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.
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.

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.
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
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 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 equipment 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 grounding 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 magnetic

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.

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. The FCC requires the use of shielded cables to comply with
EMI/RFI
emission limits. In addition, cables that run long distances or
through electrically noisy areas are subjjct to voltage surges that can cause
data errors or equipment damage.
t
EIA-232-D specifies a maximum cable length of 50 feet. If you run cables
farther than 50 feet, you increase the risk of surge damage and data loss.
(However, using shielded cable of
lo-15 pP
capacitance per foot somewhat
lessens the risk of data errors.>

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
NOTE
Your system must be
runntng DOS
in
order
to use the
diagnwicsprogram.
The diagnostics tests
one board at a time. Although the active
board by
default is the ISA board at the highest I/O address or the Micro Channel
board at the highest slot number, you may change the active board. The
screen header indicates the active board and its address.
t
The tests will fail if there is an address or interrupt conflict If the
diagnostics cannot determine your switch settings, there is probably a
conflict. In this case, try other address and/or interrupt settings.
For an ISA system, the diagnostics program displays IRQ, the base memory
address, and the base I/O address. You may modify the address and IRQ
selections from the diagnostics. The IRQ must be active, and you must
select a non-zero address. If you cannot determine a setting, call
Digi
Customer Support for assistance.
For a Micro Channel system, the diagnostics program displays the current
POS registers which identify the IRQ, the base memory address, and the
base
I/O
address. If any of these parameters need to be
changed, repeat
the procedure in Section 6 beginning with Step 3 on Page
16.
If you cannot
determine a setting, call
Digi
Customer Support for assistance.

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.
When prompted, install the single channel
loopback
connector onto
line 1 (the lower connector for
Micro
Channel).
The
wiring diagram
for the
loopback
connector is in the appendix pertaining to your
version of
SYNC/570

The diagnostics program tests the
control and data lines. The control line

test is the default single
channel chained-block
DhL4
transfer mode test. When the line 1 tests
are complete, install the
loopback
connector on line 2 (the upper
connector for Micro Channel). The tests will be repeated for line 2.
The diagnostics program also tests the ability of the card to generate
interrupts by way of internal data loopbacks. It tests all found ports.
For example, a 4 port board will prompt you to move the
loopback
connector when performing the external data and control signal tests.
The internal and external tests are run at the maximum supported bit
rates for their respective interfaces. On the internal tests, all available
channels are
run
simultaneously at the maximum bit rate to help
resolve arbitration and memory bandwidth issues.

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.
Addxess/Interrupt
conflicts
All devices in your system must have unique addresses that must not
overlap. The memory location must be outside the caching memory
range. If you think you have a conflict problem, try alternate settings.
Inconsistent Baud Rate
The
baud rate and other parameters chosen via the operating system
must be the same for the SYNC/570 or
SYNC/57Oi
and the peripherals
connected to it.
No Handshaking Signals
Some peripheral devices may need some or all of the handshaking
signals that SYNC/570 or
SYNW57Oi
supports.
Iucomplete
or Incorrect
Iustallation
Some operating systems require that an installation procedure be run
before SYNC/570 or
SYlW57Oi
is recognized Refer to your operating
system user’s manual. Verify correct SYNC/570 or
SYNW57Oi
hard-
ware installation.

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:
1.
2.
3.
t-
4.
Where did you buy your board? If you bought from a dealer, you
should go through the dealer to return the board. If you bought it
from
Digi,
you can deal directly with us for repair.
What is your boards serial number, revision level number, and date
of purchase?
Have you followed the checklist at the beginning of this section and
tried all of the steps? We’ve found that these procedures eliminate
most problems encountered during installation.
Have you contacted the dealer from whom you originally purchased
the board for his advice and assistance?
Your
Digi
board is one of the most reliable parts of your multiuser system.
As a matter of fact, if you purchase a board from us and it doesn’t work in
your application, or if you decide not to keep it for any reason during the
first 30 days, we will refund your money. But remember, we’re here to help
in any
casecause
our ultimate goal is to keep your system up and
running, and to keep you a satisfied customer.

The
SYNC/570
has two high
density
15pin
D-subminiature female port
connectors. The connectors provide an
EIA 232D
interface and serial data
transmission and reception.
Your application may specify the cable configuration required for
connecting modems to a computer. If so, you should follow their recom-.
men&&ions.
If cable configuration is not specified, you can use the cable
types discussed below. Cables for use with synchronous modems need a
minimum of eleven wires plus a shield.

The
DB-15 connectors are
compatiile
with HA-232-D devices. Figure 1
