1.0 WARRANTY INFORMATION

B&B Electronics warrants all Model 2010 components to be free from
defects, and will—at our option—repair or replace the product should it fail
within one year from the first date of shipment.

This warranty is limited to defects in workmanship or materials, and
does not cover customer damage, abuse or unauthorized modification. If
this product fails or does not perform as warranted, your sole recourse shall
be repair or replacement as described above. Under no condition shall B&B
Electronics be liable for any damages incurred by the use of this product.
These damages include, but are not limited to, the following: lost profits,
lost savings and incidental or consequential damages arising from the use
of or inability to use this product. B&B Electronics specifically disclaims all
other warranties, expressed or implied, and the installation or use of this
product shall be deemed as user’s acceptance of these terms.

1.1 RADIO AND TV INTERFERENCE

The Model 2010 generates and uses radio frequency energy, and if not
installed and used properly—that is, in strict accordance with the
manufacturer's instructions—may cause interference to radio and television
reception. The Model 2010 has been tested and found to comply with the
limits for a Class A computing device in accordance with the specifications
in Subpart J of Part 15 of FCC rules, which are designed to provide
reasonable protection from such interference in a commercial installation.
However, there is no guarantee that interference will not occur in a
particular installation. If the Model 2010 does cause interference to radio or
television reception, which can be determined by disconnecting the RS-232
interface, the user is encouraged to try to correct the interference by one or
more of the following measures: moving the computing equipment away
from the receiver, reorienting the receiving antenna and/or plugging the
receiving equipment into a different AC outlet (such that the computing
equipment and receiver are on different branches).

1.2 SERVICE

All warranty and non-warranty repairs must be returned freight prepaid
and insured to B&B Electronics. All returns must have a Return Materials
Authorization number on the outside of the shipping container. This number
may be obtained from B&B Electronics Customer Service at (815) 433-

Packages received without an RMA number will not be accepted.

5100.

B&B Electronics' technical staff is available to answer any questions
that might arise concerning the installation or use of your Model 2010.
Technical Service hours: 8 AM to 5PM CST, Monday through Friday.

2.0 GENERAL INFORMATION

Thank you for your purchase of this B&B Electronics product. This
product has been thoroughly inspected and tested and is warranted for one
year parts and labor. If any questions or problems arise during installation
or use of this product, please do not hesitate to contact B&B Electronics
Technical Support at [phone].

2.1 FEATURES

• Conforms to CCITT V.14 and V.22 standards

• Adapts asynchronous terminals to synchronous modems and

multiplexers

• Allows character lengths from 8 - 11 bits

• Requires no AC power or batteries

• Data rates to 19.2 Kbps

• Automatically adjusts synchronous data rates

• Miniature size

• Accepts external clocking

• Made in the USA

2.2 DESCRIPTION

The Model 2010 converter gives asynchronous hardware access to the
high speed capabilities of synchronous modems or multiplexers. The Model
2010 plugs directly into the asynchronous RS-232 DTE port and connects
via RS-232 cable to the synchronous DCE device.

Drawing power from the RS-232 interface, the Model 2010 needs no
AC power or batteries to operate and supports data rates to 19.2 Kbps.
Because the Model 2010 automatically adjusts the synchronous data rate
to match the asynchronous DTE's output rate, no data rate strapping is
necessary. The Model 2010 derives clocking externally from the clock of
the synchronous DCE, and imposes no limit on data block size. Characters
may be up to 11 bits long.

Measuring only 3.2" x 2.0" x .75", the Model 2010 is housed in a sturdy
ABS plastic case. It comes fully equipped with a DB-25 male connector and
a DB-25 female connector.
