+5VDC from board if fuse F2 is placed.
3(PORT1 LINK)
LOW if Port 1 is connected to a valid Ethernet device.
4(PORT1 DUPLEX)
LOW if Port 1 is operating in FULL DUPLEX. Predominately HIGH if Port 1 is
operating in HALF DUPLEX. In half duplex mode, the pin will go LOW
temporarily to indicate COLLISIONS on PORT 1.
5(PORT2 LINK)
LOW if Port 2 is connected to a valid Ethernet device.
6(PORT2 DUPLEX)
LOW if Port 2 is operating in FULL DUPLEX. Predominately HIGH if Port 2 is
operating in HALF DUPLEX. In half duplex mode, the pin will go LOW
temporarily to indicate COLLISIONS on PORT 2.
7(PORT3 LINK)
LOW if Port 3 is connected to a valid Ethernet device.
8(PORT3 DUPLEX)
LOW if Port 3 is operating in FULL DUPLEX. Predominately HIGH if Port 3 is
operating in HALF DUPLEX. In half duplex mode, the pin will go LOW
temporarily to indicate COLLISIONS on PORT 3.
9(PORT4 LINK)
LOW if Port 4 is connected to a valid Ethernet device.
10(PORT4
DUPLEX)
LOW if Port 4 is operating in FULL DUPLEX. Predominately HIGH if Port 4 is
operating in HALF DUPLEX. In half duplex mode, the pin will go LOW
