DMX Image Output

Displays final image on DMX512 controlled lighting devices, such as LED array and LED matrix.

In the example figure above,

Uses lighting devices with 4 x 4 display dots.
Places 15 devices, 5 in horizontal and 3 in vertical.
There are 20 display dots (pixels) in horizontal and 12 display dots in vertical.
2 DMX interfaces are required.
A DoctorMX is used for one, and ArtNet for another.

Lighting Device Requirements
Currently, lighting device with specific characteristics is required.

Each display dot consists of 3 components (RGB), that are controlled by 3 contiguous DMX channels (in R, G, B order).
Contiguous DMX channels are used for display dots.

Dot Order
Dot order can be matched to device.
If not specified, by default, left to right, top to bottom (in same order with English text).

Default Dot Order

For a horizontal line, display dots from left to right [ 1 2 3 ... ].
Corresponding DMX channel is:
[ (1,2,3) (4,5,6) (7,8,9) … ]
(each display dot (R,G,B))
For a vertical line, display dots from top to bottom.
[ 1 ]
[ 2 ]
[ 3 ]
:
Corresponding DMX channel is:
[ (1,2,3) ]
[ (4,5,6) ]
[ (7,8,9) ]
:
(each display dot (R,G,B))
For 2D matrix, display dots form topmost horizontal line left to right,
then second horizontal line left to right,
:
finally bottommost horizontal line left to right.
(in the example below, 3 display dots in each horizontal line)
　［ 1 2 3 4 ］
　［ 5 6 7 8 ］
　［ 9 10 11 12 ］
　［13 14 15 16 ］
:
Corresponding DMX channel is:
　［ ( 1, 2, 3) ( 4, 5, 6) ( 7, 8, 9) (10,11,12) ］
　［ (13,14,15) (16,17,18) (19,20,21) (22,23,24) ］
　［ (25,26,27) (28,29,30) (31,32,33) (34,35,36) ］
　［ (37,38,39) (40,41,42) (43,44,45) (46,47,48) ］
:
(each display dot (R,G,B))

If [Specify dot order], dot order of device unit can be specified arbitrary.

A dot with order [0] is not used.

Unit Size (dots)
Specify display dots per lighting device (not actual metric).

Layout (units)
Specify number of lighting devices to be used.

Display Size (dots)
Shows total display dots in whole.

Unit Address (Interface / DMX Channel)
Shows DMX interface number and base DMX channel for each lighting device.
Each lighting device must be placed, cabled and configured as this indicates.

Interface
Relates DMX interface number with actual interface hardware device.
For each interface number, an ID of DoctorMX interface box or ArtNet must be assigned.

Currently, DoctorMX interface box is shipped with unique 4 digit ID programmed.
This ID is immutable regardless USB topology.

Early products has no unique ID, instead 8 digit ID is generated according to USB topology.
It is unique unless USB topology is changed.
We provide a service (at cost) to upgrade early products to recent specification.
For details, see this page.

Use DMX Image...
While checked, DMX Image output is used.

Signal Parameter...
Some of DMX signal timing can be adjusted.

Each setting specifies [ minimum ], and actual average is greater.
Except, [ Mark Between Slots ] of [ 0 ] is actually 0uS.
In other case, on average, about 10uS longer than specified.
Some lighting devices work correctly when [ Mark Between Slots ] is increased.
These settings are saved as preference, and reproduced at next startup.

This feature requires DoctorMX interface box with serial number (ID) 1201 and later.
Earlier interface box needs to be upgraded, and we offer this service (at cost).
For details, seethis page.

This feature is not applicable for ArtNet output.
However, if an ArtNet output is received by DoctorMX, and it uses DoctorMX interface box for final output, Signal Parameters can be adjusted there.
