Dimmer Outputs
The dimmer outputs connect from the FDX3000 processor to the dimmer module trays. They should
generally be preconfigured from the factory. They are grouped in blocks of 12 dimmers, from A (1–12)
through H (85–96).
Feedback
The feedback connections allow the FDX3000 to determine the status of voltage and current for
modules that support sensing. The two feedback connections should be made from the factory.
15 VDC
The 15 VDC connection provides 15 V power to the FDX dimmer modules.
Option Connector
The option connector allows field connection of the rack options such as panic (see
), stations
), and a remote beacon. For information on these connections, see the termination
markings on the rear of the FDX3000 carrier.
DMX Connections
The FDX3000 processor features DMX In and Thru connections on two industry-standard 5-pin
XLR connectors. The two DMX ports, A and B, are fed to both of the redundant processors.
Ethernet Connections
Two Ethernet connections are provided using Neutrik
®
etherCON
®
connectors, which may be either
connected to a Neutrik etherCON jack or a standard RJ45 connector. Net A connects to the A (upper)
CEM3, and Net B connects to the lower. The CEM3s feature an internal switch allowing use of the rear
and front panel Ethernet connections at the same time.
Power Input
The power input connector is a three phase supply, fed from the supply in the rack. The FDX3000
processor will function regardless of any phase loss; as long as at least one phase is still active the
processor will still dim any dimmers which still have power.
