Dual DRd12 Racks with Cross-Bussed ACP
Appendix A
Dual DRd12 with Cross-Bussed ACP
AX12X enclosures provide the ability to interconnect two DRd12 enclosures, allowing full control of
both enclosures from a single Architectural Control Processor (ACP).
Data Interconnect Cable
AX12X enclosures ship with a data interconnect cable, ETC part 7183B7003. The ends of the
interconnect cable install to the Right I/O board in each DRd enclosure.
The ends of the interconnect cable are labeled "Rack 1" and "Rack 2" to indicate where each end of
the cable should be installed. "Rack 1" is the enclosure with the ACP. "Rack 2" is the enclosure
without the ACP.
CAUTION:
If the power feeds to the DRd12 enclosures are not identical in power and
phase, dimming performance may be poor and unreliable.
