The Patton Model 1012BFR11TB asynchronous short range modem is ideal for multidrop environments or for applications requiring hardware control signals. Attaining DC isolation through custom-designed ferrite core transformers, the Model 1012B operates effectively between buildings. In a point-to-point application, the Model 1012B will operate full or half duplex up to 6 miles (9.7 km). Supporting data rates to 57.6 kbps, the Model 1012B requires no AC power for operation. 600 Watts per wire of Silicon Avalanche Diode surge protection on the line side is now standard.
