Can I cut an FC8134 panel opening from the product image?
Use the model-specific dimension drawing, not the photograph, to prepare the panel. Confirm the opening, panel thickness and fixing positions, plus rear clearance for the body, connector and cable bend. Request the FC8134 drawing with your host and configuration details.
Why can output differ from the original QR content?
A reader in transparent output mode may send the original content, while a protocol or development mode can add a header, length, device information and check data. Select the mode that matches the host application and use the protocol reference for that model and firmware.
What should we check when a reader does not react to a code?
First confirm that the reader has started normally and that the code is complete, correctly generated and presented within the usable reading area. For codes shown on a phone, raise the screen brightness and remove glare; if known-good codes still produce no response, record the indicator and buzzer behavior for support.
