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 1180 generates and uses radio frequency energy, and if not installed and used properly—that is , in strict accordance with the manufacturer’s instructions—ma y cause interference to radio and television reception. The Model 1180 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 1180 does cause interference to radio or television reception, which can be determined by turning the power off, 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).

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 1180. Technical Service hours: 8AM to 5PM EST, Monday through Friday.

2.2DESCRIPTION

The Model 1180 Single Fiber Short Range Modem accomplishes point-to-pointRS-232 communication over a single optical fiber. Supporting synchronous data rates to 256 Kbps, and asynchronous data rates to 38.4 Kbps, the Model 1180 automatically adapts to hardware or software flow control. Synchronous timing can be set for internal or external clock.

The Model 1180 features extended data rate circuitry that allows for single fiber distances between 2.5 and 5 Km. Optical fiber may be connected to the Model 1180 using an ST or SMA type interface. The Model 1180 encodes the electrical signal using 3B4B modulation. The electrical signal is then converted to an optical signal and transmitted using an 880 nm light emitting diode.

The Model 1180 features two test modes: local and remote loopback. These loopback tests are activated via a front panel switch. The local loopback test is used to evaluate the RS-232 to modem connection. The remote loopback test is used to evaluate the condition of the connection between the modems.
