32-8 What Are Virtual Connectors?
connectors is 1 to 1. If you attach an output cable to connector 1, you find that the DMX
information output of connector 1 and slot 1 are identical. The output from slots can be
further organized into Virtual Connectors in the Ethernet domain which allows transmitting
data to more than 1 receiver, whereas the output from physical connectors could be
transmitted to only 1 receiver such as dimmer racks, daisy chained moving lights, or splitter
boxes.
The data generated by the lighting console and distributed over the Ethernet is received and
retransmitted by a peripheral device that routes DMX and Ethernet. This device can be
another lighting console, an E-Mix box, or CompuLINK. The E-Mix, for instance, receives
data from the Virtual Connectors on the network and routes the data to the end equipment
in DMX protocol.
In principle, the VCs can transmit protocols other than DMX512, such as CMX bi-
directional, MIDI, High End protocol, and SMPTE.
The numbering of Virtual Connectors is not dependent on the number of existing physical
connectors, so unique information can be sent to many peripherals. The Virtual Connector
space is global to the network.
For further information about Ethernet, consult the documentation supplied with the
Ethernet peripherals: VideoLINK, CompuLINK, and E-Mix.
