The EZIO2x4 is approximately 40 feet from the new device, and using 18awg wire. The manufacturer says you can run the device 500 ft with 22 awg wire or 1000 with 18 awg for 1000 ft. Yes I thought the new device was running when I first installed but soon the signal became intermittent and lately doesn't run at all. I should also note that the device is very sensitive to outdoor temperature, and I haven't been able to keep the device cold enough to start running yet. The manufacturer recommends using some freeze spray., which I must purchase.

Sorry for the confusion, but I haven't had circuit 2 working, at least unreliable at best. That being said if you want me to rewire back to "new device.pdf" anyway, no problem, but we shouldn't go back under the mistaken impression that circuit 2 was ever working. As a test I rewired circuit 2 as circuit 1 and found that the alarm behaved correctly and alarmed for circuit 2. Most of the connections were tested with this test and all seemed to work, so I'm don't believe the problem is with the EZIO2x4.

Okay, thank you, I think I understand what you are saying and you are satisfied with the most recent schematic I've sent. Now that I have a blueprint to follow, how do you suggest that I troubleshoot to figure out what's going wrong

Well I put my best foot forward, and yielded the attached schematic. I've stared at these drawings for days. As a side note, I don't understand how the optical isolation works. I seems you connect to I2 + terminal and then to I2 - terminal and the isolation hpapens forum.pdfly ?

Looks like I don't have this problem resolved yet, and it seems that the reason may be that I didn't pay enough attention to your comment about the common wire. Are you saying I need to tie together the GND to the common wire (black wire in drawing). Sorry if this is tedious. Thanks again for the help. new device.pdf

Well I think I have it working. One circuit with supply +5VDC to I1+, then I1- to external dry contact to GND on EZIO2x4 Second circuit with supply +24VDC to I2+, then I2- to external dry contact to common wire The two circuits work independently, and work appropriately by displaying the status of EZIO2x4

Well I wasn't expecting that I'd have to run a wire tying GND to the black Common. Thank you so much Brian, this forum has some enormous talent. I didn't expect to get into such deep water. I think I've had enough electronics on this project.

Perhaps this picture will help clarify. It looks to me like I just have to run the control wire to the EZIO2x4 I2- terminal and secondly connect a wire from the EZIO2x4 +5 VDC terminal to the I2+ terminal. scan1.pdf

I am connecting a device which runs on 24 VDC and uses a third wire running from the device to ground through a switch to differentiate between ON-OFF status. I was planning to use a EZIO2x4 to connect +5 VDC terminal of EZIO2x4 to I2(or I1)+ and then connect third wire from the device's control signal output to terminal I2(or I1) -. Thanks in advance

Hurray, the new EZIO2x4 fixed my problem with unstable input readings. I noticed that the module is much heavier than the first edition Thank you for your thoughts and advise.

I’ll short both I3 &. I4 and try I1 & I2 again. Sadly I have not observed any change that was useful. Both the I1 & I3 circuit are stuck at the ON state. I have both

Well what do you know, I got I3 working on the first try. Now I'll try shorting out the unused I4 and see if that works. ?

Well I have a 2413S PLM. The EZIO2x4 has got the pass-through 110v receptacle on the front face and I think it is old. I'm trying to understand how to get I3, I4 working. I was thinking of using a dry contact but I3 & I4 has only one wire so where is the circui I took out my volt meter on I1 and found the 5 volts was present when the dry contact closed. The only problem is that the state of the input monitor on ISY 994 is not showing change of.state correctly.

Where did you get your version 0f Simple Home Utility Suite v 2.03b . I seem to have trouble with my version in that it acts much like yours the first time I use it 2 x Input & 2 x Alm (I can access all four inputs) but then changes to 3 x Inputs the next time I run it. When I went to take a look at the eziomodule it was flashing like a Christmas tree. There was no state showing for I1, I2, I3 & I4 on the isy994. Another dumb question I have is how do the use (I3 or I4) as digital inputs besides adding a 10k ohm pull up resistor between terminals +5vdc and (I3 or I4.) ?

I'm using the GND terminal on the EZIO2x4. Right now i have all the ground wires twisted together with a Marr connector with a single wire going to the GND terminal. Well I tried relocating the EZIO2x4 3 or 4 feet away, but still didn't work any better. I'm still getting flaky signals. Maybe I've fried the thing with all the experimentation ?

Well I gained a lot of knowledge today but it's still not right. I double checked all my wire connections on the EZIO2x4. Perhaps if I move the EZIO2x4 away from the other devices I can reduce some interference. Thanks again.

Thanks very much. The only problem I have so far is that I4 is tied to ground but still shows "on". I may have reversed the on/off display in SHN utility at one time. Well the SHN utility only goes to Input 3, so I'm out of luck changing Input 4. lin

I seem to be having a floating state (ON & OFF) problem on the Inputs of my EZIO2x4. Pull up resistor on Isolated inputs: Many articles suggest adding a 10k ohm pull up resistor, by connecting the +5V terminal on EZIO2x4 to the I1+ (Isolated Input) terminal and then connect the I1- (Isolated Input) to my external "dry" contact and then return to the ground terminal on the EZIO2x4. This works for a while but eventually the state changes. Pull up resistor on Digital inputs: Can add 10k ohm pull up resistor between +5V terminal and D1+&D2+ but then how do I complete the circuit. Grounding unused inputs: I'm only using one input so the others should be grounded. The EZIO2x4 inputs lit up like a Christmas tree. Thanks for the help. I have failed miserably.

Well I finally got my new Schlage lock working. It certainly wasn't as easy as it should be. Kudos to the ISY wiki documentation for guiding me through the major steps of "Z-Wave Configuring Range Extenders and Door Locks". The correct order of steps seems to be very iimportant The Z-wave Aeotec Repeaters worked fine but it would sure help if the proper set of instructions was included in the box. Fortunately the proper instructions were posted on the web site, and agreed with the ISY wiki. For some reason the first try didn't work, it was connected, but not securely. I excluded and then ran included and it came up securely on the second try. I now had the Repeaters working, and tried to add the lock, but it wouldn't include, even after several includes and excludes. I finally remembered someone posting that disconnecting the battery in the lock for a few seconds, and it worked immediately.

Oh yes, I'll invest in whatever infrastructure is required to get the lock working. I just meant that my z-wave project will be limited to achieving a fully functional front door lock. I have two outlets within 6 feet of the door mechanism (one to the left and one to the right.) that would be very suitable for plug-in modules that have a security mode repeater function.

Thanks for the help guys. The learning curve for building a z-wave network was much steeper than I had anticipated. There seem to be several options on building the z-wave network to operate my front door lock. Time will tell what the best approach is, but I suspect a number of good solutions are available. I have a very old house with steel mesh and wood lath plaster walls. Relying on radio waves alone in my house will be very spooky, so I don't see much of a chance that I will expand the scope of the z-wave project beyond the door locks. Insteon & ISY have worked very well for me, although I've needed and received generous support on ISY programing from time to time.

The Aeotec ZW117 Range Extender claims to be capable of connecting securely and supports beaming.

I found the z-wave forum overwhelming, and difficult to assimilate. Perhaps you could provide links to topics you recommend.

Will a plug-in zwave range extender do the job ?

Unfortunately I don't have any other z-wave devices Are you adding the z-wave devices from the ISY console interface using "Add/Include Z-wave Device" ?
