2.2 DESCRIPTION
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.
