The serial speed of a 2413S is 19,200 Baud, No Parity, 8 Bits and 1 Stop Bit. I too have seen reports of longer distances. With good quality cable.

Memory here. I believe for a time they had 5.5mm barrel and 2.5mm pin. All of mine are the 5.5mm barrel and 2.1mm pin. If you took one from another ISY994i and it was one of the ones with the 2.5mm pin. Using it on a 2.1mm pin would be sloppy and maybe exhibit what you are experiencing.

There was a time period where the connector was a different pin size. They do make an adapter. 2.5mm to 2.1mm and a 2.1 to 2.5mm pin. Depending om which way you have to go. If it is loose My thoughts are the supply has a 2.5mm center pin socket and the ISY994i has a 2.1MM pin.

The ISY994i has a wide range of voltages it can accept, 5 to 30 volts.. My ISY99i was 5V .5A. I have two ISY994i. One was 5 volts .5A and the other was 5V 1A. UDI sells a replacement it is 12 V 1A last time I looked. Others have also had there supplies go bad. Two of mine did.

Glad you had no issues. Others have until a Factory Reset was done.

This is the start of adding a 2856D2 V4.3 ID# 16.81.F0 The line showing the module responded back. [ INST-SRX ] Is what I don't see in your LOG.

The module is not responding back to the ISY994i. As there are no received message back showing in the log. Double check you have the right six digit Insteon ID when you are trying to add it. Some digits are easy to read incorrectly. Like 0 and D are one we see. The 2456D is the older power line only type module. You may want to try adding it on a different outlet or maybe even the same branch circuit as the PLM. If it works there. You may have a signal coupling issue if it is on the other phase of the incoming power or power line noise, signal sucker issue. Do you have any Dual Band modules to couple the two phases?

Are you putting the +5 volts DC into the Sensor Input? It has its own internal 5 volt sensing supply signal and is designed to have a dry contact on the sensor input. Though 5 volts probably would not damage it The retail #2822-222 is a 2450 I/OLinc. Sold by retail vendors. Though you may not have much luck finding them either.

It has been reported. You can take the serial board out of the old 2413S and put it into the 2413U. Converting it from USB to Serial.

This page from the UDI WIKI may start to give you some information. https://wiki.universal-devices.com/index.php?title=ISY-99i/ISY-26_INSTEON:Errors_And_Error_Messages

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.

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/

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.
