DMX-512 Input A DMX-512 Input brings in the value of a DMX channel. DMX-512 is a
protocol used by most lighting consoles, dimmers, moving lights and other
similar devices.
WATCHOUT uses the computer network to receive DMX data using the Artnet
protocol (see http://www.artisticlicence.com/). Many modern lighting
consoles can send Artnet over an Ethernet network. In other cases, a DMX-to-
Ethernet adapter must be used. In either case, you need to know the DMX
channel number(s) to be used for WATCHOUT, as well as the Artnet Universe
number used to send those channels.
You must configure WATCHOUT to receive that specific Artnet Universe
number. This is done under the Control tab in the Preferences dialog box (see
“DMX-512 Universe” on page 123).
Add a “DMX-512 Input” to the Input window. When done, click OK in the
DMX Channel dialog box, and verify proper operation of the input by moving
the fader for the specified channel and observing the bar graph in the Input
window. WATCHOUT normalizes DMX values to a number in the range 0
through 1, as indicated in the Input window’s Value column.
Resolution. Some lighting consoles support high resolution (16 bit) values.
Such high resolution values are generally required to control, for example, the
position of images in WATCHOUT, since the standard 8 bit DMX resolution
(0...255) is too low for this purpose.
If your console is capable of outputting 16 bit DMX values, choose “High (16
bits)” for the Resolution setting, and enter the base (coarse) channel number.
WATCHOUT will derive the coarse 8 bits from this channel and the fine 8 bits
from the following channel.
