PTIONS

The EDK has a number of configuration settings set by four jumpers CJ4 (A, B, C, D) and zero-ohm links. Common EDK
functions can be set using the jumpers as described in sections 5.2. The additional zero-ohm links provide additional

features that may be required to interface with other systems.

All the Jumper link settings are three pin options. There are four sets of options on each header.

The headers are numbered from 1 to 12 with pin 1 marked on the PCB by an arrow pointing to the pin. The diagram below
shows the numbering of these jumper links and indicates jumpers fitted 1-2 for each three-pin jumper.
