Figure 35 – Matrix 300N PoE PSE Midspan Alternative B Connections NOT SUPPORTED
CAUTION: For Matrix 300N 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 DL.CODE software. For more details refer to the Help On Line
page of the Reading Phase step (Channels) in DL.CODE.
Details regarding the connections and use of the interfaces are given in the next paragraphs.
