The pass through outlet on the EZIO2x4 is an older 2412 base board. The 2413 base boards had issues and Smartenit went back to the old 2412 boards made for them. PLM using the utility does not matter. Unless the PLM has bad caps. This is for the I1 input and dry contacts. https://smartenit.com/wp-content/uploads/2018/04/EZIO2X4-Dry-Contact-Connection.jpg. I 2 would be the same as it is also an isolated input. I1+ should always read 5 volts. I1- should change from close to 5 volts contacts open and nearly 0 volts when the contacts are closed. I think the v2.03b had its screen name changed to Smartenit. I have a copy of 2.02e and its screen still said Simplehomenet. Digital inputs. You connect the digital input (I3 or I4) to the digital source signal and the GND terminal for the digital sources common. Remember a digital signal is from 0 volts to 5 volts. 0-1 volts is Off and 3-5 volts is On is the way I see digital levels. Smartenit says 0-1 volts is On and 3-5 volts is Off. In their users sheet for the module. The utility does allow you to set the input to an Analog. If you really want to use a digital input and dry contact. Connect the digital input to 5 volts through a pull up resistor and the dry contacts to the digital input and GND. The input will be inverted. Open will be On and closed will be off. Not recommended due to noise and possible 5 volt supply protection issues. You could pull the input to GND with a resistor and then use the contacts to switch the 5 volts into the input. That way open contacts would be Off and closed On. The Smartenit information does not follow what I call a digital signal. So the On and Off status maybe reversed. Depending on how they implemented the signals status.

There is no I3- terminal. It is one of the two Digital- Analog inputs and are not an isolated input. Where you can tie the + input to +5 and the - input to GND through the dry contacts. I1and I2 have both a + and - terminal.

2.03 was on the SimpleHome Net Forums. That is now defunct. SourceForge where I may have gotten 2.03 also now has 2.0. https://sourceforge.net/projects/shnutilitysuite/ The version on the sales site is 2.0 and I don't think there is much change between the versions. Are I3 or I4 being driven by a Digital signal driver? Is your EZIO2x4 built on the older power line only 2412 base board or the 2413 Dual Band base board? If it is a 2413 base board. It will be subject to the same power supply capacitor issues we have seen in the 2413S PLMs.

Is the module stable if you have no wires on it? Like unplug the wiring plug from the module so no wires are connected. I did see reports of a floating Analog Input causing issues and why connecting to the GND was recommended if not being used. If it is one of the Analog inputs. It is 0-5VDC. Can't say for sure if a higher voltage spike may have effected it.

This is probably a stupid question on my part. You are using the GND terminal on the unit and not a safety or power line Ground?

What revision SHN Utility? My 2.03b and an old EZIO2X4. Shows two Analog and two Isolated inputs. AN1, AN2, Input 1 and Input 2. A configuration area where you have to enable the Analog Inputs. That are defaulted to Off and can't be read. If you are not using the second input. You don't have anything on I2+ or I2-?

No 10K resistor needed for the Isolated inputs. They have a internal resistor to limit the current into the Opto isolator. 3-30 volts DC is the input range. Connect I1+,I2+ to the +5 volt terminal. Dry connects from I1-,I2- and the GND terminal. If you are only using one of the two isolated inputs. The second one should not have to have its inputs tied to ground. Tie the analog inputs if not used to GND terminal. No resistor needed. You asked about the Analog input connections. The analog inputs are between the Analog terminal and the Ground terminal.

Let us know how it progresses. The 27 Ohm 2W is a good choice. The 1 Watt may also be OK. I did see a reverse engineered schematic of the 2856S Icon On Off module. As that 27 ohm resistor is in many of the older Insteon modules. By the physical size. They though 2 watts.

OK. The voltages you posted are a good reference as to what you want to see. When testing you don't have to have the daughter board connected. It would probably get in the way and make it harder to troubleshoot. The C7-C13 voltage maybe slightly higher with no daughter board. As the unregulated +12 volts powers the serial or USB daughter board. That has its own +5 volt regulator. If the PLM you are testing is V2.3 or lower. On the serial board you can measure the unregulated +12 volts. The metal tab on the regulator IC is common and one of the unused F1 Fuse positions is the voltage into the board.

C3 High Voltage supply looks fine. C7 and C13 unregulated 12 Volts is fine and typical. C8 +5VDC Logic Supply is with in normal tolerance. C11 Zero Crossing Detection. Probably fine. I looked at the circuit for the older 2412S. It was around that voltage. Did you have the serial daughter board connected when the LED faded out? I think I saw a post here. With out the daughter board connected. The LED did not light but that is a fading memory. I had seen some reports of the serial chip failing. The V2.3 had an improved IC on it. V2.4 and V2.5 have a new serial board. That has the new serial port IC and some signal protection to the outside world. I did a current test on my 2413S in use with the ISY994i. During a system query. There where short bursts of 600mA AC to 900mA AC .

Well I did a test. 2413S PLM not connected to serial port, just powered up. True RMS Meter reading total AC current into the AC input and calculating the voltage on a 27 Ohm resistor and AC input current Just powered up and not processing anything. About 50mW. So for testing a 1/4W maybe OK for tests.

You may want to get the Power Integration data sheet on the LNK354 switching supply IC for reference. https://www.power.com/sites/default/files/product-docs/lnk353_354.pdf Hopefully the Drain and Source of the internal power FET are not leaky or shorted. The Amazon resistors maybe too low a wattage. 1/4 Watt may overheat. Making it hard to determine if the problem was caught and it just over heated.

