Troubleshooting 8-7
Problems with Attached Keyboard
This section provides tips on how to isolate problems with the
Keyboard.
• Check for enabled Alt-Ctrl keys. From Configuration Mode,
open Terminal Settings>Input Devices>Keyboard>Keyboard
Settings.
Are the keys enabled as expected? Check all configurable
settings in Keyboard Properties.
• If the keypad is present, check input using the keypad. If
the keypad works, but the keyboard does not, then the
keyboard driver or keyboard is probably not working. If both
the keypad and the keyboard are not working, then it is
probably an application problem.
• Check the USB cable and connector. Detach and re-attach the
keyboard. Insure a good connection. Cycle power to the
terminal.
• Is the keyboard a USB composite device? If the keyboard is a
keyboard/mouse composite device, then try a stand-alone USB
keyboard.
• Replace the USB keyboard. Try a different model or
manufacturer. See Appendix B for a list of compatible
keyboards. You can also check the Knowledgebase at the
http://support.rockwellautomation.com site for a list of USB
devices that are compatible with the terminal. If a new keyboard
resolves the problem, then the old keyboard was probably
non-compliant.
