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 required driver tests.

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. From the standard:

Because schemes providing this bias place an additional electrical load on transmitters, all controller and responder transceiver designs must be tested for conformance. While these tests are simple, construction and verification of a test set can be time consuming and expensive.

Goddard Design now offers a three PCB set that allows any EIA driver and biasing scheme to be tested to the requirements of Appendix F in a matter of minutes.
The test set includes:
A standard test load card that implements the four required tests
Two DUT test cards that take a standard 485 transceiver in an 8 pin DIP package. An adapter to SO8 or SOP8 packages is available. One card comes with the E1.20 default bias network installed, the other card is left open for user designs.
Three universal switching powers supplies are included.
All the user needs to provide is one adjustable bench power supply capable of supplying the DUT, and a good quality DVM.
