TO ENSURE SAFETY
This Service Manual has been compiled for the purpose of facilitating repair and maintenance of the GL200
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 GL200
contains numerous internal components with a high electric potential, such work by unauthorized service
personnel could cause human injury or serious damage to the GL200 midi LOGGER.

2. UPGRADING THE FIRMWARE
The version of your GL200/A’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 GL200/A Flash ROM from the USB memory device
Preparations for the upgrade
Firmware :Mxxxa001.G20 ← Main Program file for GL200/A
:Mxxxa002.G20 ← Main Program file for GL200/A
Note:
The former firmware version of 2.00 are for the GL200.
The firmware version from 2.00 is for the GL200A.
Do not install firmware of the GL200A to the GL200.
(1) Connect the AC adapter for the GL200/A.
(2) Turn on the GL200/A.
(3) Copy the two main program files to a USB memory device from the computer.
How to upgrade
(1) Insert the USB memory device containing the main upgrade program into the GL200/A's USB port.
(2) Turn on the GL200/A 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 GL200 until this process is finished.
GL200
The following message will appear on the GL200/A 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 GL200/A when the above message is displayed or when the beeper sound
stops.
(5) Delete the two main program files from the USB memory device.
This is to avoid upgrading the firmware by mistake.
