Testo® 523 To PDA Communications Loop Modification

June 29, 2008 · 2 Comments

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.

The files above are in the Winzip and Winrar formats (respectively) that require you to decompress the folders after you have them downloaded on your system. Most operating systems are included with a compression/decompression (codec) that will decompress these files.
