distributor or Chaparral technical support at: support@chaparralnet.com. Resolutions
to common problems you may encounter are described in the following sections.
Terminal Emulator and COM Port Problems
Problem: Screen continuously puts out garbage characters.
The likely cause of this problem is a baud rate mismatch between the terminal
emulator and the controller. The default baud rate is 115,200. Follow these steps if
you set your terminal emulator to this rate and still get garbage characters:
1
If you are able, shut down the controller.
See
Rebooting the Controller
on page 7-1. If you are not able to shut down the
controller, continue with step 2.
2
Turn
OFF
the power to the enclosure containing the controller.
3
Press the spacebar of your terminal emulator.
4
Turn
ON
the power while continuing to press the spacebar. This will allow the
controller to autodetect the baud rate setting.
5
When the Flash Utility appears, select option 5 to continue to boot the
controller.
Note:
Some terminal emulators don’t immediately change to the new baud
rate settings, and you have to exit and restart the emulator to use the new
settings.
