Overview
--Image: RACKABLE! Rack Mount Available -- The Model 2084 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

The Model 2085 provides high speed RS-232 to RS-485 conversion over one or two unconditioned twisted pair. Otherwise, the Model 2085 has the same features and specifications as the Model 2084.

Model 2086 includes optical isolation along with the same set of features provided with the Model 2085. The Model 2086 requires an external power supply.

Product Highlights

Rack Mountable Units, Too!These rack cards each contain two converters, so you can fit 32 converters in a 19" rack.
