The 2414U and 2414S are the old PowerLinc V2 PC controller. It is a completely different interface. That had memory we could download assembled programs to and run alone. Also had a real Time Clock in it. Different communications protocol than a 2412S/U or 2413S/U PLM. I can't say for sure but it probably is not supported.

That is the way I see it. UDI did develop its own version of the PLM. With a promise from Smatlabs to provide the needed programmed controller chips. Then after developing it Smartlabs backed out. Leaving UID high and dry. So they will not allow it to be made.

If you had the system powered down for a few hours. Then powered it back up and it saw the PLM. Even for a brief time. That is one of the typical failing PLM power supply issues. Others have swapped the serial card from the old PLM to the 2413U PLM and it worked fine. Though there is always a slim chance the serial port board has an issue. At V2.3 they used a serial interface chip with better ESD protection. V2.4 they redesigned the serial board and added signal protection to the serial signals.

Others here have purchased a 2413U and swapped the Serial Daughter board from the old one. With success. The RJ45 style connector on a 2413S looks like a network connection but is really a Serial Port connection. Both the ISY994i and 2413S have serial signals on the network style cable between them. A HUB is not compatible with an ISY994i.

You can use the built in communications test [4 tap test] to check communications. Depending on a V1 with white LED or V2 with a red/green LED. You will get a LED flash pattern to indicate communicating and on same or opposite phase. The users manual gives the flash patterns for both versions and how a mixture of versions flash. 2443V2.pdf

The 2443 Access Points where discontinued and the presently sold 2992-222 Range Extender is now what is used for communications coupling. If needed since Dual Band Devices have made the need for them mostly unneeded. It is a 2475D2 Lamplinc with the dimmer parts removed. Most used a full Dual Band device as they also could be used for load control.

If you had a later revision. With the larger capacity and voltage ratings C7 and C13. You will find that they mounted the capacitors laying side ways parallel to the board. With the leads bent to fit into the original mounting solder holes in the board.

If the 2443 Access Points are a Hardware Revision 2.0 or higher. They are built on the same base 2413 PLM main board and suffer the same capacitor issues as the 2413s PLM. I had a pair of mine fail and I rebuilt them from the long PLM repair thread here.

And revision 1.B is one of them with the older choice of caps. Hope the seller guarantees it is a working module or has a return policy.

The rev 1 has the older power transformer main board and a RF board. Much heavier as you have seen. None of my rev 2 have a daughter board in them. Since they have the 2413 main board in then with built in RF features. The old 2442 SignalincRF units. Had the same power transformer main board but a different RF daughter board and an external antenna rod. Smarthome converted a few of my 2442 models to 2443 models. By exchanging the RF board to one found in a rev 1 2443. Probably a firmware change also.

Metal electrical boxes. Can also effect Insteon RF communications. All the Dual Band switches I saw in the FCC database. Have their antenna on the rear side of the module. Deepest into the electrical box. Though Dual Bands power line commands can add reliability. RF only devices don't have.

There have been reports here. That using a 2413S Serial Port daughter board in a 2413U. Worked well for them. The 2413U and 2413S use the same main board. Only the daughter boards are different. If you do a command Get IM Info. That reports the PLMs information. A 2413U with a 2413S daughter board. Will report its Category and Subcategory as a 2413U not a 2413S. Unless a device using it wants to know what it is using. Most likely would not mater. Since they both used the same main board. Both the 2413U and 2413S have the exact same capacitors in them. Later hardware revisions have some capacitors in them designed for switching power supplies. The revision 2. 2443 Access Points also have the same base 2413 main board in them. I had a pair of them also go bad.

I thought they had the universal power supplies. So both 120 and 230 volts 50 60 Cycles would work. Only thing I could see different would be the RF frequency matching the local countries standards.

What is the hardware revision on the 213U/

Are you asking about their EZIComm PLM or the Insteon 2412S or 2413S? The EZIO8SA would work with all of them. Mine are a 2412S with the EZIO8SA. The EZIComm was an Insteon base PLM with their own daughter board. It was originally a 2412 base board. Then a 2413 base board. Has issues like we did with the 2413 so they went back to the 2412 base board. I don't see why it would not work in any posts I have seen, but I don't know for a fact. Can it be used for parts. Depends on if it is a 2412 or 2413 base board and if they did any tweaking of the base boards firmware if any.

Is the PLM a 2412S or the presently used 2413S? The 2412S was power line only and could power the ISY controller. Through the serial port cable. The 2413S does not so the external ISY power supply is needed. I have seen some buying a 2413U USB PLM and then swapping the serial board from the old serial PLM into the new PLM. I have not seen any reports of a HUB and an ISY controller working with each other. The earlier version HUB also had power supply issues. So use care if you find one. As there where two models. 2242-222 and 2245-222.

I believe the swap was from a 2413S serial board into a 2413U PLM. The 2413S serial board has a faster speed link database memory chip. Not sure how a 2412U main board would mix with a 2413S serial board. Possible memory access issues. If the 2412U was an early version hardware. It may have firmware in it for the original 417 link data base used in the early versions. I did put a 2413S serial board into a 2412U PLM. I did not do any testing of this. Other than using a few PLM test programs to see it it even worked. It did work with the tests but not a test with an ISY994i.

If the 4 test does not work. There are a few modules that you have to look at the manual for it. Then perform the Beacon Test. Through a series of set button pushes and LED color and flash patterns. To start it. It is in a flow chart in the modules manual.

Smart Meter communications. May possibly be it but I have only seen one brand meters communications protocol. Cause the issue. A majority of them. Where not reported as the causing issues. Any X10 RF remotes and transceivers in the home?

9E is the firmware in the PLM. It has been in a few hardware revisions now. On the back of the PLM should be a hardware revision label. Along with the Date Code and 6 digit Insteon ID number. The revision number maybe a help. You may want to go into Tools, Diagnostics, Show PLM Link Table. To see if the links are there and about how many of them there are.

On the two wire X10 dimmer wall switches. The slider switch disconnects the line power into the switch. So you can safely change a burned out bulb. As they get power through the load. Do you have any X10 repeater between the two incoming power lines? They have been known to see the end of an Insteon message as a bogus X10 message and resend it. If you have one. I would try disconnecting it as a test. J Status Request is all data bits in an X10 message as a 1. X10 message 11111111. It maybe noise as you thought. You may want to go around and start disconnecting things. Like phone and other rechargeable device chargers. Electronic devices. Computing equipment, sound equipment and see if anything changes. In the Event Viewer in Level 3. You maybe able to see the changes as you test with disconnecting things. Do you have a Smart Electric Meter? I did see one communications protocol reported the cause X10 issues.

Thank you for the information. Good idea on the Modem Availability Alerts thread,

The 2448A7 is Insteon RF only. So you need a Dual Band module to pass the information between it and the rest of the system. It also does not do X10 at all. The 2413U should do X10 power line commands.

You may want to run the Event Viewer in Level 3. To see if the messages show anything. Since the I/OLinc is power line only. You may want to try in a different location and branch circuit as a test.

What firmware in the unit and does the UI match the firmware version. Have you tried the ISY Launcher as it is the recommended way to access the ISY unit.
