The Model 1004A 2/4 wire short range modem is the "next generation" replacement for our popular Model 1004. The Model 1004A still gives you up to 50 terminal drops over one (half duplex) twisted pair, and still supports async data rates up to 115.2 kbps. It also passes data plus one control signal in each direction, just like the Model 1004. However, the Model 1004A now gives you more flexibility, with extra configuration parameters: Two separate high/low impedance settings, "echo" on/off and selectable RTS/CTS delay are now standard, as well as selectable carrier control and a DCE/DTE switch. Also standard on the new Model 1004 is 600 wats per wire of Silicon Avalanche Diode surge protection (no need to add an "S" to the model number when ordering). The Patton Model 1004A- it's the same short haul you've come to depend on, only better!
