2.2DESCRIPTION

The Patton Model 1050 AC Powered Asynchronous Short Range Modem is to our AC powered short haul line what the Model 1000 is to our interface powered line–a basic short haul at a great price! And the Model 1050 has the key features you need: optical isolation, a local loopback test mode, LED indicators and a DCE/DTE switch. The Model 1050 supports asynchronous RS-232 data rates to 38.4 Kbps. Distances of 7 miles (11.2 km) (@ 1200 bps) are attainable over two 24 AWG (.5mm) twisted pair.

Housed in an ultra-compact metal enclosure, the Model 1050 offers a choice of line connections: both external RJ-11 jack and internal terminal block are provided. On the RS-232 side, a female DB-25 is standard. The Model 1050 is designed for point-to-point or multipoint applications, and is also compatible with the Patton 1060 and 1226 short hauls.

3.0 CONFIGURATION

The Model 1050 may be configured for a wide variety of asynchronous RS-232 applications. This section will tell you how to access and set the internal DCE/DTE switch and the internal carrier control strap. WAIT. Before attempting to re-configure the Model 1050, check the Default Configuration Table (below) to see if the factory settings are correct for your application.
