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.
