Logger Pro for iMac and New G3 Macs

by Richard Sorensen

Apple has produced several new computers that do not have serial ports. This has lead to many questions about using our products with these new computers. After a lot of testing and revising, here is the report.

Logger Pro works fine with these new computers when used with either the ULI or the Serial Box Interface, but you need to use a USB-to-serial adapter and new versions of our software and Apple's operating system, specifically:

  • MacOS 8.5 or newer
  • Logger Pro version 1.1 (available now on CD-ROM or disk)
  • a Keyspan USB Serial Adapter

Other adapters can probably be used, but we have not tested them. The Keyspan adapter is available from most mail order Macintosh product catalogs or from Keyspan directly at
(510) 222-0131, info@keyspan.com , or www.keyspan.com.

If you are using our other software, such as MacMotion, Data Logger or Graphical Analysis, you will be able to use the Keyspan adapter as well. We had success when we connected the interface to Port 1 of the Keyspan adapter and selected the printer port setting in the software.

If you currently own Logger Pro and would like this new version of Logger Pro, you are entitled to a free upgrade. Please indicate "free iMac upgrade" when ordering. Keep in mind that Data Logger is not the same as Logger Pro. If you own Data Logger or MacMotion, you need to purchase Logger Pro (order code LP, $65).



New Version of Logger Pro
Logger Pro version 1.1 for Mac and Windows was recently released. This is our first version available on CD-ROM. In fact, from now on, we will send a CD-ROM version for all Logger Pro orders unless you specify that you want a disk version. If you have already purchased Logger Pro and want a free upgrade, check out "Free Stuff" on our
