But it needs to be configured for the correct senders. Chances are that you could install the resistive senders and be good to go. (This is what is in my 252). But if you're doing the work, it might be better to go digital and at the same time send the EDM900 back to JPI for a firmware change to support it. I think there is a charge for that though. Talking to JPI would be appropriate. 1 Quote Link to comment Share on other sites More sharing options...

At some I would suspect they started shipping unit’s with the required firmware. I would recommend as Paul suggested that you go with the frequency mode. This will require a special cable. I created a CiES thread about the process. I will look for it and post it here. Sent from my iPhone using Tapatalk Pro 1 Quote Link to comment Share on other sites More sharing options...

hypertech Posted July 1, 2020 Report Share Posted July 1, 2020 Did this a couple weeks ago. It depends on how old your 900 is. Mine already had the necessary firmware (~2 yrs old) and all they had to do was wire it up and switch the config over to frequency based.

I called CiES and they advised me based on the age of my JPI900 Sent from my iPhone using Tapatalk Pro Quote Link to comment Share on other sites More sharing options...
jlunseth Posted July 2, 2020 Report Share Posted July 2, 2020 I made the switch about a year and a half ago. Unit had to go in to JPI and came back looking new. My unit was about 8 years old by the time it went in. Newer units, I guess, can use the frequency based probes but the older ones need to be changed. Probably serial number based. JPI has been very slow during the COVID shutdown, so I would check with them to see how long it might take. The charge was nominal, maybe $350, I don’t really remember.
