  • Page 7: Introduction

    CHAPTER ONE Introduction The Digi SYNC/570 and the SYNCY57Oi are high-performance expansion boards for ISA or Micro Channel computers. The SYNC/570 adds two syn- chronous/asynchronous serial ports while the SYNW57Oi adds two or four synchronous/ asynchronous ports. They are designed for applications requiring cost-effective communications.
  • Page 8 HI64570 chip supports two synchronous/asynchronous ports and four channels of DMA as well as interrupt and timer logic. Digi SYNC/57Oi is available with several interface options. Interface specific information (interface setting instructions, cables, connector information) can be found in the interface appendices.

  • Page 9: Protecting Your Equipment And Data

    To protect against lightning, electrical surges, and power fluctuations, Digi recommends uninterruptible power supplies CUPS), power line filters, and surge protectors for every installation.
  • Page 10 Using a receptacle for only the computer and terminal also protects against data errors or equipment damage. Sharing the receptacle with noise- producing devices such as fax machines, printers, calculators, and heaters may allow noise pickup. Grounding T e c h n i q u e s Many terminals and computers are dependent on earth ground to set a reference for signal ground.
  • Page 11 Make sure that you are working in a static-controlled area which includes at least a conductive benchtop mat or chair mat that is electrically connected to earth ground. Conductive wrist straps in conjunction with ground cords provide extra protection for handling electronic components. Always store and/or move individual printed circuit boards in a conductive bag.
