MDC-200 cable

| Communication protocol | Ethernet (PoE) |
|---|---|
| Last spectrometer | 2016-T037.007 |
| Voltage protection | None |
| Connector A | RJ-45 |
| Connector B | Lumberg, 0332-08 |
| Dust caps | Lumberg 0383, Lumberg 038399 (no chain) or Lumberg 038899 (plastic) |
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.
