6. Electrical hookup
For APC only systems (no DMX controller), CAT5 cable with Ethernet type RJ45
connectors is used to interconnect panels and the dimmers or DMX fixtures together
in a single daisy chain configuration. Each APC panel has two RJ45 jacks, making
daisy chain connection simple to implement.
The APC cable is carrying DMX-512, so standard practice for DMX signals must be
observed.
1. All wiring must be daisy chain connection ONLY. No Tee, star or multipoint
connections are allowed.
2. Each end of the DMX chain must be terminated. Jumpers on the APC panels
allow the last panel in the line to be terminated.
3. DMX512 cannot connect to more than 32 devices without external buffer
amplifiers.
The diagram below illustrates a typical system that includes a DMX controller. All
panels and DMX devices must be connected in a daisy chain manner as shown.
