4.3.3 Details on Parameter Setting Commands
The following describes how to change the BL-180’s settings through command
communication.
You can use the setup software to change the BL-180’s settings instead of these
commands.
Communication Details
1. Send the direct control command SSET to the BL-180.
The BL-180 will shift to setting mode.
After successfully executing the command, the BL-180 sends back an
OK .
2. After the BL-180 shifts to setting mode, send the command (setting change
command) corresponding to the item to be changed to the BL-180.
After successfully executing the command, the BL-180 sends back an
OK .
If an error occurs with this command, the BL-180 sends back ERR
nn
. (nn
sttands for error code numbers.)
3. To confirm the current settings, send a setting confirmation command.
After successfully executing the command, the BL-180 sends back an OK .
If an error occurs with this command, the BL-180 sends back ERR
nn
.
4. To save the current settings in the EEP-ROM, send SAVE to the BL-180.
Once you save the settings in the EEP-ROM, the BL-180 will start with these
settings when the BL-180 is turned on next.
After successfully executing the command, the BL-180 sends back an
OK .
If an error occurs with this command, the BL-180 sends back ERR
nn
.
5. To quit the setting mode and perform the normal bar code reading, send
SEND to the BL-180.
After successfully executing the command, the BL-180 sends back an OK .
If an error occurs with this command, the BL-180 sends back ERR
nn
.
Note [LF] can be added at the end of the command being sent. In this case, however,
[LF] is not added to the response data.
When [ESC] is added before the command being sent, characters in the BL-180’s
command receiving buffer are cleared.
If the BL-180’s command receiving buffer contains erroneous characters due to a
data transmission error during communication, add [ESC] to the command being
sent.
For command communication, set the time duration between transmission of
each character (byte) to up to 30 seconds. If this duration exceeds 30 seconds,
the BL-180 cancels the received characters. Note
