2.Through the Tools menu the user may choose to upload, or download as needed.

7.2.4Pass Through

During boot loader, the Centurion controller allows users to remain connected to both the PC and the C3-3 Display and update the two devices with a single connection.

During a download from the MConfigPro software, the user downloads to the C3-3 Display without entering boot loader mode and upon transferring the message, the Centurion controller is directed to accept the mes- sage through one port (Port 2) and pass it through another port (Port 1) directly to the C3-3 Display, as if the PC and C3-3 Display were directly connected.

Firmware Download Screen

Firmware updates for the C3-3 Display require a USB con- nection. While boot loader mode for the display is not required for configuration downloads, it is required for firmware updates.

The bootloader can be entered by menu selection if the USB cable is currently connected, otherwise the C3-3 Display will reset and restart the current application firmware. Optionally, the bootloader can be entered by connecting the USB cable and cycling power. (This method will leave the display blank while in the bootloader.)

Upon entry to the bootloader, all communication to the con- troller will stop. There is a red status LED below the USB con- nector that will blink three times and then remain on while the bootloader is active.

While a file is being transferred, the Com 2 transmit LED will appear to be lit continuously. A successful download should complete in approximately five minutes.

Special 35 Jump Code

C3-3 Display allows a “Download Only” password that will allow access to the download menu. The password is set to a fixed value of 35. Once at the Download Only screen on the C3-3 Display, the user will select to download a firmware update.

Super User Menu

Super users will use the super user menu to download firmware updates.

All normal communication with the controller is stopped while in download mode.

The display will indicate the transfer is complete by displaying 100%.
