Setting Jumpers; Quick Reference For Jumpers - TYAN THUNDER X Manual

2.3 Setting Jumpers

In this manual, the terms "closed" and "on" are used
when referring to jumpers (or jumper pins) that are active;
"open" and "off" are used when referring to jumpers (or
jumper pins) that are inactive. See the Figure 2-1* for
examples of "on" and "off" pins and jumpers. The square
pin in the diagram is Pin 1.
Jumpers and pins are connected by slipping the blue plastic jumper connector
overtop of two adjacent jumper pins (indicated by 1-2 or 2-3). The metal rod
inside the plastic shell bridges the gap between the two pins, completing the
circuit. See Figure 2-2* for more example of pin connections.
Plastic Jumper Connector
* In the figures, the darkened areas indicate the location of the plastic
jumper connector.
