4.3.2 Explanation of Direct Control Commands
The following describe direct control commands in details.
Read operation control
This command specifies the data read timing.
[LON] Trigger on
Command: LON
Response: None
[LOFF] Trigger off
Command: LOFF
Response: None
• Even when the read operation is controlled with these commands, the BL-180
performs the same operation as with the trigger input (see page 10 to 12).
• “Trigger input: on” corresponds to LON , and “trigger input: off” corresponds to
LOFF .
• The BL-180 starts read operation on receipt of LON and stops it on receipt of
LOFF .
• When a bar code can be correctly read and the read data has already been
set, you need not send LOFF .
• The command characters can be freely changed (within 8 characters).

[TEST1] Reading rate check
Command: TEST1
Response: None
[TEST2] Tact check

[QUIT] Resetting test
