3. Using the APC Hub
The Leprecon APC Hub provides several important functions in an APC panel
system.
1. DC power - the Hub will power up to ten APC panels using RJ45 terminated CAT5
cable.
2. DMX Interconnect - A five pin DMX input connector is wired internally to the APC
CAT5 cable.
3. Optical Isolation - The Hub includes a DMX isolator and buffer to provide the best
signal integrity from the panels to the lighting system.
Two additional features of the Hub are designed to make it more tolerant of fixtures
that do not fully comply with the DMX512 specification:
1. DMX Deceleration - data rates and time between packets are relaxed for fixtures
that cannot cope with full speed DMX transmission.
2. Start Code Stripper - Some poorly designed fixtures or dimmers may respond to
the internal panel communication used in an APC system. Filtering in the Hub
prevents these signals from reaching the fixtures.
The Hub has two optional mounting accessories, a pair of wall mount brackets and a
pair of rack mount brackets. If your application requires either of these accessories,
they are available from your Leprecon dealer.
