CableWholesale 31D1-16410 Modular Adapter, Gray, DB9 Female to RJ12 Jack

Used this product to link a Power Line Modem to a Universal Devices Polisy. Converting the serial device from a previous connection made by use of an IP cable since the Polisy has a 9-Pin serial connector and the PLM has an RJ45 connector. I had something to follow from Universal Devices, but I checked it against the data sheet for the product to ensure it was correct. Works well. Do know, if you push a connector into one of the Serial plug sockets, you cannot take it back out.

I read a couple of negative reviews complaining that the pins could not be removed once inserted.Of course not else when you attached a male db9 to this female it would force the pins out of the housing.If you inadvertently insert a pin into the wrong hole you need to use a pin extractor designed for this type of pin such as the AMP 91285 pictured. The tool is inserted from the rear. In a pinch you could probably make something, it's just a narrow steel tube with a slit down the length to allow the wire to enter

Simple design that can be adapted easily to whatever pinout is needed. In my case, I used it to connect an Insteon serial powerline modem (PLM) to a Universal Devices eisy smart home controller. An additional cable was needed to go from this headshell to USB, but docs are available online on what to get there. This headshell took a couple of minutes to configure and works like a charm.

I wish serial devices would stick to a few basic pinouts, but they do not. You can make any reasonable combination that you want with this without too much fuss.

[Something Most Sane People will Never Need.]As for the rest of use, condolences.It's ok.Worked for me.Be advised;There is no pinout information on the bag, in the bag, on the shell, etc.No big deal.Just ring out the leads with a continuity meter.You have no continuity meter - you say.Then use the Force.One can peer into the back shell with a flash light - and, make a semi-educated guess.Once I had the pinout established, I was faced with deciding which colored wire should go in to which hole.Sounds simple enough.Should have been simple enough.The schematic drawing I had to go by was logically impossible to comply with.Once again, Use the Force - Luke.The bag should have included a socket extraction tool.Fortunately, I had one.Three attempts later - and, I still had issues.By not following the manufacturer's instructions.And, by following established RS232 conventions, I managed to get it to work.Summary:It is quite useful.If you get it right the first time, you won't need an extraction tool.I'd recommend it.Expect to put in more time and effort than expected.
