2413U / 2413S question

[randysachs]

This might have been covered before but I didn't see anything with a quick search.

Has anyone tried, or is it even possible, to take a 2413U and swap out its communication board from one in a 2413S and use it as a serial modem? I'm just curious since the 2413S is always unavailable but it seems like the 2413U is still around. From what I've seen on the net the only real difference seems to be the comm board, and the S failures mostly seem to be in the main board's power supply caps failing.

I'm not that desperate yet, I still have a spare S and a couple of dead 2413S units I'll probably recap to see if they come back to life. But if a swap was a viable solution it might help some folks who have dead 2413S's since anyone could do a board swap in a matter of minutes.

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 have a few older 2443's laying around so just took a look inside. I suspected they would be quite different just because they weigh a lot more than any other Insteon device I've see. Those are quite different inside with a fairly large 12V AC transformer inside instead of a switching power supply. Both the Rev 1 & 2 have the same main board with very different RF boards in them.

They do have the same header setup in them as the 2413, it might be interesting to try a swap but first I'd have to at least check all the pin voltages to make sure they wouldn't kill the comm board.

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.

I ordered a bunch of caps from Mouser and I'll try the repair on my dead ones next week. I'm also thinking I'll punch some ventilation holes in the case to let them breathe a little if they come back to life. Can't hurt.

I just saw a used 2413S V1.B sell on eBay for $305 with over 30 bids. Folks are getting desperate out there.

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.

There's going to be a few more pretty soon

Can you scan your order invoice and post it here.  Of course redact your personal info. 

Just would like a current, updated list of all the components. 

I've been living with my intermittent PLM for about 4 months, since the last power outage.

Thanks in advance

I'll be happy to once I get the parts and make sure they'll all fit. I had to do some substitutions due to the supply chain issues and it's a bit of a crap shoot at this point.

There's a guy selling a ready made package on ebay. It's a little more expensive than getting them from Mouser but still less than 20 bucks. If you want to get it done quickly you might want to take that route.

Alrighty then. Got the parts today and the PLM is up and running nicely. I did the V1.B for starters, but assume the V1.6 should go as well. I tested it with Linknet 2020, resetting it to default then adding one Lamplinc 2457D2 as a test unit. I had no problem controlling it from across the house so it's a win.

I've attached the parts list from Mouser. The only thing that was at all dicey were the two 10uF / 50V ones, they were a bit physically wider than the original 35V ones and one was a tight fit next to another cap on the board. The 400 volt one is much taller than stock but fit fine  Other than that it was smooth sailing though at the advanced age of 64 the old eyes just ain't what they used to be for doing PCB work. ?

Here's the original list I was working from:

Replace YICCON 6.8uF 250V cap with      ESX106M400AH4AA 10uF 400 volt
Replace FUJICON 100uF 25V cap with     UTT1E101MPD 100uF 25 volt
Replace SAMCON 10uF 35v cap with        EKY-500ETD100ME11D 10uF 50 Volt (2 of these)
Replace FUJICON 10uF 16V cap with        UTS1C100MDD 10uF 16 volt 

Now I'm debating if I should sell the repaired one on eBay since I'll still have two backups. After seeing a V1.B go for 300 bucks last week it's very tempting...

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.
