The 2450 I/OLink has the same switching power supply IC as the 2413 PLM. I have an older one with small caps and a few later ones where Smartlabs tried a bigger cap but it still was not rated for a switching supply. Can not say about the very latest ones. The surge suppressor warning maybe some have noise suppression components. The 2450 is power line only and that type of unit would suck up the Insteon Power Line Commands. Greatly reducing the distance it could receive commands.

Thank you for the information. It should be a help to some users of the RA2 products.

The eisy is a brand new product. That you seem to want to call your discontinued ISY994i. If you have a ISY994i. Look at the two LED's on the port 'A' connector and note their actions. That may give you a clue to what is happening.

If you have the 2477S Relay model. The new one may have a face plate with only the Off and On LED positions. The rest of the plate does not have any unused LED positions. Can't say if the new company went back to all positions on the face plat. The old ones will fit as the old company said the old ones fit fine. If you wanted all of them to have the same LED pattern as you older installed ones.

They are in a power saving mode and will not receive updates. Until you wake one up and then restore it. You may have a option (PRO firmware in an ISY994i) to disable automatic writes the wireless devices and then do each one individuality.

Thank you for the findings. Maybe possible with the button routines. I forgot the Set Button Programming sequences. It does look like the LED brightness can be adjusted. I had looked in the Software Only section and it did not look like it could be adjusted remotely just with some manual button clicks and led indications.

I have a Light Dim on my ISY994i. Power LED to dim it out. I did not see the LED settings mentioned in any of the 2475D manuals I have in my archives.

The switch with the Red capped off. Is linked to another switch. That is controlling the load. When you replaced the bad one. Did you verify it was linked to the one with the load connected? Since the 2476D is the older power line only and the 2477D is dual band. You may have to do some manual things to get the new ones completely installed.

Verify the POE source voltage. The eisy is strictly 12V DC from what I saw on its sales page.

UDI sells a Serial to USB adapter. To use a 2413S on a Polisy. https://www.universal-devices.com/product/serial-plm-kit/ Don't have any information on the units serial port and if it is live. I think your pin out may need checking. From the sheet in the 2413S box. RJ45 Pin 1 to DB9S PC pin 2, RJ45 Pin 7 to DB9S Pin 5 and RJ45 Pin 8 to DB9S Pin 3

It can be confusing to some users. Yes it is a serial connection but on a RJ45 network cable and connector. Used for serial communications.

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.

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.

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.

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.

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.
