Omni Board Jumper Settings - Geometrics SmartSeis Maintenance Manual

2.3.1 OMNI board jumper settings

As previously mentioned, a jumper is a connector that, when placed over two jumper pins,
provides continuity. On the OMNI board, jumpers are used to set various functions on the
board. The OMNI board jumpers range from JP1 to JP13. Tables 3, 4, and 5 outline the
jumpers and IRQs (computer interrupt settings) associated with each function and the
appropriate settings. Table 6 outlines the setting for switch S1.
