Installing the device
The ED-MONITOR-070C device supports front embedded installation. The standard packaging does not include the embedded installation Mounting kit (ED-ACCHMI-Front). Please purchase the ED-ACCHMI-Front kit in advance.
Preparation:
The ED-ACCHMI-Front Mounting kit has been acquired (includes 4 × M4*10 screws, 4 × M4*16 screws, and 4 snaps).
A cross screwdriver has been prepared.
Steps:
- Determine the cutout dimensions on the cabinet based on the ED-MONITOR-070C’s size, as shown in the figure below.
- Drill holes on the cabinet according to the aperture size defined in Step 1.
- Embed the ED-MONITOR-070C into the cabinet from the exterior side.
- Align the screw holes (non-threaded) of the snaps with the snap mounting holes on the device side.
- Secure the snaps to the device.
Use 4 × M4*10 screws to fasten the snaps to the device by threading them through the non-threaded holes and tightening them clockwise.
Then, use 4 × M4*16 screws to secure the snaps to the cabinet: Insert them through the threaded holes of the snaps, press against the interior side of the cabinet, and thread them clockwise until fully tightened.
Using the device
The ED-MONITOR-070C requires a PC host for operation and does not require driver installation. Connect it to the HDMI output of a PC host first, then power on the device to enable normal display. It supports backlight adjustment via dedicated buttons and software.
