Operating modes
The LSR116 operates in one of three ways, as defined by the
AISOMD
command. Refer to the
on page 17 for a list of commands that you can send to configure the LSR116.
4.1
Mode summary
4.1.1 Dumb mode
The LSR116 is a one-way communication device.
The device detects the media and activates the imager and illumination. When the LSR116 reads
the barcode, it sends the data to the host, activates the
‘Good Read’ indicators, and disables the
imager and illumination. The imager and illumination do not reset until the LSR116 sensor fails to
detect any media for 0.5 seconds.
4.1.2 Host mode
The LSR116 is a two-way communication device that reads barcodes and waits for a host to accept
or reject the barcodes.
The device detects the media and activates the imager and illumination. When the device reads the
barcode, it sends the data to the host and disables the imager and illumination. The LSR116 waits
for a response from the host to accept or reject the data, which activates the
‘Good Read/Bad Read’
indicators on the device. The LSR116 waits for up to two seconds for an
‘Accept/Reject/Ignore’
command to activate indicators.
The host sends an ‘Ignore’ command to reset the imager if no
response from the indicators is required. The imager and illumination do not reset until the LSR116
sensor fails to detect any media for 0.5 seconds.
The ‘Ignore’ command requires version 1.0.21 (or later) of the firmware.
4.1.3 Interactive mode
Note:
This is not the recommended mode for new installations.
The LSR116 is a two-way communication device, controlled fully by a host.
The LSR116 detects the media and sends a command to the host with this information. If the media
is removed, a second command is sent telling the host that the media is no longer detected.
If the media is present, the host sends a command to activate the imager and illumination. When the
LSR116 reads the barcode, it sends data to the host. The imager and illumination are not disabled.
The LSR116 waits for a response from the host to accept or reject the data, which activates the
‘Good Read/Bad Read’ indicators and disables the imager and illumination. An ‘Ignore’ command
may also be used, although untriggering the unit is more useful in most cases.
At any time, the host can send
‘Good Read’ or Bad Read’ commands activate or deactivate the
imager and illumination.
