cables with 4-pin male locking XLR connectors to the DMX PowerPort 375’s
power + data output socket on the rear panel (see Figure 1 on page 8).
