Paul Chang Posted April 16, 2020 Share Posted April 16, 2020 Dear Sir, Is it possible to change RS485 to RS422 interface? How to set it to RS422 full duplex? Thank you. Best Regards, Paul Link to comment Share on other sites More sharing options...
JColvin Posted April 16, 2020 Share Posted April 16, 2020 Hi @Paul Chang, Digilent doesn't have any specific guidelines in terms of converting the module, though based on the IC's datasheet, https://www.analog.com/media/en/technical-documentation/data-sheets/ADM2582E_2587E.pdf, there will need to be some different resistances on the differential output voltage (page 4 of the datasheet). I would also recommend looking at the also referenced AN-960 Application Note from Analog Devices, though the physical layer is described in ANSI/TIA/EIA-422-B.
