Patton 1040 RS-232 Self-Powered Line Driver, Short Range, Modem with Surge Protection

The Model 1040 from Patton Electronics is a self-powered, miniature short-range modem for RS-232 signals. Operating asynchronously or synchronously, the Model 1040 supports data rates to 38.4 Kbps and distances to 12 miles (19.3 Km). It operates over 2 or 4 wires in point-to-point or multipoint environments. In synchronous mode, the 1040 supports internal, external, or receive loopback clocking.

The model 1040 incorporates two V.54 and two V.52 BER test modes, which can be activated via the RS-232 interface. Built-in LEDs let you monitor test mode operation. Additional peace of mind comes from knowing that it has transformer isolation and surge protection to guard against data loss and damage from voltage transients. The model 1040 plugs directly into the RS-232 interface. Twisted pair wiring is connected using RJ11, RJ45, or terminal blocks. The unit draws power from the RS-232 signals and requires no external power source.
