I have a dead OmniPro II. The AC led comes on but that's it. I checked all the 12 volt locations on the barrier strip and they are 0 volts. No heartbeat led. I don't think the rest of the board is damaged. Nothing obvious. I took the eprom out and read it and its good. No smoke smell. Is there...

Are there phone lines to the two additional buildings?

I managed to get a mint HAI 1503 console in the original box. Looks like it was never installed. If you power it up it reports "System Failure". When I hook up the A and B lines, I either get System Failure or random Q's on the display. It passes its built in self test. Maybe it only works on...

Thanks, but those are OmniPro II files. I am looking for Omni 2 files. There were never any cff files for the Omni 2 as it always used eproms.

Does anyone have the 4.0b firmware or an image file for the original Omni 2? I just purchased an Omni 2 and upgraded it from 2.3c to 3.13. Failing 4.0b, does anyone have 3.14, or 3.15 or 3.16? I know it's a long shot but thought it was worth asking.

Does that imply the E11 boards will have any performance issues with less SRAM? I have a 2E and an LTe both late production boards. They have the little adapter board for the eeprom. Looks like they quit bothering to fill out the type number, rev number and serial number. The number that goes...

You may want to contact @mlester on this board for help. Also check the link below: https://pcswebstore.com/products/pulseworx-in-line-choke-filter-1-8a?_pos=1&_sid=79b0d0630&_ss=r Note this choke is only 1.8 amps. This may be closer to what you need...

Working on this table, I noticed some interesting .cff files. There is a .cff file for the OnQ HMS 950e and OnQ HMS 1100. Both are version 2.16a. I suspect these were made to allow replacement of a broken OnQ board with the newer flash memory versions of the board. This also implies 2.16a was...

After seeing the number of HAI boards mis-identified on ebay, I started working on a chart. This is as far as I got. I don't know the id numbers for the Lumina or LuminaPro. Also, my last released firmware is based on what I can verify. I believe the 4.0b eprom was released for the old Omni 2...

Anyone have a new or used 42A00-1 or 42A00-2 you are willing to sell? Insurance requirements are forcing a number of my clients to add more devices.

Ordered eproms per your suggestion. They are either new or extremely clean pulls. Blank checked and programmed fine. Thx.

Thx, I was wondering if it was compatible.

Anyone know of a US source of 27C801 eproms? 99% on ebay are from China. The few US listings show many comments about mislabeled/fake chips. Are there any OTP versions of the 27C801? I need to stick with the standard DIP package for my programmer and the HAI controllers...

Is there a chance the Elk M1ZTS might work? Its also a 3 wire device that runs on 12 volts. Temperature range is -50 to +140 which is slightly greater than the HAI.
