Figure 1: connectors on the controller front panel
The connectors are briefly described below. A detailed description follows in the next sections.

Connectors P1 and P2 are used to connect the four illuminators

Connector P3 is used to supply power

Connector P4 is used for input/output synchronization and for serial RS485 communication

Connector P5 is a USB port (B type), not active at the moment

Connector P6 is an Ethernet RJ45 jack
For connectors P1, P2, P3 and P4 a mating plug is provided in the controller package. For
convenience the relevant manufacturer part numbers are listed in
Table 1: mating plugs for the
controller connectors . Even if equivalent mating plugs may be available, these are the recommended
components.
Connector designator Manufacturer Mating plug part number
P1, P2 Phoenix Contact 1757035
P3 Phoenix Contact 1757022
P4 MH Connectors MHDM25SS

8.2. Power and logic supply
The power supply voltage must be between 24 V and 48 V. A dedicated and well-regulated switching
power supply is required. The external power supply must be capable of supplying the average and
peak currents needed for all active light outputs.
Choose a power supply unit that limits its output current by design or use protecting fuses. The fuses
should be appropriately de-rated if mounted in an enclosure, as the inside temperature can be higher
than the ambient temperature.
Ensure that the wire gauge used for these power connections is appropriate for the current to be
