Explanation of Direct Control Commands
The following describe direct control commands in details.
● Trigger on
Command: LON
Response: None
● Trigger off
Command: LOFF
Response: None
•
Even when the read operation is controlled with these commands, the BL-700
performs the same operation as with the trigger input (
➮ see P.30 to 36).
“Trigger input: on” corresponds to LON, and “trigger input: off” corresponds to
LOFF.
•
The BL-700 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).
● Reading rate check
Command: TEST1
Response: None
● Tact check
Command: TEST2
Response: None
● Resetting test
Command: QUIT
Response: None
•
After using the test mode, be sure to reset it.
● Turning the OK output on
Command: OKON
Response: OK
● Turning the NG output on
Command: NGON
Response: OK
● Turning the OK/NG outputs off
Command: ALLOFF
