Problem Recommended Action Page
The keyboard does not work. Check the USB cable and connector. Detach and reattach the keyboard. Verify a
good connection. Cycle power to the terminal.
Keyboard keys may not be enabled as
expected. Check for enabled Alt-Ctrl keys. Enter Configuration mode and select Terminal
Settings>Input Devices>Keyboard. 54
The keyboard is not accepting key input. Check the key input using the keypad.
•
If the keypad works but the keyboard does not, the keyboard driver or
keyboard is not working.
•
If both the keypad and keyboard are not working, the problem is probably
with the application.
The keyboard is a keyboard/mouse USB
composite device. Attach a standalone USB keyboard.
The USB keyboard may not be a compliant
device. Replace the USB keyboard. Try a different model or manufacturer. If a new
keyboard resolves the problem, then the old keyboard was probably
noncompliant.
Refer to Appendix B for a list of valid USB devices that are compatible with the
terminal.
You can also check the Knowledgebase at the
http://support.rockwellautomation.com site for a list of USB devices that are
