  1. Allen Bradley 1747-UIC DH485 Issues

    That is the document for future reference :) DH-485 Cables used with SLC-500 processors and the 1747AIC.pdf

    I found another document about the cables required and it states it requires an external power source.. this is probably my problem. I have contacted a rep to find me the correct cable. Thanks again. If you do find any other information, can you please still send it through.   Cheers, Craig

    Thank you. I'm not sure if it is this one ( https://www.plccable.com/allen-bradley-slc-1747-c13-dh485-to-be-used-with-1747-uic/ ) It shows pinout on that page mid way down..

    Yeah, I couldn't find that setting to check the RSS files baud rate until after I tried changing it, so thanks! I've made one, its just missing the orange/white core, right? That is what I found using  https://www.plccable.com/allen-bradley-slc-1747-c13-dh485-to-be-used-with-1747-uic/ It still seems to not load comms..

    I used this process to change baud rate from 19200 to 9600 and reversed as well.. https://rockwellautomation.custhelp.com/app/answers/answer_view/a_id/493842/redirect

    No, it shows 19200.. but I have tried with both

    Thanks for the reply so promptly. The program hasn't had an edit since 2009, and once used an 'AB_PIC-1' driver, but I can change that in the 'controller properties' in rslogix500... We have since updated computer and cable systems.. I found online that the 1747-UIC is auto configured to 19200 out of the box, and most likely needed to be 9600, which I have changed using link below. https://rockwellautomation.custhelp.com/app/answers/answer_view/a_id/493842/redirect Yeah the selector switch is in the up position for DH485 :) Auto-browse is deselected also. I do get the 'USB' led and the 'OK' led on the 1747-UIC adaptor indicating, however the DH485 led just pulses/ flashes quickly as if its trying to communicate but no prevail still...

    Hi there, I am having issues connecting my computer to our SLC 5/02. We have a genuine Allen Bradley 1747-UIC USB to DH485 adaptor, I have read into it a fair bit and have tried many different things. I have removed pin 3 configurations from the ethernet (DH485) as advised previously.. I have tried many drivers to get it to work to no prevail. I cant even change the CPU over to a 5/03 as I cant guarantee the program we have a copy of is the exact one in the CPU, therefore I cant just change to a different unit and establish comms that way. Does anyone have a step by step guide to connecting the 1747-UIC to the PLC? Many youtube clips dont seem to work for me like they do in the videos.   Thanks a lot in advance if you can help!
