If you are sending or receiving a file to an HP 48 data collector and get continual �Retry� messages, there are a number of things to check to help resolve the problem.

1.  Check that the following items are properly set on the HP48 I/O Setup Menu:  IR/Wire, ASCII/Binary, Checksum Type and Translate Code.

2.  Check the data collector file to see if you have a large gap of blank (unassigned) coordinate points in the beginning or middle of the file.  If you do have a point gap, nothing gets sent to the computer as the data collector cycles through point numbers searching for a non-blank point.  This can cause a series of �retry� messages and even a �time-out� error.  To solve this type of problem, you can create a few �dummy� points within the blank point range on your data collector.  You can also try increasing the Cancel if not connected in ## seconds and Terminate if idle for more than ## seconds settings on the Advanced Configuration Screen.

3.  Check each of the items listed in the Other Communication or Transfer Problems sub-section found later in this section.
