DMX512
DMX is an ANSI standard control protocol originally birthed from the entertainment
industry. Now DMX is used still in the entertainment industry but also in many
architectural applications. Your Z-Max cabinet, if so equipped, has the ability to
receive DMX and allows each relay to be assigned to one of the 512 DMX channel
addresses.
The settings for DMX are described in this chapter.
Operational Mode
DMX has several operational modes which define how DMX controls the relay cabinet.
The available operational modes are as follows:
• Disabled - The cabinet can be programmed to not
listen to DMX commands. This is
useful when you do not have any DMX devices hooked up to the system.
• PRI ON - REL OFF - DMX operates in last action mode for dmx channels at the
same priority level as DMX when levels are greater than 0, and relinquishes control
to other channels when the value=0. (last action)
• PRI OFF-REL ON - Relinquishes control to other priority levels when the DMX
channel level is greater than 0, and operates in last action mode at the priority level
of DMX to turn the relays off when the DMX channel level=0.
• Forced - Means that DMX will always have control over other control sources of the
same priority.
DMX Start Address
When DMX is used to control relays in the cabinet, each relay requires the assignment
of a DMX channel, or none, whichever is appropriate. This setting quickly sets and
sequentially renumbers all relays in the cabinet, starting at the given start channel.
Valid values for DMX channels are 1-512.
