J10 connects Port1 on J4 to either the Advance Data Hiway (ADH) or
Advance DataNET Channel A interface.
J11 connects Port2 on J4 to either the Advance Data Hiway (ADH) or
Advance DataNET Channel B interface. J10 & J11 are configured for
Advance Data Hiway (ADH) on the ANG_EN board.
J2 is used to select the 10Base2-termination resistor. If the 10Base2 port
is not used the jumper is placed between pins 3 & 4. If the 10Base2 port
is connected as an end point device (ANG-DN) then the jumper is placed
between pins 1 & 2.
