Is the serial cable in the 2413S box. Being used to connect the 2413S to the DB9 adapter?

No it is a serial connection. On a RJ45 jack you normally seen as Ethernet connector. In this case only Pin 7 Common Ground, Pin 1 RS232 (Rx) and Pin 8 RS232 (Tx) are used. To be safe don't let any other signal pins connect to anything. The needed RJ45 to DB9S cable was shipped inside the 2413S shipping cradle but many didn't find it. Pin 1: RS232 to PC pin 2 (Rx) Pin 2: Not Connected Pin 3: TTL Output (from PLM) Pins 4 & 5: Not connected Pin 6: TTL Input (from PLM) Pin 7: Common Ground to PC pin 5 (Ground) Pin 8: RS232 from PC pin 3 (Tx) No Hardware Handshake 19,200 baud 8 data bits No parity 1 stop bit

If they are the older power line only models. 2486D As pointed out power line communications issues. Can cause communications problems. If you can temporally put the module on a electrical cord and try it in a different location. That may show something.

Do you have the PRO add on? Did you double check the IR board is installed correctly and you got the IR support add on to support it?

That sounds correct. Also if it is in a case. Is looks like a PLM. That was the case used for the 2456D. You may want to look at. Since it is power line only. Some changes in the house maybe effecting the communications. Like any new electronic device or existing ones moved. I would suspect the power line interface circuits if both send and receive are a problem. I will see if I have any 2456D modules to look at. I do use the 2456S ApplianceLinc modules.

Which model Lamplinc? Both the original 2456D and dual band 2457D2 where labeled Lamplinc. The 2457D2 later manuals did change the name but the early manuals did call them a Lamplinc.

I would suggest you do some more research on USB and the Polisy port signals. If the port is USB and not TTL but a USB. USB is not TTL signal levels. The adapter can take the TTL levels and make them USB compatible. USB uses a differential levels between D+and D- signal lines. Needs some intelligence to determine things like speed power needed. The PLM TTL signals are at a fixed 19,200 baud rate also not USB compatible. With out a TTL to USB adapter in between the two.

Revision 2.4 and higher. Have the new serial port daughter board in then. With a signal protection network on the serial signals. Also have a serial chip with a better ESD protection specification. A better but not ideal choice. C7 and C13 are now Fujicon TY series caps. Have a better rating for switching supplies. 2.3 has the later serial chip and older serial port board. I also agree with not through a UPS. X10 and now Insteon power line signals. Are frequently absorbed by the UPS power line input conditioning circuits. Having the UPS on a Filterlinc can also stop it from absorbing signals on the power line.

All the capacitors where covered in another extremely long thread here. Some where discontinued and others found. As parts supplies dried up especially during the hight of the pandemic. https://forum.universal-devices.com/topic/13866-repair-of-2413s-plm-when-the-power-supply-fails/

I actually have a revision 1.0. Has (2) 10uF/25VDC caps in it. Along with the rework to add the second capacitor and inductive coil. For a Pi output filter. Original design looks like they originally tried just the one 10uF/25VDC. I have seen many different capacitor sizes used to try for a fix. I also used a well known capacitor brand to fix my 2413S and V2 Access Points using the same main board. V2.4 has the improved serial board in it. With a chip with a better ESD rating and an added network to clamp the signals to a safe level.

02 52 is an X10 signal received message. As you thought. House Code J is a message with all 1 bits on. It maybe possible you have a power line noise maker causing a false receive of all 1 bits. If you have any holiday devices this time of year. You may want to unplug them temporarily. If you moved any exciting electronics you may want to disconnect them and see if anything changed. If some of your modules can have a the set LED flash on receiving a message. That could also give you a clue. Flashing with the noise makers added noise. It is the PLM sending and receiving power line messages. Back and forth to the ISY994i and I would think it would also be what sends and receives messages to a Polisy. Not to much on Insteon RF as that is 915 MHz and the PLM does not receive X10 RF 310MHz. If you have the X10/A10 firmware add on. I believe it assigns a Insteon address to it. When I was using the add on.

