Resolution / Answer
This setting is used to configure the communication method or communication parameters between the device and the host. Usually when connecting to a computer, serial device, RS485/Modbus network or access control Wiegand system, you need to ensure that the parameters at both ends are consistent.
China Post 25 barcode data is not forced to contain check characters. If there is a check character, it must be the last character of the data. The check character is the calculated value of all data except the check character, used to verify whether the data is correct.
u Set to "Disable", the scanner will transmit all barcode data normally.
u Set to "Enable, do not transmit check characters", the scanner will verify based on the last 1 digit of the barcode. If the verification passes, the normal data except the last digit of the check character will be transmitted. If the verification fails, the barcode content will not be sent.
u If set to "Enable, transmit check character", the scanner will verify based on the last 1 digit of the barcode. If the verification passes, the check character will be transmitted together with the last 1 digit of normal data. If the verification fails, the barcode content will not be sent.
**??rohibited??
Scan the following barcode to configure **[Prohibited].
[Enable, do not send check characters]
Scan the following barcode to configure [Enable, do not send check characters].
[Enable, transmit check characters]
Scan the following barcode to configure [Enable, transmit check characters].
When set to "Enable, do not transmit check characters", if the data length minus the 1-byte check character is less than the minimum code reading length limit, the code reading will fail.
For example: in the current scanner settings, the minimum reading length of China Post 25 is 4 bytes, and no check characters are transmitted. At this time, if you want to read China Post 25 with a total length of 4 bytes, it will fail!
