Jumper Location - JHCTech KMDA-2702 User Manual

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 representative
before you make any changes.
Tip: How to identify the first pin of the interface or jumper, observe the text mark next to the plug socket,
it will be indicated by "1" or bold lines or triangle symbols; look at the pad on the back, the square pad is
the Pin 1; all jumpers have a white arrow next to pin 1.
