In response to a perceived industry requirement for lower
cost DMX512 cable installations, the DMX-over- Category 5
Cable Task Group was formed by ESTA's Control Protocols
Working Group (CPWG) at the January 1998 TSP meetings. The
goal of this testing was to establish whether Category 5
cable, or "generic premises cable" as it has become known,
could be used as a low cost substitute in permanently wired
DMX512 installations. Data obtained from test sessions
confirms that, in most respects, UTP and STP Category 5
cable can be expected to perform at least as well as EIA-485
rated data cable for DMX512 applications.

RS-232 to Microplex (MPX) Interface by Infidigm - The
RS-232 to Microplex (MPX) Interface allows the PC to control
Microplex devices. The interface converts a serial data stream
from the PC into the microplex protocol. The interface gets
power through the XLR cable from other MPX devices (Dimmer
Box). The interface can be programmed through the PC to
control between 6 - 96 channels. The interface is also
electrically isolated from the PC serial port.
-
Microplex (MPX) Project by Infidigm - This project will
allow you to build an interface from your PC to Microplex
dimmer boxes. The Microplex (MPX) project is a collection of
the interface and supporting software.

Analogue light controlling desk - very simple and basic
four channel lighting desk with standard 0..10V control
voltage output, works with most of the dimmer racks with
analogue 0-10V input
-
CV-ranger - transforms a 0-5V input voltage to a
adjustable range between 0-10V
-
Dimmer Control Voltage Polarity Changer - Some older
Strand dimmer units used a zero to -10V control signal, and
the standard analogue control voltage is zero to +10V. This
project allows the easy conversion from one standard to
another. This is a very simple project, but may turn out to
be a lifesaver for small theatre groups and the like.

Ethernet in light controlling
-
Art-Net Protocol - Art-Net is a 10BaseT Ethernet protocol
based on the TCP/IP protocol. Its purpose is to allow transfer
of large amounts of DMX512 data over a wide area using
standard networking technology.
-
DMX512 Takes A Backseat As Major Companies Embrace Ethernet
- DMX512 has been remarkably successful in its wide
acceptance, but the basic scheme of DMX512 is not up to the
task of carrying the quantity and variety of data that needs
to move in a modern large intelligent lighting system
-
ESTA's Advanced Control Network (ACN) Protocol Suite - The
Advanced Control Network (ACN) is intended to provide the next
generation standard for the distribution of data in lighting
control networks. Ideally, ACN will unify lighting control
networking, allowing a single network to carry many different
kinds of lighting-related data and to connect equipment from
different manufacturers. ACN is not limited to lighting. It is
expected that support for audio control and stage automation
will also be incorporated. ACN will operate using Ethernet and
is intended partly to address the limitations of DMX512.
