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 synchronous/asynchronous serial ports while the SYNW57Oi adds two or four synchronous/ asynchronous ports. They are designed for applications requiring cost-effective communications. Each board and connector package is supplied with all the hardware and software needed for a complete board installation.
A complete list of SYNC/570 features and specifications is located in the appendices. !!xNc/57oi The SYNW57Oi communicates at Tl/El line speeds up to 5 Mbps. Each 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.
CHAPTER WO Protecting Your Equipment and Data Elect&xl Surge and Power Protection Lightning, electrical surges, and power fluctuations can damage your equipment and/or data through the power lines and/or the serial data lines. When electrical storms occur, the most effective method of protecting your computer system is to unplug your computer and peripherals, and disconnect all data and telephone lines.
Using a receptacle for only the computer and terminal also protects against data errors or equipment damage. Sharing the receptacle with noiseproducing 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.
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. Consult your local electronics or office supply distributor for static control products.

board before you install the board. Refer to Section 5 for switch settings. When you have set the switch, continue with the board installation below. If you are installing a SYNC/570 or SYNC/57Oi in a Micro Channel computer, proceed with the board installation. When the board is installed, configure it as described in Section 6. 4. Insert the SYNC/570 or SYNC/57Oi board into the mating motherboard socket. Push the board firmly into place. 5.
CHAPTER FIVE Setting the ISA SYNC/570 and SYNC/57Oi Switch Before installing the SYNC/570 or SYNC/57Oi in an ISA system, set the multi-segment switch on the board The setting of the switch selects the starting address of the block of I/O locations which the SYNC/570 or SYNC/57Oi uses. The board is shipped with a setting of 300H. Diagrams of commonly used I/O address switch settings begin on the following page.

CHAPTER SIX Configuring the Micro Channel SYNC/570 and SYNC/570i Configure the SYNC/570 and SYNW57Oi through your computers Micro Channel Programmable Options Select @OS) system, using data from the Digi Adapter Definition File (ADI on the diagnostic diskette. This system uses hardware registers, selected and loaded through software, to assign system resources to an expansion board.
f 3. Reboot the computer with the backup copy of your computer system’s reference diskette. The computer will show error 165 and beep twice. Continue as instructed. 4. Follow the instructions shown on the screen to select the mode necessary to manuaIly set the configuration--do not use the automatic amfIguration. (The instructions for manual configuration will vary for computers ma& by different manufacturers.) s.
CHAPTER SEVEN Connecting Peripherals Your application may specify the cable configuration required for connecting modems to a computer. If so, you should follow their recommendations. If cable configuration is not specified, you can use the cable type described in the appendix pertaining to your version of SYNC/570 or SYNC/57Oi. If you supply your own cables for SYNC/570 or SYNC/57Oi, Digi recommends shielded cables (15 pF or less capacitance per foot) for all installations.

CHAPTER EGHT Using the Diagnostics Disk The diagnostics diskette in conjunction with the loopback connector is designed to verify correct installation. Make a copy of this disk and store the originaL Should a problem develop in the future, you can run the diagnostics to locate the problem. ZEL Your system must be runntng DOS in order to use the diagnwicsprogram. NOTE The diagnostics tests one board at a time.
When IRQ and address selection are acceptable, the adapter memory is tested. ‘Ihe test does write/verify at every location with word accesses only. Each 16K memory window is selected and tested independently. Address and data buses are tested separately. The program then runs a window uniqueness test. A different, single word is written to each of the eight 16K windows; then the test reads each window to verify that the windows are indeed unique.
CHAPTER NINE In Case of Trouble BL WARNING Make sum your computer 13 turned off befom hstalltng or nvrwuing boar& When installhzg or removing boards, always use adequuteprecautions b4ch as a grvunding strap) top- electnxtattc damage. Test your SYNC/570 or SYNC/57Oi using the diagnostics disk provided If the SYNC/570 or SYNW7Oi passes all the tests, the problem is probably elsewhere. The symptoms of particular problems may vary between operating systems. Common problems are listed below.
Improper Grounding Make sure that every component in your system is properly grounded. Differences in ground potential between your computer and terminals can damage equipment. If your board fails the diagnostics or you are unable to isolate the problem, call Digi Technical Support @OO-344-4273) anytime between 8 a.m. and 6 p.m. Central Time (Monday through Friday). We can give you suggestions for things to try. Please have the following information ready when you call: Fill in information here . . . .
IfYou Have to Return a Board Sometimes our boards do have problems and have to be returned for service. In this case, you’ll need to call us for an RMA number. You must have an RMA number to return a board to Digi. The RMA number must appear on the outside of the package. Before calling for the number, make sure you can answer the following questions: t- 1. Where did you buy your board? If you bought from a dealer, you should go through the dealer to return the board.
