USB interface: 2 USB host ports (for connecting printers and USB drives for data storage or printing), 1 USB device port (for connecting to a PC to transfer applications or recipes);

CF card interface: used for extended storage, can store application backup, recipe data, etc.

Core operational functions (including debugging and maintenance)

1. Self Test

After the device is powered on, it automatically performs hardware self-test and the screen displays the test results. The following items should be focused on:

Key detection contents: RAM, battery status, BIOS checksum, firmware checksum, application checksum, communication ports (COM1~COM3), real-time clock (RTC);

Fault handling: If a certain item displays "Failed", follow the prompts to troubleshoot (such as firmware/application verification failure requiring re download; communication port failure requiring checking wiring and DIP switch);

First use: The real-time clock (RTC) needs to be manually reset to ensure time synchronization.

2. System menu operation (SW7 needs to be set to ON)

After self checking, enter the system menu and provide 5 core functions that need to be operated through the touch screen or function keys:

System menu command function description

Link establishes communication connections between devices and external devices (such as PCs, other CP450s)

F2- Configure real-time clock (date, time) and communication parameters (baud rate, data bits, stop bits, etc.) using the directional keys to select fields and the ± key to adjust values

F3- Copy copies the application program of the current device to another CP450, requires connecting the download cable and entering the password

F4- Set calibration touch screen (touch the top left/bottom right corner and center of the screen), this operation will clear RAM data

F5- Run the user application and exit the system menu

3. Application download and upload

(1) Download the application (PC → CP450)

Prerequisite: The formula length and quantity must be defined in the application, and the existing formula format must be uploaded before editing a new formula.

5. Password management (4 scenarios)

CP450 supports multi-level password permissions to protect application and operational security. The key scenarios are as follows:

Password scene configuration method and permission instructions

The startup password (SW6=ON) is created in CP400Soft using the "Action Button" to create a password table. The registration password and user level (levels 1-9) are highest at level 1 (the password table can be modified) and lowest at level 9; You need to enter a password to start up, otherwise the application cannot run

During operation, use the "Action Button" to create a password keyboard button for permission switching. Press it and re-enter the password. Updating the user level can temporarily increase/decrease permissions (such as entering a high-level password for key functions)

Button password protection: Set permission levels for buttons (such as Goto Screen) in CP400Soft. Users with lower levels need to enter a password to restrict access to key functions (such as parameter modification and system settings)

When setting the password for copying/uploading applications (F3 Copy) or uploading applications (File/Upload Application) on the "Application/Workstation Setup" ->"Password" tab of CP400Soft, this password is required
