This warranty is limited to defects in workmanship or materials, and does not cover customer damage, abuse or unauthorized modifi- cation. 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 consequen- tial 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 1012AR 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 1012AR 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 interfer- ence will not occur in a particular installation. If the Model 1012AR does cause interference to radio or television reception, which can be determined by disconnecting the RS-232 interface, the user is encour- aged 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 equip- ment 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 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 Service at (301) 975-1007. Packages received without an RMA number will not be accepted.
Patton Electronics' technical staff is also available to answer any questions that might arise concerning the installation or use of your Model 1012AR. Technical Service hours: 8AM to 5PM EST, Monday through Friday.

2.2DESCRIPTION
The Patton Model 1012AR asynchronous short range modem was designed for point-to-point or multidrop applications requiring hardware handshaking. In a multipoint environment, the master transmits data simultaneously to up to 10 addressable terminals. The terminals con- tend for the main channel by activating RTS (pin 4). Automatic equal- ization and gain control ensure the accuracy of transmitted data.
Built-in transformers eliminate much of the noise which can occur in commercial buildings. These transformers also eliminate ground loops caused by differences in reference ground. Consequently, the Model 1012AR may be used to extend RS-232 (TIA-561) distances in environments where connected equipment is located in different build- ings.
The 1012AR uses the latest in bi-directional, clamping, transient suppressors to protect itself and connected equipment against harmful transient surges. These suppressors can dissipate 600W per wire at
1.0mS. Response times are typically 1.0 pS from 0 to the nominal breakdown level of 6.8 volts.
