The Patton Model 2085M-25F high speed RS-232 to RS-485 interface converter supports async RS-232 data rates to 115.2 kbps over 2-wires. Passing one control signal in each direction, the Model 2084 can handle up to 50 terminal drops in a multipoint polling environment. The Model 2084 has five configuration parameters, allowing the unit to be "fine tuned" to a variety of point-to-point or multipoint applications. In addition, Silicon Avalanche Diodes provide 600 watts per wire of protection against harmful data line transient surges.
