7.3.1. Focal Plane
The optical performance of the scanner is the highest when the focal plane is
located 31.4 mm from the edge of the scanner. Therefore, set objective barcodes
at about 31.4 mm from the scanner.
This is helpful especially when scanning a barcode with high resolution or low
PCS.
It is possible to scan barcodes up to 80 mm wide when the barcode is located on
the focal plane.

Conditions
When scanning barcodes 80 mm wide or barcodes 60 mm and wider with low PCS
and curvature, scanning performance is guaranteed only when they are scanned at
the focal point.

7.6. Scanning Barcodes on Moving Items
Scanning barcodes on moving objects requires that the speed of the barcode be adjusted
to optimize the scanner’s reading performance. The orientation of the barcode is another
consideration and plays an important part in determining the speed.
The barcode label can be oriented horizontally (ladder) and vertically (picket-fence). The
scanner’s reading performance is improved when barcodes are moving vertically (see
Figure 9).
Scanning performance may differ depending on the moving speed of the barcode. The
achievable label speed can be calculated and depends on the following input values:
•Scan speed = 200 scans/s
•Redundancy = minimum 3 scans per label, plus the redundancy as set by user
•Label height
•Label speed
The label height and speed influence each other. It is necessary to keep enough height
between barcodes.
Figure 9: Barcode moving vertically
However, when scanning barcodes that are moving horizontally, the optical capabilities of
the scanner are reduced (see Figure 10). Therefore, be sure to stop the barcode for
about 200 ms when the barcode is aligned with the center of the scanner.
Figure 10: Barcode moving horizontally
When scanning barcodes on moving items as described above, scanning performance
may decline rapidly, depending on operating conditions.

The scanner and the host computer notify each other of their state and
whether they can receive data with BUSY/READY through an RS line.
They can communicate state to each other through a CS line when
connected as in the following figure.

The scanner stays ON (is able to receive data) except during certain parts
of the process, such as receiving data (buzzer command execution),
transmitting data, and menu processing. The scanner checks the CTS line
before transmitting data. When it is ON, the scanner transmits data. When
it is OFF, the scanner waits for it to turn ON within a set time. The scanner
will abort transmission with an error indication (buzzer) when the CTS line
is not ON within a specified period. The Flow Control time-outs are as
follows, and the default setting is “indefinitely“ (I0).

CS, SD signal timing
When the CS line (RTS signal of the host) is turned OFF while sending an SD signal,
the scanner transmits one character and waits. When the CS signal is turned ON
while transmitting a character, the character will be transmitted.

Note: When using loopback (wire connection) for RTS, CTS line of the scanner in this
setting, No handshake is not enabled.
