Synchronous Communications
Controller
Installation Instructions
Introduction
Digi's four port Universal Interface Card can auto-
matically determine, from the cable, the interface
bus type to use with the peripheral device. That is,
you can select an interface type for the adapter
(V.35, X.21, EIA-530, or EIA-232) just by connect-
ing the appropriate cable between the peripheral
device and the quad-cable attached to the adapter.
Each of the ports on the quad cable can use the same
or a different type of interface cable, giving you the
flexibility to use one adapter to connect to peripher-
als with different interface types.

Installing the Adapter
Before you begin
Before installing the SYNC/570i adapter and daugh-
ter card, you should do the following:
• Be sure that you have the correct cables for the
interface type(s) you will use with the SYNC/
570i. Depending on the package you ordered,
you will have up to four peripheral cables in
addition to the quad-cable.
• Record the adapter’s serial number (located
under the part number label as shown in
Figure 1), which will enable Digi to provide you
with better service, should the need arise.
• Unplug power from the PC.
• Discharge static electricity from your body by
touching a grounded surface (prior to handling
the adapter).
• Put a ground strap on to ground yourself. (If one
is not available, ground yourself by touching an
unpainted metal surface, such as the computer’s
chassis.)

Installation Procedure
1.
Install the adapter.
a.
Remove the computer’s cover.
b.
Locate an available PCI slot in your computer
and remove the slot plate.
c.
Insert the adapter into the slot and screw the
endplate to the computer chassis. The endplate
must be screwed into the computer chassis to
remain in compliance with Part 15 of FCC
rules.
d.
Replace the computer’s cover.
2.
Connect cables. (See Figure 2.)
a.
Attach the end of the quad-cable with the HDD
78-pin connector to the adapter port.
b.
Attach peripheral cables to the HDD 26-pin
connectors on the end of the quad cable.
Because the HDD-26 end of the peripheral
cables do not have a label, take care when
making this connection. For example, both
ends of the X.21 peripheral cable look similar.
(You need not use all of the ports on the quad-
cable.)
c.
Attach the other end of the peripheral cables to
peripherals. (Additional cabling information
is provided on this card.)
3.
Boot the computer.
Note:
The LEDs showing through the faceplate
on the adapter will not light until a driver
is loaded and the adapter initialized. With
the Digi driver loaded, the green LED will
light to indicate that the adapter is in a
“ready” state. The amber LED will light
when data is passed to the peripheral
device.
4.
Run Digi’s diagnostics program.
The SYNC/570i PCI diagnostics are supplied on a
diskette that is shipped with the adapter. You
should run the diagnostics to verify that you can
communicate with the peripheral devices. Refer to
the text file on the diskette for information on
using the diagnostics.
What next?
Install and configure the software for the Digi
SYNC/570i PCI Board.
Usage Note
• If you change the interface of a port (by chang-
ing the interface cable) while your system is up,
the new interface may not be recognized until
the driver is restarted.
If you have a problem
• If you have a problem booting your system after
installation of your SYNC/570i adapter, you
should call Technical Support for assistance.
