DMX-512 Master
The gateway supports the DMX-512 master driver on its RS-485 port, and
provides for control of all 512 channels. The DMX-512 master protocol allows
anything connected to the gateway (such as a PLC or a building automation
system) to be used as a universal DMX controller device.
11.6.1.1
Overview
Some notes of interest are:
•
Control any DMX-enabled device including lighting fixtures, dimmers, special
effects, and fog machines.
•
Configurable, variable channel output.
•
Simple configuration consisting of channel-to-database address
assignments.
For instructions on how to configure the gateway to use the DMX-512 master
protocol, refer to section 8.8.6.
11.6.1.2
Connections
While there are a variety of different DMX-512 connector types in existence, most
standard DMX-512 connectors use either XLR 5-pin or 3-pin connectors (refer to
Figure 57 and Figure 58). A female connector is fitted to a transmitter device
(e.g. a console), while a male connector is fitted to a receiver device (e.g. a
dimmer or servo).
An appropriate wiring harness must be used when connecting the DMX-512
network to the gateway’s RS-485 port. This can be accomplished by using off-
the-shelf DMX-512 cabling with bare-wire terminations on one end, or by simply
cutting a standard DMX-512 cable in half and stripping back the wires. Refer to
Table 5 for an overview of DMX-512 pin assignments and connections.
