A RDM Transceiver Qualification Tester

Goddard Design is proud to introduce an important test tool for anyone designing or verifying a new E1.20 (RDM) design. Our RDM Driver Qualification Test Set simplifies the driver tests required by the Standard.
If you are designing an RDM device, the selection of the line driver is not as simple as it once was. Just because an integrated circuit is labeled as a EIA485 driver does not mean that it is appropriate for RDM use. Electrical requirements have been added to increase the reliability of the protocol. For the purposes of E1.20 (RDM) the line transceiver IC and any bias components are jointly considered to be the line driver, and together must be qualified to drive the EIA485/E1.20 line.
