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.

1.2 SERVICE

All warranty and nonwarranty repairs must be returned freight prepaid and insured to Patton Electronics. All returns must have a Return Materials Authorization number on the outside of the shipping container. This number may be obtained from Patton Electronics Technical Support: (301) 975-

2.2DESCRIPTION

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.
