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

That sounds right. See page #6 2440new.pdf

Thanks for the information on the RJ45 RS232 use. As long as someone doesn't think it is a network connection and try that route. 😀 The Serial RJ45 pin out is not even close to what Smarthome did with their custom signal connections. Like TTL and +12VDC on some of the pins. Using an adapter. Where the user can select what wire goes to what pin. Should work.

Swapping the USB daughter board with the Serial Port daughter should work. As long as the attached interface does not check the PLM ID that is attached. As the 2413U with serial board will identify with the Category and Subcategory ID of a 2413U. The ISY994i does check for a connected PLM and shows its firmware but don't it checks the USB or Serial status. I put a serial board in a 2412U and did a few test software tries. It did seem to work just fine. It did ID as a USB version. A serial board from a 2412S I would be cautious of. As the 2412S had a slower link database memory speed and early ones where 417 links. Houselinc checks for the module it is interfacing with. So it may or may not be 100%. As I remember they came out with an updated file to include the newer versions of the 2413S and 2413U with a later Subcategory number.

Insteon devices only support X10 power line commands and do not repeat X10 commands on the power line or by RF signals. Dual band Insteon modules also do not receive the X10 RF 310 MHz only the Insteon 915 MHz. Some of the later Insteon modules dropped the Primary X10 address feature and did not support X10 at all.

What are you trying to do? Does the Eisy have a serial RJ45 network style connector. That Smathomes unique serial format connector used and not the standard DB9S for serial communications? I would seriously doubt it. So best thoughts no. The three wire connections from the RJ45 unique serial connector to the DB9S. Is documented in a few places and in this thread.

The text you posted. Looks like it still was using I2 communications.

When first powered up. The manual indicates it goes into a calibration routine. Not too sure if that has any early linking attempts. Mine is in the box unused but did a test with it. Good point on the power line only communications. My V1.1 firmware V.30 in the expanded Event Viewer also shows " Not sure if it is an I2 device" so it reverted to I1. That is a lot of peeks and pokes on the power lines. So close to the PLM may help. This was in a test with 5.0.16C in the ISY994i Your V1.15 test in your original post shows it doesn't have any links in it.

Smarthome used the unique serial signal interface connector way back to the X10 days. Seems when they use something they stick to the same misunderstood connector. Many where confused. The RJ45 connector on the 2413S, 2412S PLM and Port A on the ISY994i are Serial Signals not the normally thought of Ethernet use. The PLM also has a set of TTL level signal pins that should not be connected to anything in this application. 2412S also had a unregulated +12VDC around +18VDC. That should also not be connected to anything in this application. This information is on the sheet provided in the box along with the needed cable serial cable with only three wires needed for serial communications. In the cradle holding the PLM and with unfortunately, no label to give the user any clue it was there. Sometimes resulting in it being discarded.

I think some users using a network adapter. May have gotten the send and receive signals reversed or incorrectly wired. Accidentally connected the TTL signals to something. If using a 2412S RJ45 Pin2 is unregulated +12VDC, around +18V in my tests. The quick sheet with the PLM had in my opinion easily to make an error.

There where two link database sized 2412S. Early revisions where 417 Links, later where 2016 links. The 2016 link models where reported to start missing things at around 800 links. Slower memory as reported over the 1023 link 2413S link memory. The serial daughter board in the V2.3 2313S and below is the same board but as you indicated a slower memory speed. 2.4 and above the serial chip had a higher ESD rating and the signal line protective network on them.

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.
