2.4 Jumper Setting
A pair of needle-nose pliers may be helpful when working with jumpers. If you have
any doubts about the best hardware configuration for your application, contact your
local distributor or sales representativ e before you make any changes. Generally, you
simply need a standard cable to make most connections.
The jumper setting diagram is as below. If a jumper shorts pin 1 and pin 2, the setting
diagram is shown as the right one.
The following tables list the function of each of the board's jumpers.
