Greg Gogates Posted December 28, 2022 Posted December 28, 2022 I just bought an ETSY and didn't realize that I needed an adapto to connect to my 2413S. The recommended one is sold out so I either have to wait or make do. I already have a USB to DB9 serial port adaptor and a old Cisco router blue admin port cable that does RJ45 to DB9. I'm not sure how its pinned, and its molded so I am stuck. It would be nice if UD could publish the RJ45 to DB9 pinout configuration so that I can make my own considering that I do not have another choice at this point in time. TIA Greg

Techman Posted December 28, 2022 Posted December 28, 2022 The wiring diagram is posted on the forum, you'll need to search for it. The box that the PLM came in has a DB9 to PLM cable stored in the bottom of the box. If you still have it then you just need a serial to USB convertor, which is available on Amazon.
CLU Posted December 30, 2022 Posted December 30, 2022 I was able to get my PLM to connect. Make sure to double check the manual for 2413S. Some previous posts have the TX/RX reversed This worked for me: RJ45 Pin1 --> RS232 RX (2) RJ45 Pin8 --> RS232 TX (3) RJ45 Pin7 --> RS232 GD (5) 1
Brian H Posted December 31, 2022 Posted December 31, 2022 I think some users using a network adapter. May have gotten the send and receive signals reversed or incorrectly wired. Accidentally connected the TTL signals to something. If using a 2412S RJ45 Pin2 is unregulated +12VDC, around +18V in my tests. The quick sheet with the PLM had in my opinion easily to make an error.
