JP5, the Port Address jumper:

The WDP Reader in Bus Interface mode can use any of four different port addresses: hex 220, 240, 2C0 and 2E0. The default setting is 220, which most people will be able to use with no problem.

Occasionally a tape controller, bus mouse, network board, real-time clock or other add-on may be using address 220 (compare add-on board switch settings with the manuals) and you'll need to choose another.

JP7, the Interface Method jumper:

JP7 is the jumper used to select wedge or bus installation. Use the Wedge Interface setting if you are installing the WDP Reader in external or internal wedge mode. Use the Bus Interface setting if you're installing it as an internal bus reader.
