That was me. I used a K-type thermocouple and a scaler box to a universal 0-5V input on the CTS2. It works like a charm and has seen extreme temperatures on MANY trips to Mexico, asphalt track, and the dirt sled pulling tracks.
You will need the following (note, the first thermocouple is what I have as the 1/4" "extreme duty" option wasn't available at the time):
1) Edge 0-5V universal input and plug
2) K-type thermocouple (
Link) or (
Link)
3) K-type thermocouple scaler/amplifier (
Link)
4) Fuse tap to supply switched 12V power, note mine gave weird readings with 5v reference from the CTS power source
After you have those, enter the values off of the datasheet for the scaler box into your edge CTS2 with "my style" software to define the input. For ease of use I picked the two ends of the spectrum and allowed the edge to infer the value because it gave odd readings with many inputs. My table reads 0.00V=32 and 5.00V=2282. You will have to enter the units you want to be displayed in the table headers/my style software. If you have more than one EAS module you may have to unplug them all and only plugin the one you're trying to set up in order to verify the proper input. Besides having a more robust/reliable probe, if you ever do have a failure they are ~1/2 the cost of the edge probes and you can take your pick of ANY k type thermocouple on the market as it is a universal voltage output from the sensors.
