Quick Check® SV Series User’s Guide 6 - 49~HxThis command stores all parameters into non-volatile memory. This commandshould be the last command sent after parameters are programmed via theabove commands.Mode 19 (~LV19)I/O operation1. Envelope type sync input on pin 42. Port 3: per sync type. The state of this output must be stable within 12.5milliseconds after the sync input goes low (trailing edge.) Typical time forstability will be less than 7.5 milliseconds if the sync is received when a barcode or complex graphic is not in the beam. The port shall go active (sinkcurrent) for the following error conditions;a. Partial Read (Programmable, ( ~Lp#, LQ#)b. % decode (Programmable, ~LD##)c. Bad Quiet Zone: < 10X (~PB816xxx100)d. ISO Defects grade (Programmable, ~PB806xxx000)e. ISO Decodability grade (Programmable, ~PB802xxx100)f. Symbol Contrast grade (Programmable, ~PB804xxx100)g. Overall ISO Grade (Programmable, ~LAxx)h. No Read (if sync is received)i. Number of codes per sync programmable (~LN##, ~LZ##)j. X dimension Range (Programmable ~PB811xxxyyy)k. Ratio (Programmable ~PB815xxx000)l. Symbology Mod Check data errorm. I 2 of 5 optional Mod 10 Check Digit data error (if enabled)n. Data Match Error (~BC)o. Increment or Decrement data error (~Br)3. Sync polarity - Leading edge high going; time between trailing (low going)edge to leading edge - 12.5 milliseconds minimum4. Port 1; acts as strobe (signal ensuring Port 3 condition is stable) in responseto trailing edge of sync input. This signal will go “on” (sink current) between20 and 100 microseconds after Port 3 condition is stable.
