Is the standard USB cable. With the A and B connectors.

Jeff at JV Digital also has a great set of tutorials on things like noise. On X10 issues and many apply to Insteon Noise also. https://jvde.us/x10-troubleshooting/

Both of the firmware revisions are in the old 2412S power line only PLM. Comparison to a presently sold and completely different electronics 2413S firmware 9E. May not be a good comparison.

I would also be very interested in the information.

The Developers Guide may also give you some data. Is sort of dated by now but still has good information in it. http://cache.insteon.com/developer/developer-guide-022009-en.pdf

IndyMike covered things. I would second if you have older power line modules and the system is resorted to I1 communications. That takes eight message and acknowledgement for one link database replacement in a module. Noise and communication issues may effect the restore or PLM replacement messages.

Is the 2.6 on the white sticker of the PLM? That is the revision level 2.6 not the firmware. The probably version firmware is 9E. As I know rev 2.5 had the 9E and I don't think they went higher as 9E had been the standard over many revisions. Revision 2.4 and 2.5 have the new serial port board and power supply capacitors. So you should have the better PLM as the replacement.

If you are not in the 4Tap-Beacon-Communications test and your module has the blink LED on traffic and it is enabled. Noise can flash the LED. I have also seen some mention that noise can occasionally fool the polite feature in a module and it waits to send until it thinks it is clear.

The supply in the link. Is 12V 1Amp the converter for the other sized barrel connector adapter is .6A

UPS units have a power line conditioner in them. That see Insteon and X10 power line signals as noise and absorb the signals. So another possibility is the UPS is absorbing the signals. Fix is the same a FilterLinc on the UPS AC input. I have a FilterLinc on my UPS and the 2413S PLM on the unfiltered outlet on the front.

Are the effected ones new enough to be Dual Band? The original power line only modules will not respond to a 4 tap or communications test. I too think you may have a new noise source or signal sucker. If only a few or many do not follow commands.

We can't update the firmware. Technically the folks at Insteon could. The PLM has two programming connectors. One for the RF controller and the other main controller. Though you need a programmer used for the model controller chip being used and the Source Code and we know that will probably never be made public.

Here is one I found. It is a common issue with the I/OLinc as it was not updated (as far as I know) to remove the All On response. https://forum.universal-devices.com/topic/42728-garage-door-opens-unexpectedly/page/2/#comment-379116

I have had similar findings with an ISY99i and ISY994i. Bad power supply and flashing power on led.

eiay or a ISY994i? If an ISY994i do you have the PRO model?

I am also using a V572. In my case I used the TW523 port on my XTB-IIR. Jeff's great XTB523 is also well known and works great. Unfortunately WGL has also gone out of business.

Yes like all RF only devices. You have to wake it up first. If you picked with the link management remotelinc2 method. I believe it gives you the method as you try and add it. I believe using the SET button to start it in the linking mode. Full Manual should have given you that. If you had the PRO option. On the top of the administrative console. Would be two added choices. For Automatic updates for RF devices and for Automatic updates for all devises. It also allowed a larger number of devices you could use with the ISY994i. If it didn't come with PRO. You would have to purchase it to add it.

Are you using the Link a Remotelinc2 choice in the Link Management list? That should give you three choices. 8 Scene, 2 Scene and Switch. In your case 8 scene. From the product information we got in the Developers Group. 0 1A 8 Scene US frequency. 0 1B 4 Scene US frequency. 0 1C On Off switch US frequency. The other numbers you are seeing. Are for the older 2443A2xxx remotes and not what you indicated you have. Remember if you have the PRO add on. Make sure you have automatic updates to RF devices enabled. https://cache.insteon.com/documentation/2342-x22-en.pdf

Good to see you found the problem and a way to correct it. Also shows the new PLM also still will receive X10. Coming from an X10 start. Power line noise, phase coupling and signal suckers. Was a common issue for us.

The passive X10 SignaLinc device. That is hard wired between the two Lines? I have seen posts where the capacitor has failed and the coupler is not working. In the 2406H. https://forum.universal-devices.com/topic/28722-anyone-dissect-a-2406h-phase-coupler/ . The X10 4816H used a 18uH coil and a .1uF capacitor. As there where two. 4816H was the X10 and 2406H was the Insteon X10 signals are close enough to the Insteon signals. Both would usually work fine. You can still find the X10 4816H on sites like Ebay. If IndyMike thinks it would help your X10 issue.

That sounds like the way my 2450 acts when in Momentary Mode. When I did some tests.

9E has been the standard firmware from back at least to V2.1. Hardware changes did happen. Like changing C7 and C13 to one made for switching power supplies. Serial chip on the serial daughter board to one with a better ESD rating. Now a redesigned serial daughter board. With some added surge protection on the two serial signals. My ISY994I with 9E in the PLM. No problem with sending or receiving X10 and showing in the Event Viewer.

If they changed the X10 commands in firmware. It should have caused a new firmware version number. I don't use an eisy. In an ISY994i. It can be found in the Administrative Console, Diagnostics, PLM Info/Status. Should give you the six digit Insteon ID number, firmware revision (mine is 9E), connected if being used by the controller. I seriously doubt they removed the received X10 message from the PLM to the controller and left the transmit X10 message from the controller to the PLM. If you use the Insteon Forums. You could also ask there. https://forum.insteon.com/forum. Or there own support address https://www.insteon.com/support Over the years. I have seen occasionally an X10 received problem with the PLM. Most times it was the hardware in the PLM having issues.

Thank you for the updates on the All On commands. Still being in some modules. I saw your posts on the Insteon Forums. Lets hope they will correct the removal of that command. I suspect some information was carried over from the old management and just make more with the same firmware.

Your new PLM is a 2413U or a 2413S with their USB to serial adapter? Wired with the special pin outs for the 2413S? Do you have a screen that gives you the firmware version in the PLM by chance? Did you have the optional A10/X10 module add on in the ISY994i? I don't have an eisy but have seen it used the USB interface and didn't use a serial port directly. I don't think Insteon changed anything in the latest 2413 PLM to remove X10 reception.
