2.3 Jumper Settings

Simply lift off the jumper's cap and place it on the
appropriate pair of pins (to activate/enable) or put it over the
pin (to deactivate/disable). The location diagram in Appendix
A and Appendix B will assist you in locating these jumpers.

2.3.1 JP9 (IRQ Level Selection)

JP9 selects the IRQ level (Interrupt Request), numbered from
3 through 12. The CH#1 IRQ select is located on the upper
pin row, whereas CH#2 is located at the lower pin row
position. For instance, if the I/O port of Channel #1 is set to
Hex 3F8 (COM1) and Channel #2 to Hex 2F8 (COM2) then the
jumper JP9 must be selected respectively. See the setting of
JP9 on Figure 1.
