1 x Instruction manualDescription
The DMX512-A 1.5 HUB is a full bidirectional isolated DMX splitter orbooster with 1 dedicated input connector, 1 through and 5 output
connectors. All in- and outputs conform to the DMX512-A standard. Thisallows half-duplex data transport, such as RDM, on a normal single pair
DMX connection. The hub is also compatible with DMX512 and DMX512(1990).
All outputs can receive data as well and retransmit it. In this way RDM
data (and other bidirectional data) will be send on all outputs and input.

Connectivity
Right side• Mains
The device operates with an AC voltage between 90V and 260V within afrequency range of 47Hz and 63Hz.
A fixed power lead with lose cable end is directly connected to the device(no plug/connector). Please use an authorized plug and connect the coresin the mains lead in accordance with the following scheme:
Green / Yellow: Earth
Blue: NeutralBrown: Live!!! This equipment must be earthed !!!

The input is separately optical and galvanic isolated from the outputs. TheThrough connector is hard wired to the input connector.
A small switch at the input is provided to disable the bidirectional
functionality for the complete unit. This allows you to use the device as areal leagacy DMX512 (1990) device.
A green LED indicates if the device is powered and a blue LED is used toindicate the data activity on the DMX line.

All outputs are compliant with the DMX512-A specification and are
terminated and rebiased. The outputs are separately optical and galvanic
isolated from the input and from each other.

Features
Isolation• Individual outlet protection
All 5 outputs feature individual isolation and protection. This means that ifa fault occurs on a piece of equipment connected to one output, fixtureson the other outputs are totally protected. In addition the input connector
has its own protection, this gives a double barrier between fixtures andthe console and protects the console against a fault on the mains supply
to the buffer itself (i.e. if the buffer unit was inadvertently connectedacross two phases).
• 1000 Volts optical isolation barrier
Each outlet has an optical isolator that is capable of withstanding voltagesof up to 1000V. Each isolator has its own power supply eliminating any
direct electrical connection between outputs.
Self-healing technology makes sure that the outlets can resist up to 530V
over its data pairs. This means that after such a fault the outlet works fine
again with normal DMX signals.
• Short circuit protection
Each outlet is protected against short circuits, or incorrectly wiredconnectors.
• Modular isolation
All the components that provide the opto-isolation are built into a single
plug-in module for each channel making servicing ultra-simple. In addition
each module is completely interchangeable with other channels including
the input module.
• Line voltage protection
Not only does the Hub protect your various pieces of equipment frominadvertent DMX-to-mains connection it also protects itself. Eachindividual output is protected so that no damage will occur to the buffer
even if they are connected directly to 230V by mistake.

Bidirectional and RDM
Bidirectional means that the splitter can work in Half-duplex over data pin
2 and 3.
All outlets are able to receive data. When an outlet receives data, thenthis data will be retransmitted on all remaining outlets. So all output andinput connectors will get all data send on that line.
This allows bidirectional manufacturer dependent data to be transmitted
between fixtures and controllers. The Hub is protocol independent andsupports in this way communication from different manufacturers such as
High End Systems, Martin Professional, Coemar,...
RDM or Remote Device Management is also supported this way. Thechange over time in data direction is conform to the RDM and DMX512-A
specification. The Hub is a non proxy RDM device with no built in RDM
management controlling logic. This allows us to assure a maximum data
delay between incoming data and outgoing data of 1 micro second.
