ErikN Posted Thursday at 04:23 AM Posted Thursday at 04:23 AM Hi all I have a Polisy Pro connected to Serial PLM all up to date on software. I have replaced the PLM from time to time over the years and as a result have the original DB9 to RJ45 cable that came with the original Serial PLM, plus two brand new never been used serial DB9 to RJ45 cables that came with the new serial PLMs. The weird thing is that neither of the newer serial cables work with the original or new PLM. Only the original cable works. It seems unlikely both new cables would be defective from the factory but I suppose it is possible, unless something has fundamentally changed in how they make the newer cables. Has anyone else experienced this? Quote
elvisimprsntr Posted Thursday at 05:50 AM Posted Thursday at 05:50 AM (edited) Use an ohm meter to compare the pinout of the two sets of DE9 to RJ45 cables. I suspect the new cables are a standard Cisco serial console cable, which is not compatible with the serial PLM, and our mutual friends at the new Insteon don't know or assumed users would know. In which case, you can continue to use the old cables or cut off the RJ45 and re-terminate with the correct pin-out. Edited Thursday at 06:07 AM by elvisimprsntr Quote

Only three wires are used. Serial In; Serial Out; common and in a unique pin out . The other pins are different signals like TTL in and out and the older 2412S also unregulated +12VDC normally around 18.5VDC. To be safe do not connect any other wires to the RJ45 PLM serial connector. Other than the three signals the serial PLM uses. Quote
ErikN Posted Thursday at 12:10 PM Author Posted Thursday at 12:10 PM (edited) Thanks guys. Will give it a try on my next day off. Edited Thursday at 12:10 PM by ErikN Quote
elvisimprsntr Posted Thursday at 12:55 PM Posted Thursday at 12:55 PM For the record page 386 (PDF sheet 399) has the schematic and pin-out. https://cache.insteon.com/developer/developer-guide-022009-en.pdf 2 Quote
