The EVAL-RS485HDEBZ is an evaluation board which allows quick and easy evaluation of half duplex RS485 transceivers with standard 8 lead SOIC footprints. The evaluation board allows interfacing via screw terminal block to digital I/O for driver input (DI), driver enable (DE), receiver enable (RE) and receiver output (RO). Bus signals A and B (half duplex bus) can be connected to a bus screw terminal block. One or two termination resistors can be connected to A and B via jumper settings, in order to evaluation the half duplex RS485 driver and receiver. Footprints are provided for pull up and pull down (biasing resistors) on the bus.
