Generic Ethernet adapter
Eurotech has developed a fail-safe circuitry that can be installed to prevent faulty and damages. To prevent wrong connections between the CPU-1220 and the Ethernet adapter Eurotech has developed a generic adapter that can be used together with the CPU-1220 for installing both the Realtek chips.
The following drawing describes the solution for a generic Ethernet adapter tolerant regarding the supply voltage present on pin 1 of J4 CPU-1220 Ethernet connector and based on the version of the Realtek RTL8139 chipset installed, and that may be integrated into a carrier board.
