The Model 1008 is our first multipoint short range modem to fit in an ultra-miniature DB-9 package! Compatible with the new Model 1004A, the Model 1008 supports data rates to 115.2 kbps and distances up to 9 miles (14.5 Km) on 19 AWG @ 1200 bps over one or two twisted pair. Requiring no AC power or batteries for operation, the Model 1008 allows up to 50 terminal drops in a multipoint environment. The Model 1008 passes data, plus one control signal, in each direction. Five separate configuration parameters let you custom-tailor the Model 1008 to your particular application. And surge protection is standard!
