AI-generated application scenes illustrate possible settings, not customer installations or installation specifications. The two field photographs above show actual deployment environments.
Start with the physical format, then confirm code source, credential mix, host interface and mounting.
| Model | Display | Core use | Credentials | Interface / mounting |
|---|---|---|---|---|
| FC6820 | 3.33-inch touch display | QR and card access with an on-device interaction point | QR code, password and card options by configuration | 86-box surface mounting; Ethernet, RS485, Bluetooth and optional Wi-Fi |
| FC6822 | 3.33-inch touch display | Integrated QR and card input for flush-mounted installations | QR code, password and card options by configuration | Flush mounting; Ethernet, RS485, Bluetooth and optional Wi-Fi |
| FC6825 | Compact touch display | QR and card workflows that need clear on-device feedback | QR code and card options by configuration | Installation and host interfaces are selected for the project |

Match the baud rate, data format and electrical interface on both sides, then inspect the cable and any serial-to-USB adapter. Also confirm whether the reader is sending raw content or a framed protocol message before treating additional bytes as corrupted data.
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.
Yes. Single-read and interval modes can treat repeated presentation of the same code differently, while a different code may still be accepted immediately. Confirm which modes and repeat intervals are available for the selected reader before defining the user flow.
Do not assume so. Reader firmware and access-control firmware can use different tools, configuration codes or platform commands. Share the overseas model, firmware and intended operating mode so the matching method can be checked before changing settings.
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.
Not necessarily. Identity enrollment and access permission are separate steps in many systems. Confirm that the person, credential, target device, schedule and permission group have been linked and that the authorization was delivered successfully.
No. A device can have local network access without maintaining its platform or messaging connection. Check the physical network, IP settings and service connection separately, using the indicators or logs available for the selected system.
Compare the RS485 wiring, polarity, grounding and communication settings with the instructions for both devices. Then confirm the reader output mode and controller input configuration; a correct cable cannot compensate for mismatched communication settings.
Configuration, compatibility and delivery scope are confirmed for your project.
