ART-NET ALTERNATE MAPPING
This feature is used in conjunction with the
Art-Net Trap-and-Convert
option, which is set from the Port Configuration
menu. This feature does not affect unicast Art-Net packets.

The Art-Net protocol uses two hexadecimal numbers, a ‘subnet’ and a ‘universe’, to define its DMX universe numbering.
Numbering is usually shown as # - # and the valid range is from 0 - 0 (zero-zero) to F- F.
However, most other common protocols including sACN do not have a universe ‘zero’. The issue is compounded because
some Art-Net implementations are shown in a straight decimal representation (1, 2, 3, 4…) without any indication if “1”
corresponds to Art-Net universe 0-0 or to 0-1.
By default, Art-Net Universe 0-0 is ignored by the VIA and the packets discarded. When Alternate Art-Net Mapping is
enabled, VIA switches will map Art-Net Universe 0-0 to sACN Universe 1. When Alternate Art-Net Mapping is disabled, Art-
Net Universe 0-0 will be ignored by the VIA and Art-Net Universe 0-1 will be routed as sACN Universe 1.
QoS (QUALITY OF SERVICE)
Quality of Service determines the relative priority of different data packets, which in turn determines which packets should
receive preferential routing from a VIA switch. QoS is often used for the distribution of video and audio signals, including the
Dante® audio standard, to meet the signal’s required timing constraints. Please remember that giving all data high priority
is the same as treating all traffic equally.
