Description

The Patton 2089 is a high speed EIA-574 (RS-232 on a DB-9) to RS-485 interface converter. Supporting async data rates to 115.2 kbps over one or two unconditioned twisted pair, the Model 2089 passes one control signal in each direction. It can handle up to 50 terminal drops in a multipoint polling environment; yet it is small enough to plug directly into a DB-9 serial port…and requires no AC power or batteries for operation. There are five configuration parameters, allowing the unit to be precisely to a variety of point-to-point or multipoint applications. Surge protection is included with this unit.
