Enable or Disable No Read Transmission, or Alternate Data Transmission Formats
A No Read transmission message can be sent via the serial port if the SV unit is receiving sync inputs. See
the Serial Port Transmission Format Section for details. Fields y, M and N (data positions 52 through 55)
set to 0 indicate a No Read condition.
# = 1, enables the No Read message to be transmitted
# = 0, disables the No Read transmission.
The transmission is available in any output interface mode that includes a no read condition. The
transmission data format enabled (~OS#) does not affect the format of the No Read transmission.
Alternate data formats can also be transmitted using the ~LR# command.
# = 2, disables all data transmissions. The exceptions are ~SA and ~SY will cause a “normal” transmission
if a bar code is in the laser beam when the command is received. This allows bar codes to be reported to
ScanVision during setup. A No Read transmission is not available with this setting.
# = 3, causes the SV unit to transmit bar code data only without the 88 byte field used to indicate all quality
parameters. The data has no framing. The data format is determined by the state of the ~OS# command
(data or all symbol characters). ~SA and ~SY will cause a “normal” transmission including the 88 byte
field of verification analyses if a bar code is in the laser beam when the command is received. This allows
bar codes to be reported to ScanVision during setup. A No Read transmission is not available with this
setting.
# = 4, is identical to ~LR3 with the exception that after the data characters a carriage return character is
transmitted followed by a line feed character.
# = 5, is similar to ~LR3 in that it causes the SV Unit to transmit bar code data only in the format set by the
~OS# command. The data is framed by characters set by the ~SSbbbeee command. Commands ~SA and
~SY will allow transmission of the “normal” format including the 88 byte field of verification analyses, but
the transmission will also be framed with the characters set by the ~SSbbbeee command. Therefore it may
not be compatible with setup with ScanVision. A No Read transmission is not available with this setting.
# = 6, causes the SV unit to transmit bar code data only, without the 88 byte field used to indicate all
quality parameters. The data has no framing. The data format is determined by the state of the ~OS#
command (data or all symbol characters). ~SA and ~SY will cause a “normal” transmission including the
88 byte field of verification analyses if a bar code is in the laser beam when the command is received. This
allows bar codes to be reported to ScanVision during setup. With this setting, a No Read transmits the
string “No Read” instead of the No Read analysis record.
# = 7, is identical to ~LR3 with the exception that after the data characters a carriage return character is
transmitted followed by a line feed character. With this setting, a No Read transmits the string “ No Read”
instead of the No Read analysis record.
# = 8, is similar to ~LR3 in that it causes the SV Unit to transmit bar code data only in the format set by the
~OS# command. The data is framed by characters set by the ~SSbbbeee command. Commands ~SA and
~SY will allow transmission of the “normal” format including the 88 byte field of verification analyses, but
the transmission will also be framed with the characters set by the ~SSbbbeee command. Therefore, it may
not be compatible in setup with ScanVision. With this setting, a No Read transmits the string “No Read”
instead of the No Read analysis record.
