Acrosser AR-B1894 - Manual (Page 12)

2. Hardware Configuration Setting
This chapter gives the definitions and shows the positions of jumpers, headers
and connectors. All of the configuration jumpers on AR-B1894 are in the proper
position. The default settings shipped from factory are marked with an asterisk
( ).
In general, jumpers on the Mini ITX are used to select options for certain features.
Some of the jumpers are designed to be user-configurable, allowing for system
enhancement. The others are for testing purpose only and should not be altered.
To select any option, cover the jumper cap over (SHORT) or remove (NC) it from
the jumper pins according to the following instructions. Here, NC stands for “Not
Connect”.
