I replied to you on the list but am posting here in case some1 else see it or searches for an answer in the future.
The Ibuttons are DS-1992.

The company I work for uses the scratchpad memory in them to store "codenames" for laser tag gameplay.
An example of a "members" button of scratchpad data would be
10 31 39 50 61 74 74 79 43 61 6B 65 73 34 38 31
32 36 31 32 30 34 30 30 30 04 30 36 3D 33 03 20
DECODED =
19PattyCakes481
26120400006=3
.

The "non members" button are similar to the data. All the data I need to extract is the "PattyCakes" part. It will be 10 characters long. Skip first 3, read 10, skip last 19.

I have already received the serial number. (got the lcd to display it)
