Operation
Power Up
The GGC unit output messages can be read by using a terminal program. Now it is time to power
up the data collection computer and start the terminal program for the serial port connected to the
GGC. Next the power needs to be switched on for the GGC unit.

Initialization
Ideally, the GGC should be stationary and level when it is turned on. If not, the sensor readings
may not be immediately accurate after initialization. The time required for the initialization
process takes 4 to 5 seconds. During this time, a message is sent from the unit via the RS-232
serial link. This message gives information about the GGC such as the full model number, serial
number, and software revision.
