3.1 Jumper Locations and Orientation

The configuration jumpers on the Async 232↔422/530 Card and the
rear interface card allow you to configure the function of both front-panel
"Carrier Detect" LEDs, as well as the rear interface card CD signal. Figure 3-2
shows the orientation of these jumpers. Notice that each jumper can be either
on pegs 1 and 2, or on pegs 2 and 3. Note: Pin 1 is always located on the top
or left side of the jumper set.
