When using the PSI software, the Current Status Screen, All Points History and the graphic data display screens do not properly display the text shown on that screen.
- PSI software
The video bios in the computer does not support the graphics mode used by the graphic displays of the PSI software products.
This problem was first identified several years ago on some models of Gateway brand laptop computers. The problem has been observed from time to time, since then, on various computer makes and models. The problem affects both the "Current Status" screen, the "All Points History" screen and the graphic display screens for analog I/O points. There is no software workaround for the problem.
The best solution for this problem is to evaluate the computer model before purchasing any quantity of them. Download test program vga_test on The Exchange Download Center, which allows testing of the computer without having to load the PSI software. The test program can be run from any removable media (diskette, CD, memory-stick, etc.) so the computer can be tested at the computer dealer's store or sales office. The text file included in the zip file explains how to run the test and how to interpret the results.
