resemblance to the old load patch panels that have been obsolete for almost
twenty years.
DMXQConnect is a software tool enabling the user to construct a virtual
DMX data communications network on a personal computer. It will permit the
user to add descriptive text notes and device address information, and then
transmit the resulting interconnectivity data to an electronic matrix patch system,
or crosspoint router, that physically interconnects all of the control system's
elements in an organized, logical manner. High-speed solid-state crosspoint
matrix devices that are commonly used in digital telephone switching systems
carry out the patching function.
Unlike most common local area networks, a DMX512 network often
requires many separate data paths to handle the number of device addresses
and codes necessary for medium to large-scale installations. Each data path
can accommodate only 512 eight-bit codes. As well, it is common practice to
use more than one control console in larger productions, or to provide more than
one location within a facility to "plug in" control consoles. Yet another
complication arises when equipment using communications protocols other
than DMX512, must be connected to the installed DMX wiring system. These
and other factors drove the development of the Gray Interfaces DMXPathfinder
and DMXQConnect as a comprehensive solution to the network problems
faced by all DMX system designers and users.
We designed DMXQConnect to be a simple to learn and use utility. Its
main function is to facilitate the creation of "patch" files on a personal computer,
then to allow the user to send these files to the DMXPathfinder electronics rack
where they are implemented as actual patch configurations. Of course,
QConnect also supports file editing, disk archiving and hardcopy printing
functions. Additional features include the ability to add text notes to each
connection record, and a useful device address calculator that displays (and
prints) the DMX port number and absolute DMX device address for receiving
equipment being operated by control system numbers greater than 512.
