1.0 WARRANTY INFORMATION
Patton Electronics warrants all Model 1012B 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 Patton
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. Patton Electronics specifically disclaims all
other warranties, expressed or implied, and the installation or use of this
product shall be deemed an acceptance of these terms by the user.
1.1 RADIO AND TV INTERFERENCE
The Model 1012B generates and uses radio frequency electromagnetic
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 1012B has been tested and found to
comply with the limits for a Class A computing device in accordance with
the specifications in Subpart B 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 1012B 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, re-orienting 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). In the event the user
detects intermittent or continuous product malfunction due to nearby high
power transmitting radio frequency equipment, the user is strongly advised
to take the following steps: use only data cables with an external outer
shield bonded to a metal or metalized connector.

2.2 DESCRIPTION
In a multi-point environment, the master transmits data to all of the
addressable slave devices (there can be up to 10 slave devices).
Typically the modem at the master site is set for
constant carrier
,
whereas the modems at the slave sites must be configured for
controlled carrier
. Automatic equalization and gain control ensure the
optimal performance for a specific environment. Environments vary in
the twisted-pair wire gauge, quality of the twisted-pair, the data rate,
length of the transmission line, number of slave devices on the circuit,
etc. The transformers eliminate problems caused by ground loops. With
all these features, the 1012B can be used in numerous types of
applications. Some of them are simple point-to-point between buildings,
multipoint applications, and point-to-point applications which require
passing a control signal from end-to-end.
The 1012B uses silicon avalanche diodes (SADs) for protection
against transients. With SADs, the clamping response is superior and
does not degrade in performance after transient “hits.” The
surge/transient protection protects the 1012B as well as the port to
which it is connected.
