1-3. System Indicator and Status Indicator

1-3-1. System Indicator

The system indicator mainly indicates the operation status of the hardware. The system indicator lights in red when the power is turned on. Generally it changes to amber soon, and then to green when the system normally starts. If not, the indicator blinks in green or amber. In this case, the system file needs to be reinstalled using the boot-up MMC (MultiMediaCard). (Refer to Section 1-9.)

Color of light Functions of indicator System operation/status

Red (lights) Lights on immediately after startup. Resetting hardware, etc.

Amber (lights) Indicates that the CPU started. Downloading Configuration data to FPGA

Green (lights) Indicates that the operation software started. Startup screen is displayed. Green (blinks) Indicates that although the download of

Amber (blinks) Indicates that the download of Configuration data is

The indicator stays lit in red if there is no boot program such as the case that nothing is written in the flash memory.

The indicator changes to green when the (approx. 7 seconds) download of Configuration data to FPGA is completed. In case that the indicator stays lit in amber, it means that a configuration error (Configuration file is not normal, etc.) has occurred.

Configuration data is completed, an error was detected in the initial check of FPGA.

failed and the UCP-8060 cannot start due to an error.

1-3-2. Status Indicator

The functions of status indicator at the power-on/restart are different from those when the Memory Stick is used.

At the power-on/restart

The UCP-8060 checks the file of operation software installed and indicates the results with the status indicator.

. Amber (blinks)

Indicates that the status error related to the software is detected. The status indicator blinks in amber when the UCP-8060 cannot start in such case that the system file is damaged although the CPU is not damaged. At the same time, the system indicator lights in red or amber, or blinks in amber. The number of blinking varies depending on the type of error. In any case, install the system file again. (Refer to the operation manual.)

The system file is checked before FPGA starts. Therefore the indication at the power-on /restart is not mixed up with the status indication when the Memory Stick is used.

. Amber (Continuously blinks)

Indicates that FPGA is not normal. The system indicator blinks in amber at the same time. If FPGA is not normal, the LCD module cannot be controlled. Therefore the system cannot start. In this case, the system automatically tries to start the BIOS UTILITY after continuously blinking in amber for ten times. If the BIOS UTILITY can be started, the communication via RS-232C is enabled.
