OFFLINE
Mode provides access to the GLC unit’s Initialize menu, Self-Diagnosis
menu, and other GLC features. You will need to change the GLC to
OFFLINE
mode before you can use any of these features.
OFFLINE mode is unavailable in a new GLC until the necessary System
data has been transferred from the screen creation software on your
PC. To transfer system data, the GLC unit’s power cord must be plugged
in. When you transfer screen data from your PC to the GLC, the GLC
unit’s System data is also automatically sent.
For information about transferring data to the GLC, see
Chapter 4 –
“Data Transfer,”
or refer to the
GP-PRO/PB III for Windows Opera-
tion Manual
(included in the GP-PRO/PB III C-Package).
