4.3 Command Communication
The BL-180 includes commands to directly operate the BL-180 (direct control
commands) and the commands used to change or confirm the BL-180’s settings
(parameter setting commands).
4.3.1 Setup of Direct Control Commands
Communication procedure
1. Send a direct control command from the PC to the BL-180.
2. After receiving the command, the BL-180 sends back an OK response and
executes the required operation.
When the read operation control command or test mode control command is
sent to the BL-180, the BL-180 sends back no response.
3. When an incorrect command is sent to the BL-180, the BL-180 sends back
no response.
LF can be added after the command being sent. In this case, however, LF is not
added to the response data.
When ESC is inserted 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
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.
