are high-performance expansion boards for ISA or Micro Channel computers. The SYNC/570 adds two syn­chronous/asynchronous serial ports while the
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
provides a
highly-integrated advanced communications subsystem for the SYNC/570
and the
It further maximizes synchronous communications performance by using protocol-specific features to minimize driver overhead.
The
memory of both the SYNC/570 and the
is directly
addressable by both the system and the
DMA. Program-initiated DMA
transfers operate at
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.

Channel boards may also share a common interrupt request line. The two ports of the
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

CHAPTER
Protecting Your Equipment and Data
Surge
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,
recommends uninterruptible power supplies
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.
includes

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 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
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
and electrical
static) fields.

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
supply distributor for static control products.

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.
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
Customer Support for assistance.
For a Micro Channel system, the diagnostics program displays the current

base
