Self-Powered, High Speed, Multipoint, DB-9 and DB-25, Short-Haul Modems
Models 1008 and 1004A
The Model 1008 and Model 1004A 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, these Short Haul Modems allow up to 50 terminal drops in a multidrop environment.
The 1008 and 1000 pass data, plus one control signal, in each direction. Five separate configuration parameters let you custom-tailor the SRMs. These include two separate high/low impedance settings, echo on/off and selectable RTS/CTS delay, as well as selectable carrier control and a DCE/DTE switch.
And 600 watts per wire of Silicon Avalanche Diode surge protection is standard !
