TO ENSURE SAFETYThis Service Manual has been compiled for the purpose of facilitating repair and maintenance of the GL800

midi LOGGER by Graphtec service personnel and other persons who have undergone equivalent technical

training.

Maintenance or repair by unauthorized service personnel is to be strictly avoided. Because the GL800

contains numerous internal components with a high electric potential, such work by unauthorized service

personnel could cause human injury or serious damage to the GL800 midi LOGGER.

2. UPGRADING THE FIRMWAREThe version of your GL800’s firmware can be upgraded by rewriting the flash ROM on the pertinent circuit

boards. You can upgrade the firmware by loading the update program to a USB memory device.

2.1 How to Upgrade the GL800 Flash ROM from the USB memory device

Preparations for the upgrade

Firmware :Mxxxa001.G80 ← Main Program file for GL800

:Mxxxa002.G80 ← Main Program file for GL800

(1) Connect the AC adapter for the GL800.

(2) Turn on the GL800.

(3) Copy the two main program files to a USB memory device from the computer.

(Copy the two main program files to root directory of a USB memory. Do not copy them to any folder.)

How to upgrade

(1) Insert the USB memory device containing the main upgrade program into the GL800's USB port.

GL800-UM-251-9370 2-2

2. UPGRADING THE FIRMWARE

(2) Turn on the GL800 to automatically execute the upgrade program.

(3) Wait until the display shown below appears or until the beeper sound stops.

Note:

Don't turn off the GL800 until this process is finished.

GL800

The following message will appear on the GL800 display in yellow characters when the upgrade is

complete. Also the beeper will sound for 5 seconds.

“Please Turn Off the Power. I have locked up.”

(4) Turn off the power to the GL800 when the above message is displayed or when the beeper sound

stops.

(5) Delete the two main program files from a USB memory device.

This is to avoid upgrading the firmware by mistake.
