CBX ELECTRICAL CONNECTIONS

Figure 35 – Matrix 300™ PoE PSE Midspan Alternative B Connections NOT SUPPORTED

CAUTION: For Matrix 300™ PoE models, the internal Digital Output

circuitry is not powered and supply power is not available to any Input/Output

devices (Vdc=0). Only input device signals can be accepted directly on the

M12 17-pin connector without power.

For these models, if it is necessary to use Input/Output devices, we recommend

connecting them through the CBX, which must be powered separately.

See par. 4.7 for further details.

4.2 MAIN SERIAL INTERFACE

CAUTION: Do not connect to the Main Interface spring clamp terminals if

using Host Interface Modules (Fieldbus) with the CBX500.

The signals relative to the following serial interface types are available on the CBX spring

clamp terminal blocks.

The main serial interface type and its parameters (baud rate, data bits, etc.) can be

defined by the user via VisiSet™ software. For more details refer to the

"Communication" folder in the VisiSet™ Help On Line.

Details regarding the connections and use of the interfaces are given in the next paragraphs.
