Configure the UNO-430 to match the needs of your application by setting jumpers. To
close a jumper, you connect the pins with the clip. To open a jumper, you remove the
clip. Sometimes a jumper will have three pins, labeled 1, 2 and 3. In this case you
would connect either pins 1 and 2, or 2 and 3.
The jumper settings are schematically depicted in this manual as follows.
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. Generally, you
simply need a standard cable to make most connections.
UNO-430 mainboard contains a jumper that can erase CMOS data and reset the sys-
tem BIOS information. Normally this jumper should be set with pins 1-2 closed. If you
want to reset the CMOS data, set CMOS1 to 2-3 closed for just a few seconds, and
then move the jumper back to 1-2 closed. This procedure will reset the CMOS to its
default setting.
