Connection Procedures
* For details, refer to the User's Manual (PDF).
Connect the DC output of the AC adapter to
the connector marked "DC LINE" on the
GLT400.
Connect the ground cable to the GLT400
while pushing the button above the GND
terminal with a flathead screwdriver.
Connect other end of the cable to ground.
Connect the expansion terminal base connection terminal
Connect the AC adapter Connect the ground cable
1. Install the connecting plate and the
cover to the connection terminal base
with the supplied screws.
* Recommended tightening torque: 14kgf/cm
2. Direct-connect the terminal base to the
GLT400. It is recommended to
direct-connect them on a flat desk.
Then, connect the connector cover to
the expansion terminal base.
3. Assemble the cardboard contained in
the accessory bag to make a spacer.
4. Turn the direct-connected GLT400
over and place it on the spacer as
shown in the figure. Tighten the
screws without rattling. (When
connecting multiple GLT400s, ensure
a height of 33.5 mm without rattling.)
5. Insert the terminal into the terminal base.

<How to mount> <How to remove>
• To remove the SD CARD, confirm that the "SD ACCESS" LED is not lit and then remove it.
• When replacing the SD CARD during capturing, follow the replacement procedure.
In USB DRIVE mode, the GLT400 operates as an external drive for internal memory and SD
CARD.
If using our application with a USB cable, you need to install the USB driver on the PC. For
the installation, refer to the "USB Driver Installation Manual".
To connect the GLT400 to the PC, use a cable with A-type and B-type connectors.
Connect the USB cable
Mounting SD CARD
1. Remove the SD CARD
protective cover.
1. The SD CARD is released by
pushing gently on the SD
CARD. Then, pull to remove
the SD CARD.
2. Insert the SD CARD until it
clicks and is firmly placed
inside the slot.
* Confirm that the writing is
not locked.

Warming-up
Safety Guide for using GLT400
If a voltage exceeding the specified value is input, the semiconductor relay used in the input
section is damaged. Never input the voltage exceeding the specified value at any moment.
GLT400 requires approximately 30 minutes warm-up time to deliver the optimum performance.
