•
The number of digits of the data is stored in the +05 address.
•
The read bar code data is stored in the A+06 to A+69 addresses using the
ASCII codes (hexadecimal numbers in two digits) by the digit.
➮ See the ASCII code table on page 169.
•
If a read error occurs, the “ERROR” code is stored in the corresponding area.
(The reading error code can be easily changed in the BL-600 settings.)
➮ See page 43.
•
If a buffer overflow error occurs with the BL-600, the “OVER” code is stored in
the corresponding area.
•
If an error occurs in the main unit, the “MOTOR” code is stored in the corre-
sponding area.
Note 1: When test mode is enabled, the BL-600 does not write data.
Note 2: These data areas accept up to 64 digits. However, the BL-600 can read
only 32 digits. When the bar code type is CODE128 and the start character is
CODE-C, up to 64 digits can be read.
