6. Interrupt Level (IRQ)

The DS-200/300 allows the use of any interrupt level in the range IRQ2 to IRQ7, IRQ10 to IRQ12, IRQ14, or IRQ15, selected using jumper block J3 (for Serial 0) or J4 (for Serial 1). In Figure 12, the factory default settings for Serial 0 and Serial 1 are shown. To select a different IRQ, move the jumper to the appropriate position on J3 or J4.
