phyCORE-LPC2292/94 Starting with PCB revision 1179.6 the phyCORE Carrier Board HD200 features 4 solder jumper (J1-J4) that allow signal routing for GPIO37-GPIO40 to different connectors; the Ethernet interface X7 or the Expansion Bus X2. The standard configuration of the phyCORE-LPC2292/94 provides Ethernet signals on these pins. As a result the default configuration of Jumpers J1-J4 will route the signals to Ethernet interface connector X7. Changing this jumper default configuration allows use of the signals on the Expansion Bus in combination with a phyCORE module lacking the Ethernet controller.
