Bidirectional data

conversion between your

PC and RS-485

equipment.

upporting speeds of up to

115.2 Kbps at a distance

of up to 4000 feet (1219

meters), these Cards operate

half- or full-duplex, over 2- or

4-wire unconditioned

twisted-pair wire.

They convert between

RS-232 Comm ports on PCs

and one or more RS-485

devices, including industrial

numerical-control and data

acquisition equipment (for

example, data loggers,

conveyor belts, and milling

machines).

Set the RS-485 side

impedance high for

multipoint applications, or

low for point-to-point

applications. The Card

supports both.

NOTE: The Cards are

compatible with the Async

232

↔

485 Converter (IC476A,

IC477A, IC478A).
