HandHeld Entertainment SV Series manual ~LS## Set minimum number of scans for valid read

Page 64

#= 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 ScanView 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 ScanView. With this setting, a No Read transmits the string "No Read" instead of the No Read analysis record.

~LS##

Set minimum number of scans for valid read

## = 02 – 99 (See ~SBn (page 6-24) command for ##=01; single scan mode)

This command sets the minimum number of times a full decode must be achieved on a symbol in order to be a valid read. The system acts slightly differently, depending on what operation mode is set – ~HO1 or ~HO2.

With ~HO1 enabled, if the minimum number of full decodes is not accomplished, a No Read condition is set, even though the bar code is read, analyzed and reported. The report includes a No read status indication. With ~HO2 enabled, if the minimum number of full decodes is not accomplished, the code is not recognized nor reported. This essentially creates a No Read condition when a sync input is being received.

When used in conjunction with the ~LDxx command, the ~LS## command can create a powerful area check of a symbol.
