LogView-R Logging Utility Installation
4.8.1 Software Installation
Before installing the supplied Log View-R Data Log Utility software into your computer (the
computer must use the Windows 95/98 or later operating system and contain a USB or RS-232
port), ensure that the computer and the PathAlign-R are not connected. Windows 95 does not
support USB, only Windows 98 and later operating systems support USB. If you are running
Windows 95 use the RS-232 cable between the instrument and the COM2 port (RS-232) in your
PC. Your computer display should be set to 600 x 800 or higher.
The following instructions should be followed in the order given.
1. Close all running programs before installing utility. If you are running Windows 2000 or
XP on a network see note below.
2. Insert the CD into the CD drive.
3. Go to ’Start’, select RUN and enter the appropriate drive letter (e.g.:
D:\setup.exe
)
and click [OK].
4. At the "close any applications you may be running", click [OK].
5. At the "change directory", click on the computer box icon in the upper left corner.
6. At the "Choose Program Group" {Log View-R}, click [CONTINUE].
7. At the "Set-up was complete", click [OK].
8. Remove the CD from the drive. The utility install is now complete.
Note:
Installation under Windows 2000 and XP on a network may need to be done while
logged in as an ’Administrator’ rather than as a normal user. Windows 2000 install shows a
message that file
HID.DLL
is newer than the one in the install package. You will be asked if
you want to keep the newer file. You should answer ’Yes’ to this question.
4.8.2 Windows USB Driver Installation
After installing the logging utility, the first time the instrument/computer connection is made
through USB; Windows will detect a new device and launch its "Hardware Wizard" and search
for "USB Human Interface Device" drivers for the instrument. The following instructions apply:
