The Patton Model 1010B async, 4-wire, transformer isolated short range modem is the best choice for data-only RS-232 connections between buildings. Capable of distances up to 9.5 miles (see tables below), the Model 1010B has two jumper selectable modes: High Speed mode supports data rates from 2400 bps to 115.2 kbps.
