Patching is an App that patches and controls DMX512 data. (Downloads The Classic Image is educational.)
Quick start shows the way to running patch.
Field example shows you an example use of the PIOS system.

Please note that special control gimmicks (clock, power meter, audio analyzer, matrix TV) are listed as products. They all use PIOS I/O as their base for controlling the fixtures.

Translated to an old german abbreviation PIOS means :

(P)ersonen - persons
(I)nformationen - informations
(O)bjekte - objects in the meaning of houses and other places
(S)achen - things

Well, you'll agree, thats exactly what you have in any show and on stage.

PIOS DMX512 Software for Mac OS X
An app with a graphical user interface. PIOS fully supports all 256 Universes DMX512 in and out simultaneously ArtNet can carry. Real DMX In/Out is done using USBDMX as ArtNet Node on the Mac or ArtNet nodes on Ethernet.

USBDMX by Lighting Solutions (used by PIOS)
There are the drivers and the application for Mac OS9. This can be used as a DMX monitor. There is an obsolete application for Mac OS X which bridges to ArtNet in Terminal. The USBDMX becomes an ArtNet Node with this.
This chapter gives in deep information about the use of an USBDMX device on the Mac, it is intended to be read by coders. Users should go to the PIOS chapter. Ongoing, since Mac OS X, this chapter is obsolete because in Mac OS X there is no driver required; The PIOS app contains the driver.

ArtNet by Artistic Licence (implemented in PIOS)
ArtNet is supported under Mac OS X within the USBDMX section and by PIOS. The Mac emulates a DMX Hub and bridges attached USBDMXes to ArtNet.
The PIOS app also works as a ArtNet monitor if you want to see what goes on on your Ethernet. The tutorial gives you an overview about what ArtNet Protocol is.


By natural none of the present operating systems can deal with this lighting hardware cause it is propieterian.
This means you need drivers for your device, just that the operating system can use your devices. The drivers and their discription for users and coders are found in the chapter named like the device. If your device is not present and you'd like to have it supported or bridged (to e.g. ArtNet) send me a sample device and I'll write it.
This is my contribution to the Mac community. If you're a coder and do some software that deals with stages at all feel free to ask me for detailled API information.
