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.

There is a way to test the PLM independently but it is not totally easy thing to do. You need the Insteon Serial Port cable in the PLM box. Maybe in the folds of the cradle holding the PLM in the box. A serial port on the computer. BusyRats PLM test program or Docklight Scripting program. You can get and run it in the demo mode. DockLight Scripting was what they had us uses. When the Insteon Developers Group was active. Docklight Scripting is the easier on the use. As I have a modified test program you can use and then pick tests from a menu. Sends it basic commands and you should get a response back if it is working. Are the RX and TX LEDs on the ISY994i flashing. When you try and access the PLM?

During boot up. The ISY994i checks to see if a PLM is connected and responding. So a powered up PLM first before the iSY994i. Is the suggested way to go.

The ApplianceLinc has been gone for a long time as you noted. Was me in my way back machine again. Showing that Smarthome liked to reuse their module names.

The SwitchLinc name was used on the X10 compatible and early Insteon modules. With Insteon it was SwitchLinc V2. When you could get both X10 and Insteon modules from Smarthome. Eventually the X10 line want away and only the Insteon modules. Where being sold and the name changed. Same for the ApplianceLinc modules. When both X10 and Insteon types where being sold. The Insteon ones where ApplianceLinc V2.

You may want to do a show device link table test and then a compare to see if the devices link table matches what the ISY interface knows should be there. I have not tried this myself. A member here bought a new 2413U USB PLM and then took the serial port board out of the old one and installed it into the 2413U. Then used it on their ISY interface fine. That would work as long as the old PLM didn't have a serial port board issue also.

Your memory is good. The maximum was dropped from 9 minutes to 8 minutes. Trying to set 9 minutes goes back to around 2 seconds. I don't think there is a secret way to get 9 minutes on the updated modules ramp rates.

63 Links sound low for most setups. You may what to try it a few times. As any activity may cause the count to be incorrect. Did you power cycle the PLM? Two of the signs the PLM has power supply issues. Is a low link count and works for awhile after a power cycle. Though a 2020 purchase sounds like a awfully short time span. Can you see the Date Code and Hardware Versions on the back side of the PLM. That may also give you a clue.

Depending on the hardware revision you are trying to rebuild. You may find a different size capacitor in the C7 and C13 positions. The kit has the latest 100uF/50V capacitors in it. In mine they are too large physically to fit into the locations on the main board. So they are parallel to the board and the two leads are bent 90 degrees into the solder pads. If you choose to get the 7 capacitor kit. Check the revision sticker on the rear of the case. Hardware V2.4 and above. Has a new serial board and no C2 or C5. The older serial board has a C2 and 4 small capacitors 1uF/25V that I have see anyone try and change. As far as I can tell. C5 is only in the Smartenit EZIO relay module.

Most revisions of the 2456S3 Appliancelinc and 2856S Icon On Off modules. Remember if it was on or off. With a power loss and restoration. It will be on or off depending if it was on or off when power was lost. I have a revision 4.2 of the 2456S3 module. Always powered up off. Even if it was on after a power loss. I believe in my spares there is a 2856S Icon with the same always power off action.

There where a few revisions of the 2456S and 2856S Insteon Appliance Modules. That defaulted to Off when On before the power loss. I have not seen any Insteon Modules presently sold with that action.

The schematics are for the older 2412S PLM. Though the basic information has not changed that much. The memory on the daughter boards schematic is the slower speed memory and transformer type power supply. In the 2413S it has a faster access memory chip and the F1 fuse is not installed or the newly designed one. The 2412S could also send unregulated 12 volt DC out on the serial cable. To power things like the ISY99i and ISY994i. 2413S has enough power supply issues to not have up to a 400mA output to an external device.

If the 2443 Access Points are a revision 2.0 and above. They are built on the base 2413 PLM main board. Subject to the same power supply issues we see in the 2413S PLM. They can also be rebuilt with the power supply repair information. The older ones where built on the older interface module. I imaging {but never did} you could change the caps in them and they may also work. I do have extra Insteon modules. So for now I am OK but in the future. Not sure which way to go.

Since the ISY994i does not check what type PLM it is connected to it. A working 2413S Serial Board in a new 2413U USB PLM should work. If you where using software that checked what it is connected to. It may cause an issue. As a 2413S serial daughter board in a 2413U USB PLM. Will report the USB PLMs Category and Subcategory ID. I would not try a serial port daughter board from a 2412S PLM. The link memory is on the daughter board. Has a slower speed than the memory in a 2413. Could also be the original 417 link size or the >2000 size. That seems to miss things over about 800 links. On a ISY994i. I did see Smarthome say they had some serial port failures on the daughter boards. The Revision 2.3 the serial interface chip was changed to one with a better ESD rating. V2.4 added some signal protection on the serial port. signals and the later chip.

3543 is definitely wrong. The 2413S is around 1000 and the older 2412S was around 2000 but choked in the ISY interface if over 800. How old is the PLM? That do real strange things when the power supply is starting to go bad.

Received Insteon RF signals. Get synchronize to the module receiving its Zero Crossing signal. Before being passed on or acted on. The older power line only modules. Where not rated to be used on 3 phase power by Smarthome. They did say Dual Band ones did work on 3 phase systems.

If the PLM PRO in the FCC Database ever see the light of day. Especially now that Nokia seems to be the big push. With NO information from Smartlabs. Who knows. It has a universal power supply. 100VAC-240VAC 50/60Hz. Faster and bigger Link Database. Serial and USB. I did see a reference to an Ethernet style also. On one of the Labels given to the FCC. Serial version can also supply DC, to power things like the ISY994i on the serial connector. Kind of like the old 2412S could. For now if you find one. 120VAC 60Hz.

Every module that was controlled by a HUB. Is going to have its six digit Insteon ID. In its link database. Factory Reset removes all links and you start with fresh slate.

If you have a series 500 ZWave board. It needs firmware V5. As part of the ZWave certification added in V5. https://forum.universal-devices.com/topic/33287-release-534-test-build-is-now-available/

I looked at some of the FCC Database internal photos of some Insteon modules. The LNK354GN is also in a 2472D, 2474D, 2477D, 2475DA2. Since it is not Dual Band and not in the FCC Database. I have also seen the chip in the 2450 I/OLinc. There maybe others as I didn't look at every file.

Both of the LEDs on the Network Jack should be on. If it is connected to a network and working . They may flicker when communicating on the network. If they are off. That would explain why you can't access it. The Administrative Console Screen. Is the main screen you normally see when accessing the ISY994i. Probably the ISY Launcher thees days. It boot up. It looks for a PLM and if not found would go into the safe mode but you should still be able to access it over the network.
