Quick Check® SV Series User’s Guide 6 - 15~LQ#Enable or Disable Port Activations by Partial Decodes~LR#Enable or Disable No Read Transmission or Alternate Data Transmission FormatsA No Read transmission message can be sent via the serial port if the SV unit isreceiving sync inputs. See "Serial Port Transmission Format" on page 3-1 fordetails. Fields y, M and N (data positions 52 through 55) set to 0, indicate a NoRead condition.Values for # are:The transmission is available in any output interface mode that includes a noread condition. The transmission data format enabled (~OS#) does not affect theformat 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 willcause a "normal" transmission if a bar code is in the laser beam when thecommand is received. This allows bar codes to be reported to ScanView duringsetup. 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 fieldused to indicate all quality parameters. The data has no framing. The data formatis 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 ofverification analyses if a bar code is in the laser beam when the command isreceived. This allows bar codes to be reported to ScanView during setup. A NoRead transmission is not available with this setting.# = 4, is identical to ~LR3 with the exception that after the data characters acarriage 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 dataonly in the format set by the ~OS# command. The data is framed by charactersset by the ~SSbbbeee command. Commands ~SA and ~SY will allowtransmission of the "normal" format including the 88 byte field of verificationanalyses, but the transmission will also be framed with the characters set by the~SSbbbeee command. Therefore it may not be compatible with setup withScanView. A No Read transmission is not available with this setting.0 Disable Port Activation by Partial Decodes1 Enable Port Activation by Partial Decodes1 enables the No Read message to be transmitted0 disables the No Read transmission