Found this. I would check the dimensions as I don't know about the space to mount it horizontally like the later revision models. https://www.mouser.com/productdetail/united-chemi-con/ekzm500etd101mhb5d?qs=LzZkAsBncKb0dUGUMFIpLg%3D%3D

Looked at a board. Mine are screened R1 and R10. I don't know if the schematic part numbers where what is screened on the board. The original hardware versions where 10uF 35V capacitors. So 10uF 50V should have worked. IMHO. They tried to fix the power supply issues. By increasing the capacity to 100uF and 35V then 50V. Using the same Fujicon RK series capacitors. Starting at V2.3. They changed to a Fujicon TY series 100uF/50V. The TY is rated to be in a switching power supply. I am not too clear on the schematics parts labels matching what is screened on the PCB. I will see if I can find anything on the 27 Ohm. It was used in many modules. I did see it called a 27 Ohm 1/2 watt Anti Surge on the 2412 main board in the developers notes. Unfortunately it was a surface mount and only for the small current Zero Crossing supply. The Panasonic part number would not be a good one for a 2413. I would measure the original resistor and see if it is open or changed value. As the goop the put around the wires turns brown or blackish and maybe on the resistor also.

There is a power supply area schematic in page 12 of this very long thread. Post 282. The rev 1.1 is the later of the two. Yes it is a 27 Ohm resistor. Red Violet Black 27 Ohms Gold 5%. Used as a fuse and surge reducing. Maybe dark but can you verify it is actually open or very high in resistance. It may have some flame rating and don't know the wattage off hand. Depends on which resistor is burned as to what it was protecting. My guess is R2 in the schematic as it is in the main power supply. R10 in the schematic is for the small Zero Crossing supply. Was the 10uF/35V you used for C7. The input for the filter? My thought are it was not a good capacitor for switching power supply use. It failed and maybe overloading the R2 protective resistor. Or you had a short from replacement soldering. Can't say to what 100uF/50V capacitors being used lately. As some of the originals use are no longer manufactured. One made for switching supplies, 105C or higher and long life ratings would be best.

For me. The portal sign in used my email address on file and a portal password. The first time I used it. It asked to verify my forum pass word I can't remember if the forum users name was also asked.. After that the portal credentials got me into the forums.

If you typed AB:CD:EF. Try AB.CD.EF and don't forget to wake it up as it is a RF device and goes into a power down battery saving mode. Unless you have them on a USB power supply and they stay awake.

Yes. I have one on my UPS. In my case. The UPS AC power is using the filtered output on the bottom and my PLM is in the unfiltered outlet on the front.

The module uses the 120VAC Line into the Sense Wire to control it. I doubt a 12V signal would work and it would have to be 12V from the sense wire to the Neutral power feed. Your second thought sounds better. A relay with the proper voltage coil. Could be wired to the 12 volts and have the relay contacts switch the AC Line into the module as you mentioned. Just use caution to do safe wiring as 120 Volts is involved.

Anyone purchasing the latest revision 2477S Dual Band On/Off switch. Will find a new face plate on it. Just the On and Off light pipe positions are on the face plate and all the unused pipe positions are no longer there. I have not seen any confirmation the face plate from an older one with all the pipe positions can be retrofitted to the presently sold ones. If anyone is using the 2400LF Frosted Light Pipe Kits. They are still available. New sales site says 692 kits in stock. They look like the ones in the dimmers and older On/Off models.

Is the old switch a 2476S, 2476D, Icon 2876S, 2876D, or a ToggleLinc? They are power line only models. All the presently sold ones except the ToggleLinc are Dual Band. Both power line and RF communications.

Power strips like the one you linked to. Don't normally have any AC spike suppression or noise filtering in them. It is the filtering components in the surge strip that can absorb the Insteon power line signals. Mine had a .1uF AC rated capacitor across the AC input. That absorbed the signals. I removed them. It can be very confusing as you have seen. Some surge strips just have the MOV across the AC input and maybe each AC input line to the ground pin. They would work fine as there is no filter across the AC to kill the signals. I have seen that type with no filter. No surge mentioned on the package meant no filter or surge suppression. Watch the AC input for many UPS units. They frequently have a nice big capacitor across the AC input. So they too can kill the signals. I have mine feed through a FilterLinc and my PLM in the front unfiltered output. From the description on the strip you are looking at. It is a nice metal cased AC power strip and doesn't have a filter or surge features built in.

I got the same expired certificate message. For the ISY Portal to sign in. I used my old forum name and password method to get here.

The label on the bottom should have the ZWave module is installed in the part number. On the later models there is a screw under the model label near the back edge. I had to punch through one of mine to open it. Here is some information on the ZWave board, installing if you bought it separately or just want to see the general information on it. https://wiki.universal-devices.com/index.php?title=Z-Wave:_Ordering/Assembly_Instructions Unless the Amazon vendor added a module. The box's label would indicates it was not a ZWave enabled ISY994i from the factory. The $1.00 purchase would enable a board you purchased separately and add it yourself.

I can't help you on if it would work. I don't think the Sensor Input on an I/OLinc is fast enough to see a rapid On, Off, On sequence. I would not be too surprised if it had a small time delay detecting changes. So contact bounce didn't cause errors. I don't think I got an I/OLinc Developers Notes paper. I can check and see if I have anything on it. I did a reverse schematic of the Sensor Input just to see how it roughly worked.
