DMX-512 Master
To configure the gateway for DMX-512 Master, click on the
RS-485
Configuration
tab and select
DMX-512 Master
in the protocol dropdown menu.
The DMX-512 Master configuration consists of assigning database bytes to
channel numbers. Each byte in the database corresponds to one channel in the
DMX packet. The channel numbers start at 1 and may range up to 512.
8.8.6.1
Protocol Selection Group
Scan Rate
This is the time the device will wait between sending packets. This may be useful
if slave devices require additional time between sent packets. If no additional
delay time is needed, set this field to 0. For more information, refer to section
8.4.
8.8.6.2
DMX Data Configuration
Database Start Address
This field is the location in the database where the channels will be mapped
starting with channel 1.
Num Channels
This field is the number of consecutive channels to map into the database. Enter
a number between 1 and 512.
8.8.6.3
Configuration Example
This example will configure the gateway for end-to-end communication using
DMX-512 Master and Ethernet/IP Server.
Say, for instance, a museum has a display that is illuminated by two DMX-
enabled lights. It is desired that the display lighting is changed into different
scenes throughout the day by the museum’s building automation system (BAS)
that is networked using Ethernet/IP. The lights each have four channels, one for
each red, green, and blue color, and another for the dimmer.
Configure the Ethernet port using the above requirements
•
Connect the gateway to the PC via a USB mini type-B cable.
•
Open the configuration utility and select the ETH-1000 (see section 8.1 for
more information on selecting a device).
•
Click on the
Ethernet Configuration
subtab.
•
Click
Use a static IP address
and enter an IP address for the gateway to
reside at on the BAS network.
•
Check the checkbox next to
EtherNet/IP
Server
in the
Protocol
dropdown
menu, and then click on the
EtherNet/IP Server
subtab.
•
Enter “0” into the
Produced Data Start Address
and
Consumed Data Start
Address
fields.
