  • Page 3: Chapter 1: Introduction

    Address Switch Setup The 2IQEC2/4 cards use a 7-position DIP switch to program the binary I/O address of each port on the card. The 2IQEC2/4 cards are factory configured for address 0x300 with no IRQ. If you plan on installing the 2IQEC2/4 with these settings, check the switch settings to ensure that they did not get inadvertently changed during shipping.

    The 2IQEC2/4 card allows the use of interrupts (IRQ) 2-7, 10-12, 14, and 15. This interrupt is shared with all the channels. To determine the channel that caused the interrupt, the interrupt service routine must read the address located at the base address plus 8.
