  • Page 6: Introduction

    Introduction The OME-PIO-D144 consists of one D-Sub 37 & five 50-pin flat-cable connectors. There are three 8-bit ports - PA, PB & PC - in each connector. Every port consists of 8-bit programmable D/I/O. So the OME-PIO-D144 can provide 144 channels of TTL-compatible D/I/O.

  • Page 13 Note: When the interrupt is active, the user program has to identify the active signals. These signals maybe all active at the same time. So the interrupt service routine has to service all active signals at the same time. OME-PIO-D144 User’s Manual (Ver.2.1, Sep/2001) CN1_PC0 & CN1_PC1 are return to normal at the same time.
