Testo® 523 To PDA Communications Loop Modification
We are interested in talking to anyone that has either successfully modified the IR communications loop betweeen the Testo® 523 and it’s printer to include a Palm or other PDA device, or anyone that is currently attempting to make this modification.
You can either respond directly to this post or contact us via email at digital.zeus@yahoo.com - you do not have to disclose your identity if you elect not to.
I know there is at least one technician that successfully made this modification, unfortunately I have lost contact with him as a result of a system crash, so it can be accomplished. Thanks for any input relevant to this topic.

Thank you Buck – appreciate the reply and the information you have provided. I have been doing some research into the protocol that Testo utilizes in their IR capable instruments and at least as far as all of the information I am able to review the protocol, while proprietary in some respects – appears to be applied acros their entire communicating instrument lines.
I would venture to say if you have achieved a degree of success with the 556 it will also be applicable to the 523 – can’t wait to see it in action.

Yes it is possible. I have developed a prototype application that will read the data from the Testo 556 IR Printer port to a Palm based PDA.
I am just cleaning up a few of the database features (saving collected data), and will then share it with a few folks for some testing.
