The Patton
2085 high speed RS-232 to RS-485 interface converter supports async
RS-232 data rates to 115.2 kbps over one or two unconditioned twisted
pair. Passing one control signal in each direction, the Patton 2085 can
handle up to 50 terminal drops in a multipoint polling environment. The
Patton 2085 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.
