ASCII Communication (TLx)
Default Value:
0
–
Distance Alarm Mode
When the laser is set to ASCII communication, the Logic Interface line can be
set to one of four modes using the command
TLx
:
Distance Alarm Mode
: This is the default logic output. To activate this mode
from another, use command
TL0
. The output value is 0 when the measured
distance is out of the range or selected window (see Analog Window in section
6.3).
Mutual Synchronization Mode
: Activate this mode by using command
TL1
.
Unlike with binary communication mode, the laser cannot be specifically set as
‘master’ or ‘slave’ in ASCII communication mode
, but like in binary
communication mode, synchronization mode makes it possible to synchronize
measurement sample times of two and more sensors. Synchronization is
achieved by tying together the trigger input lines of multiple sensors and also
the logic output lines of the sensor.
Hardware Zero Set Mode (Tare function)
:
Activate this mode by using
command
TL2
. When the Logic Interface wire is grounded, the currently
measured distance is assigned as the zero point and subsequent
measurements are now relative to this location within the span.
Laser Disable Mode:
Activate this mode by using command
TL3
. When the
Logic Interface wire is grounded, the laser is ON. When the switch is removed
from ground, the laser is OFF. This controls only the laser diode and not power
to the sensor itself.
