G4LC32 User’s Guide
LCD Display
The G4LC32 front panel has a green, backlit 4-line by 20-character LCD display. The display and the keyboard
together make up a terminal for data entry and display. Each character on the display is a 5 x 8 dot matrix which can
display the complete ASCII character set. Upon power up, the following message is displayed:
SYSTEM DIAGNOSTICS
Then the message:
DIAGNOSTICS COMPLETE
If everything checks out correctly (but you do not have ARCNET connected), then the display will show a message
similar to the following:
DISPLAY REV: 1.11
Mistic Kernel 1.39
No ARCNET activity
or if you are connected to ARCNET and the network is up and running, you will see:
DISPLAY REV: 1.11
Mistic Kernel 1.39
system ready
You can ignore the “No ARCNET activity” message if you do not have ARCNET connected. The above messages will
vary depending upon the revision level of the front panel display EPROM, and upon the revision level of the last
downloaded upgrade to the Flash EPROM.
During SETUP, the display is used to prompt you to enter the setup parameters from the keyboard.
If you are running Cyrano 200 or OptoControl and you have downloaded the terminal task to the G4LC32, then the
display is used to show parameters from your application’s program, such as the value of a variable, the status of an
I/O point, etc. For more information on using the display in terminal mode, see the Cyrano 200 or OptoControl
manual.
