The Patton
2089 is Patton’s first 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 Patton 2089 passes one
control signal in each direction. The Patton 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 for operation. The Patton 2089 has five
configuration parameters, allowing the unit to be “fine tuned” to a
variety of point-to-point or multipoint applications. Silicon
Avalanche Diode surge protection is standard as well. Amazing!
