Chapter 2 Jumper and Switch Settings
Shared IRQ Selection (JP3)
Select an IRQ which is not in use by another card in the system. If you are installing
more than one PCM-3618, set them to different IRQ numbers. Jumper Bank JP3
controls the card IRQ. Simply place jumper on desired pin head.
Independent IRQ Mode
Interrupt Status Register Setup (SW1, Vector Address)
This feature on the PCM-3618 is utilized in the shared IRQ. When data arrives at one
of the eight ports, an interrupt will be generated in the interrupt register. The PC soft-
ware can read this, and identify immediately which port generated the interrupt. This
saves time and makes programming easier. When a data bit of the interrupt status
register is set to 0, the corresponding channel is selected to generate an interrupt. If
the bit is 1, then no interrupt is generated. DIP switch SW1controls the card's inter-
rupt status register, as shown in the following table.
Port Base address (SW2)
Base Address A3 A4 A5 A6 A7 A8 A9
200-207 X X X X X X O

Note! If your CPU module or card has serial interface ports, you will need to
adjust the I/O port addresses (or disable the ports) to avoid conflicts.
