The MDC-200 communication cable is used with PoE (power over ethernet) spectrometers. Using this cable, the spectrometer can directly be connected to a computer or router which support PoE. When no PoE functionality is available, power needs to be required elsewhere. For this a PoE injector can be used, such as the Medusa PoE injector unit.

Connection scheme

Both connectors share the same pin-out. That is, pin 1 of the Lumberg connector is connected to pin 1 of the RJ45 connector, etcetera. Note that pin 4 and pin 5 have the same function, but they are not connected. The same applies for pin 7 and 8.

Pin numbering

The RJ-45 connector follows the T-568B standard.