I have a few UDI model products with different supply ratings. I have seen 5VDC to 30VDC as the input range. Mine where 5V .5A or 5V 1 Amp. Many here are using 12VDC at 1A or 2A. UDI in their sales page. Last time I looked was a 12VDC 2A. Power LED flashing is probably a defective power supply. I had a few between models all die and where replaced. Especially if yours is still the original.

Thanks for the information. Does not sound real encouraging. I had six of them and all the plastic back are cracked and will possibly fall off when trying to unplug them.

The Fujucon TY sheet I have. Says 2000 to 7000 Hr load life at 105C. Still not the most reputable cap in my opinion. Your finding other bad components. Would explain why some still had problems after a capacitor replacement. While others started working again.

Yes UDI did have a prototype PLM and then Smartlabs reneged on the promised programed controller chips. Thus killing the product completely. There where a few other manufacturers on a list we got in the developers group. To start Insteon support. They changed their minds and went other routes like ZWave. Smartlabs was always protective of their Insteon products. Too soon to comment on the new Insteon Group.

Hardware revision 2.3 changed the caps to a Fujicon TY type and is designed for switching supplies and what looks like a slightly better time rating. A MAX232EI serial port chip. With better ESD ratings. Though sticking with Fujicon may not be the best choice. Revision 2.4 and above. Also has a new serial port daughter board. That also has a signal protection network on the two serial signals to and from the PLM. I actually have a V1.0 with 10uF/25V caps for C7 and C13 and reworked to add the Pi filter components. That they look like they didn't put into the original design. I have seen many different caps for C7 and C13. As they unsuccessfully tried to fix the power supply issues. I too have seen network jack connections issues reported.

If it was a power supply capacitor issue. I would think replacing them would help. If is the serial port chip then it may not help. At V2.3 they changed the chip to one with better ESD ratings and V2.4 and up has a new serial daughter board with the better chip and some signal protection on them. If you are having many PLM's giving the -10. You may want to verify the cable between the PLM and the ISY controller is 100% OK.

Both 2413U and 2431S where on the expected release dates data they posted. March of 2023. If the list is up to date.

Your diagram does not look correct. P2 on the diagram. Back side where pins are inserted. Pin 1 Top Left pin position. Pin 5 on the Top Right. Blue to P2 Pin 2, Brown P2 Pin 5, White to P2 Pin 3. Top left to top right: 1 NC, 2 Blue, 3 White, 4 NC, 5 Brown. Bottom row 6-9 all NC. All the rest of the wires from the network side. Should be insulated from each other and not connected to anything. As two of them are not used TTL versions of send and received signals.

None of my 2476S SwitchLinc module have all the LED positions installed. Only the On and Off LED are there. So even if it could be used to control a dimmer. There are no LED positions to show where the switch set another module, just empty holes with the light pipe in it. The FCC Database photos of the 2477S modules. Also only show the On and Off LED installed. So if anyone has all LED's in a switch module. It must have only been in certain revisions. The old company did indicate you could buy a cover with all the positions so they matched the one you where using now.

List indicated new 2413S PLM near the end of the first quarter of 2023. Improved specification one in second quarter of 2023.

The company went belly up in the early 2022 and everything was gone. Including the HUB servers. The company has opened under new management. Many are employees from the older management. Yes they are again selling modules and have posted a list of dates when things should again be in stock for sale again. The 2477D was one of the modules being sold again. They have resumed production of modules. Things like new 2413S PLM scheduled for the first quarter of 2023 and the improved PLM in the second quarter.

If it is functioning OK except the normally very bright Power LED. The LED maybe failing or the current limiting resistor maybe failing. As it is directly driven by the ISY internal power supply. If it starts also having dimmer indicator LED brightness or it starts to malfunction. I would suspect more than a Power LED circuit issue. Power supply range is 5VDC to 30VDC. Most find a 12VDC works fine. Note the ISY store now sells 12VDC 2 Amp replacements. Not too clear on the ISY994 being stocked again. As the eisy unit is in the near future and there is Z-Wave available also. I do remember a few other posts here. Where the users ISY99i was working fine but the power LED was Off. Didn't see any information on it effecting anything or a fix.

That is very good news. Thank you for finding it out and posting it for all to read.
