Patton

The Model 2089F is Patton's first high speed RS-232 to RS-485 EIA-574 interface converter. The 2089F features a female DB-9 with terminal block. 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. The Model 2089 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...
