| Alarm Note | Number of Alarms: 8 (one per digital I/O line)
Alarm Functionality: Each alarm controls its associated digital I/O line as an alarm output. When an alarm is enabled, its associated I/O line is set to output and driven to the appropriate state determined by the alarm options and input temperature. The alarm configurations are stored in non-volatile memory and loaded at power on
Alarm Input Modes:
• Alarm when input temperature ≥T1, reset alarm when input temperature |

Good Hardware - Good Price - Software Not So Good
The Omega hardware has proven itself to be reliable and well developed. I wish there was at least one more
set of software support possibilities that would support their hardware better than the InstaCal/TracerDaqPro combination.
The software is not user friendly. Depending on how you move thru the programs, you can easily lose data. It is very sensitive
to the sequence that you add/change data that is pertinent to both applications. Lastly, the application restricts thermocouple
support to 48 channels. There should be an alternative selection/or software that supports more than 48 channels.

Works but label was rotated
Same issue as the other 2 reviews: got an "open connection" error when trying to test the analog inputs, and when I rotated the connections 180 degrees the error went away. Very annoyed at Omega.

Works but connector label is applied wrong
I had the same experience as reviewer Clearw. However, I discovered the problem - the I/O label is rotated 180°. Just mentally rotate the label so that CH0H is at the front right and CH7L at the rear right when you look at the device from the end with the power connector.
The attached photo shows the device hooked up to working thermocouples. As you can see, the TC wires are on the connector block on the right when you hold the power connector toward you.
Once you do this, the device works fine, at least the TC inputs. Presumably the connector block on the left has the digital I/O etc. but I didn't check that out.
The photo of the device on the Omega website actually shows the label affixed correctly - although I only discovered that after I had figured out the problem from other clues. (It did not make sense that the jumper for the digital PU/PD option was on the opposite side of the circuit board from the digital I/O, and when you look at the circuit board, the connections labeled for differing functions all appeared to have identical board topology, which is what you would expect for the TC inputs.)
This should be embarrassing for Omega. They have had a month since Clearw posted his review and they haven't posted a correction. Their own photo on their website is different from the device I received, so somebody there has realized it but not told the service department.

Did not work correctly right out of the package. "open connection" error messages.
