    1.4 How it works • Status LED The status LED lights up either GREEN or RED depending on the operation: - GREEN light indicates the completion of successful decoding of a symbol. - Flashing GREEN light indicates the image data transmission in progress. - RED light indicates the failure of decoding.

  • Page 12: Operation

    2. Operation 2.1 Basic Operation (1) When the power is turned on, LED A, B, C and D turn on simultaneously. After all of them turn off, only LED B start blinking. (2) Then two aiming beam indicate where the unit is seeing, where is the center of field of view. (3) When SYNC is on, the TFIR captures an image and starts decoding the symbol.

    7.Troubleshooting 7.1 The unit does not work while pushing the read trigger switch. Is power supply voltage within specification? Power supply voltage should be DC 3V-6V. If the DC voltage is not within the specified range not only the unit will not operate, but there is a strong possibility of damaging the unit. Is power supply polarity correct? When it is connected with reverse polarity, the unit does not operate.

  • Page 69: Is The Reading Window Clean

    To avoid this, put the scanner in angle relative to the symbol. Is the reading window clean? If the window becomes dirty or stained, the image taken by the reader might not be good enough for reading. Clean with a lens cleaner or similar anti-scratching (non-abrasive) method.

  • Page 70: The Data Does Not Transmit Or The Data Itself Is Corrupted

    7.3 The data does not transmit or the data itself is corrupted. Is the setup with host computer correct? Please check whether the baud rate and frame format is the same as that of the host computer. If frame format differs, it may seem that data is transmitted incorrectly. Do you set fixed digit for ITF In some cases, cancellation of significant digits (reading it through with a few digits than a printed digits) in ITF(Interleaved 2 of 5) might be used.
