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. Each board and connector
package is supplied with all the hardware and software needed for a
complete board installation.
The Hitachi HD64570 Serial Communications Adapter WA) provides a
highly-integrated advanced communications subsystem for the SYNC/570
and the SYNW57Oi. It further maximizes synchronous communications
performance by using protocol-specific features to minimize driver
overhead.
The onboard memory of both the SYNC/570 and the SYIW57Oi is directly
addressable by both the system and the SCA’s DMA. Program-initiated DMA
transfers operate at DMA/memory speed independently of other system
activity. This architecture provides low system overhead and high
performance.
The optional OEM software lock ensures that OEM software will operate
only with OEM-supplied boards.
SYNW57Oi (and SYNC/570 optionally) includes SurgeBlock”, which is
designed to protect the board and the computer in which it is installed
against damage from data line surges.
SYNC/S70
Multiple SYNC/570 boards may share a common memory window. Micro
Channel boards may also share a common interrupt request line.
The two ports of the SYNC/570 each have a high density DB-15 connector
to connect any device with an EIA-232-D interface to your computer. The
board operates at line speeds from 4800 baud to over 115K.

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.
Multiple SYNC/57Oi boards may share a common memory window. Micro
Channel boards may also share a common interrupt request line.

Chapter One: Introduction

CHAPTER WO
Protecting Your Equipment and Data
Elect&xl Surge and Power Protection
Lightning, electrical surges, and power fluctuations can damage your equip-
ment and/or data through the power lines and/or the serial data lines. When
electrical storms occur, the most effective method of protecting your com-
puter system is to unplug your computer and peripherals, and disconnect
all data and telephone lines.
To protect against lightning, electrical surges, and power fluctuations, Digi
recommends uninterruptible power supplies CUPS), power line filters, and
surge protectors for every installation.
A UPS can provide protection from electrical surges and fluctuations in the
power supplied to the computer. However, it does little good to protect the
main console if you have no protection on the other devices attached to the
system. Power line filters protect against electrical surges and transient
spikes. Some filters even have a shutdown feature that drops power to the
device if voltage drops below a preset level. This prevents the spikes and
surges caused by the typical “off and on” electrical problems that occur
during a thunderstorm. AC line filters should be used with all electrical
devices connected to a computer system, no matter how small or simple.
The interface cables themselves present another potential danger. Nearby
lightning strikes can induce high-voltage surges into the cables. Machinery,
especially commercial machines with electric motors, often generates elec-
trical noise that can be picked up by cables and cause data errors or
equipment damage. Digi includes SurgeBlock on every SYNCY57Oi and
optionally on the SYNW70. SurgeBlock clips fast-rising peak voltages to
help protect against spikes over twenty-five volts caused by lightning,
static, or induced voltage. For maximum protection we recommend surge
suppressors on the peripheral end of all serial cables.
Cables running long distances and/or through electrically noisy areas are
subject to noise pickup that can cause data errors or equipment damage.
Destructive power surges can also enter through modems via telephone
connections. Filters made specifically for this purpose should be included
on all telephone line connections. 3

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 Techniques
Many terminals and computers are dependent on earth ground to set a
reference for signal ground. Improper grounding or differences in ground
potential between your computer and terminals can damage your equip-
ment or even create a safety hazard. Consequently, you should make sure
that every component in your system is properly grounded.
Connect your computer and all terminals and other peripherals to three-
pronged grounded receptacles, making sure that the receptacles are wired
properly. If you must use three-prong to two-prong adapters, make sure
that the adapter ground tabs are properly grounded.
A proper chassis ground guarantees that no dangerous voltages exist on
terminal frames. Proper grounding also helps cancel noise that can other-
wise be induced on the frame or equipment.
Local electrical codes may also dictate special grounding arrangements.
Your electrician can make sure that your installation complies with all
applicable codes. If you have any doubt about the integrity of the ground-
ing system in your location, have the system checked by a licensed
electrician.
Static Protection
Your computer’s case not only houses its family of computer components,
but it also protects these sensitive electronic components from stray mag-
netic @VII) and electrical WI, static) fields.

Chapter Two: Protecting Your Equipment and Data

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.
If you would like an overview of grounding and static protection theories
and techniques, you can obtain a copy of Federal Information Processing
