The Patton Model 1205 sync modem eliminator lets two synchronous hosts communicate with each other in the same room for a fraction of the cost of a pair of high speed modems or line drivers. Supporting sync data rates of 32, 48, 56, 64, 72, 112, 128 and 144 Kbps, the Model 1205 can be configured to emulate dial-up or leased line service. Maximum distance between the connected hosts is 300 feet. Timing can be set for internal, external, or receive recover clock, and all necessary data, clocking and control signals are supported. The Model 1205 implements the V.35 electrical interface on DB-25 female connectors, according to the EIA-530 Standard (DB-25 to M/34 adapter cables are available from Patton.) Operating power is drawn from both V.35 interfaces, or provided via an AC adapter.
