Installation Instructions for LI-6400XT Upgrade
Before You Begin
The LI-6400's digital board contains, among other things, some instrument specific calibration
files. Therefore, before changing digital boards, it is necessary to download these from the old
board, and then upload them onto the new board once it is installed. In addition, you may have
data or configuration files that you want transferred from the old memory board to the new one.
Do the following steps to accomplish these transfers:
Windows Instructions
1. Install the LI-6400 File Exchange program (if you have not installed it previously).
Place the LI-6400 Software CD in your PC. If it is not there already, select "LI6400 Applica-
tions" in the drop-down menu under Install PC Software (Figure 1). Then click on the 'Go'
button.
Figure 1. Choose 'LI6400 Applications' and click 'Go' to install the File Exchange software.
2. Connect the LI-6400 to a PC
This requires the 9975-016 cable that is shipped with the LI-6400 (Figure 2).
