Connection and software configuration
The linked document shows direct RS232 connection to a computer and three Ethernet placements: between the sending card or independent controller and the first receiving card, between two receiving cards, or at the end of the chain.
Its NovaLCT-Mars instructions use the Function Card button to open Function Card Management. From there, a card can be added through its serial or Ethernet connection, renamed and associated with the correct serial port. The PDF contains the original connection diagrams and configuration screenshots.
MFN300 card versus MFN300-B box
The MFN300-B is a separate enclosed product. The MFN300 Rev2.1.0 document specifies a DC 3.3–5.5 V input and four light-sensor connections; the MFN300-B V2.0.4 document specifies AC 100–240 V input and two sensor ports. Do not transfer wiring or electrical ratings between these models simply because their names are similar.
