Light-Emitting Diode Indicators (Leds) - GE GCG001 Quick Start Manual

Firmware Load Pushbutton
The Firmware Load Pushbutton is used to initiate loading of module firmware from the SD
card as described in the next section.
Loading New Firmware
To load new GCG001 firmware, the SD card must be moved to a computer. Copy the
firmware image to the card, then re-insert the card into the unpowered GCG001's SD slot.
Next, while holding down the Firmware Load Pushbutton, apply power to the module.
Continue holding the pushbutton until the OK LED turns amber, then release the pushbutton.
When the OK LED turns green, the firmware is loaded. Finally, cycle power on the module and
wait for the OK LED to turn green and steady.
