The Texas Instruments CD74HC4051E is a direct replacement and is in stock at Digi-Key: https://www.digikey.com/en/products/detail/texas-instruments/CD74HC4051E/475938 If you go to either Digi-Key or Mouser and type the part numbers into the search box, they may be able to find substitutes for...

Mine always says "Retrying..." during the erase cycle. I think it's because I have 990 lines of code loaded; it takes longer than the timeout period to erase. But it always works eventually if I leave it alone.

A lightning hit last night disabled all three of my Omnistat/2's, two RC-1000s and one RC-2000. The behavior is that they no longer appear to have power: nothing on the displays, no backlight, no response to controls, no date being sent to the OPII, nothing. I verified that all three of the...

I have a ton of UPB-controlled lighting. Seems like that's falling out of favor too; PCS seems to be the only manufacturer remaining that still makes UPB devices, and they're expensive. It seems like if I have to replace the OP2, I'll end up having to integrate a system myself, with an Elk and...

I would not set up a water alarm system to shut off the power to the washer, if it's already shutting off the water. First, as already noted, modern front loaders don't hold much water. Second, if the drain hose falls off the back of the machine, it will run out anyway -- residential washers...

The first thing to check is to see that the new one is set to the same unit number as the old one was. Did the old one fail due to a lightning strike or some other electrical calamity? A couple of years ago I lost an RC1000 due to a lightning strike, but it also damaged the motherboard in my...

Hope all of you guys and gals at HAI are okay.

That's just as well. Most routers expire DHCP leases after a period of time (24 hours with mine), and the 5.7e doesn't have the ability in the current firmware to request a new one. Configure it with a static IP address and there's no problem. That's really the way it should be done anyway...

Yeah, bypass the zone. That can easily be done from the console or from PC Access. If it's going to be a while before you can get the zone fixed, change the zone to auxiliary in PC Access.

You can also write code to trigger on links and do a REQUEST STATUS on the units effected by the link.

I have a feature that I'd like to request for consideration in some future version of the OPII software: the ability to enable auto bypass on a per-zone basis. Here's what is motivating this: for some zones it may be possible for programming to take some action to make the zone secure when the...

The one thing that comes to mind is an intermittent short on something connected the console bus or one of the remote power busses. Do you have any zones configured as tamper zones?

That won't work the way you're trying to do it. The Omni zone input is a current loop; it does not expect the connected device to be applying voltage to the loop. What you need to do is wire a relay into the EZEye's output. Connect the white wire from the EZEye to one of the coil terminals on...

Another possibility, if you have any UPB, is to use a UPB I/O device, e.g., the Web Mountain CM-01.

You could trigger on the OFF event for the lights. Something like: WHEN Landscape Lights OFF AND IF DARK THEN SET LIGHTING LEVEL Landscape Lights TO 20% As you might suspect, IF DARK is true between sunset and sunrise.
