DMX TECHNOLOGY
DMX-512
DMX (Digital Multiplex) is the name for a universal communication protocol for communication
between corresponding devices and controllers. A DMX controller
sends DMX data to the attached DMX device(s). The DMX data
transmission is always a serial data stream which is sent from one
connected device to the next via the DMX IN and DMX OUT sockets
on any DMX-enabled device (XLR connectors), whereby the maxi-
mum number of devices may not exceed 32. The last device in the
chain must be equipped with a terminator.
DMX CONNECTION:
DMX is the common "language", through which a wide variety of equipment types and models
from different manufacturers can be connected and controlled via a central controller, as long
as all the devices and the controller are DMX-compatible. For optimum data transmission, it is
necessary to keep the connection cables between the individual devices as short as possible.
The order in which the devices are integrated into the DMX network, has no influence on the
addressing. In this way, the device with the DMX address 1 can be placed at any position in
the (serial) DMX chain, at the beginning, end, or anywhere in the middle. If a device has been
assigned the DMX address 1, the controller "knows" that it must send all the data associated with
the address 1 to this device, regardless of its position in the DMX network.
