2.5 Setting jumpers You configure your card to match the needs of your application by setting jumpers. A jumper is the simplest kind of electric switch. It consists of two metal pins and a small metal clip (often protected by a plastic cover) that slides over the pins to connect them. To “close” a jumper, connect the pins with the clip. To “open” a jumper, 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.
2.6 CMOS clear function (JP1) Warning: Table 2-3: To avoid damaging the computer, always turn off the power supply before setting "Clear CMOS". Set the jumper back to normal before turning on the power supply.
2.7 Watchdog timer config. (JP2) An on-board watchdog timer reduces the chance of disruptions which EMP (electro-magnetic pulse) interference can cause. This is an invaluable protective device for standalone or unmanned applications. Setup involves two jumpers and running the control software. (Refer to Appendix A.
2.8 COM2 settings for RS-232/422/485 (JP3) Table 2-5: COM2 settings for RS-232/422/485 *RS-232 JP3 (JP3) RS-422 RS-485 1 2 1 2 1 2 3 4 3 4 3 4 5 6 5 6 5 6 * default setting 2.
