I have seen other brand resistors also used. Designed for a two wire switch. With success.

The ISY994i discontinued indicates you can purchase modules until 06/01/2022. So I would second contacting UDI. As the procedure was changed awhile back. I purchased some for my back up ISY994i a few weeks back. https://www.universal-devices.com/byebye994/

Best to use only the three needed wires. As there are other signals on the PLM RJ45 jack that can possible connected to other things and effect the operation. Like the unused TTL level In and out signals. Insulate and don't connect to anything.

The PLM only uses three wires and the pin out is unique. So you have to use the correct three wires in the DB9 to RJ45 serial adapter for the connections.

The two outlined areas of the 2413 main board. Are programming connectors used by the vendor to program the main board controllers. One RF controller and the other one is the main controller. They have +5 VDC and Common Ground. Along with some other needed signals for programming. The main power supply is unregulated +12VDC that runs around +18VDC. Regulators on the main board and daughter board for logic supply. On the daughter board pin 1 and 8 are the unregulated +12VDC The developers guides where for the old power line only 2412. With a power transformer style power supply and not the switching supply in a 2413. I have seen a schematic here for the switcher and will try and find it. The guides should show you the two pins on the connector. If you have serial port on the computer. BusyRats test program may work but it requires you to send and receive the hex commands seen in the guides. The developers group also gave us a script to use with the free evaluation version of DockLight Scripting. Depending on what version developer kit we had determined what it did. I modified on one the scripts with a plain text editor for my use. As saving changes are not in the evaluation free version. Did basic things like dump the link database and turn on some of my old X10 modules. Also used a serial port but commands I used didn't need the hex data.

2413S and 2413U are both the same performance wise. Different interface to the outside world. 2413U has the USB interface inside the PLM. 2412S and 2412U are the older power line only ones and have slower link memory. The new PLM in the FCC Database will probably be later this year if at all.

I too have seen supplies look fine with a meter no load and have almost no output when loaded. One of mine on an ISY controller was that way. Though none of mine had a Blue LED.

It is definitely different. Near the bottom of the Quick Start Guide. On the given link. It has the Nokia option to be set to either a dimmer or a On Off device with some set button sequences. It was posted that the Nokia modules where not 100% feature wise from a standard Insteon Module. Good to see it was even seen at all in the ISY controller.

The screen shot shows it is an Unsupported Device. Probably had to be added with Start Linking mode as auto probably will not find it. Not clear right now. How much the new device was programed after originally being a Nokia Module. I would imagine at least. It may have the same Category and new Subcategory when interrogate for an ID.

Than you for the log data. I am sure it will be of a big help.

You may want to look at this wiki page. https://wiki.universal-devices.com/index.php?title=ISY-994i_Series:Migrating_To_Your_ISY-994i The finder will not work on that model. As even the latest ISY99i firmware is too old for it to find and run it. The 2412S can power the ISY994i. So the use the original PLM may power the ISY994i over the serial line. Not clear if you use the ISY994i and the replacement PLM.

I did not see it on the eisy pages of the UDI sales pages or lilyoyo1's link here. Another point. The 2412UH was the model with a different Subcategory that the proprietary version of HouseLinc checked before allowing it to work. It has a slower clock speed over the 2413S/U and may even have the smaller link database found in the earlier revisions.

We have seen our share of power supply issues and the ISY994i. I had a weak one and the ISY994i was working sort of. I did a power cycle reset and it never came back up. All the LED's just pulsed on and off. If you looked at the output an did not have a load on it. It could still read OK until loaded.

There where two major hardware 2456S3 modules along with different firmware. The V1.3 and all the other V1.?. Have a 120VAC relay in it along with its hardware. The V4.0 and above. Where completely redesigned with a 24VDC relay and hardware. V1.? modules had local control sensing. Enabled and you had to disable it with an added X10 Off address. The V4.? have local control sensing disabled and you used a some set button routines to enable it.

Just got an email from UDI. There is a 20% discount on PLM repairs through the new Insteon site. With a discount code in the information page of Insteon.com

From the official notice on the ISY-994i a few weeks ago. Indicated it was produced for sixteen years. How long would you want a device to be made and supported? I have not seen many manufactures still have no cost customer serve for more than a year or too on a purchased device. I have seen UDI bend over backwards to assist someone.

For the 2412S or 2413S. The PLM serial connector is a network style RJ45 with serial signals on it. As linked to in the previous reply. There was a cable with the needed RJ45 to DB9S inside the boxes shipping material. Material not marked so many missed it or tossed it with the empty box. There are some custom cables construction posts here also.

Hopefully the new management. Will give the whole 2413S/U a good look at. Parts wise. Over the previous owners band aid tries to fix it. With different sized capacitors all of dubious quality.

Since the ISY994i has been officially discontinued and support time is now limited. Not to sure what you may get done. https://www.universal-devices.com/byebye994/ https://wiki.universal-devices.com/index.php?title=Main_Page#ISY_Portal:_Integration_with_Amazon_Echo/Google_Home/IFTTT https://www.universal-devices.com/ https://wiki.universal-devices.com/index.php?title=Main_Page

I have seen a module. You could wire in parallel with the load. That sometimes helped with flicker. Don't have any data easily found right now. I agree some bulbs electronics are just don't play well with Insteon power line signals. While others do.

The UPS power filtering can absorb the power line commands from a PLM. Many also don't have a true sine wave AC output. That many power supplies don't run with. No UPS on a PLM is a very good recommendation. FilterLinc sound like a good way to go. That is how mine is. PLM in the unfiltered outlet on the front. Computer equipment on the filtered outlet.

You may also want to note the firmware version of the modules. Reported in the Administrative Console. As date code and hardware version. Doesn't always indicate a firmware version. As some modules like the 2413S PLM have the same firmware in more than one revision. I have see 9E in more than one and I maybe the same one still being used.

Glad you found the problem device causing power line issues.

The sales page. Does indicate you need the RJ45 Serial type port to a USB signal. Is plainly called out on the Eisy page. The adapter is not overly costly, but would add some cost to those with the 2413U and 2412U PLM. As it has to have a Serial to USB converter and has to have the custom RJ45 serial port signals on it. That the more commonly network serial cables do not match what Smarthome decided to use.

Just looked at the kit. So you are using the network style cable, RJ45 to DB9 adapter, and the USB adapter in the kit? Unless the kit has been changed. I don't think you need any cables you made. I saw a mention of the improved PLM being Q2 and the 2413S March of 2023
