Chapter 11 Inputs and Outputs 201

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.

Enttec and Kissbox.
