Mode 19 (~Lv19) - Hand Held Products SV Series User Manual

~Hx
This command stores all parameters into non-volatile memory. This command
should be the last command sent after parameters are programmed via the
above commands.

Mode 19 (~LV19)

I/O operation
1. Envelope type sync input on pin 4
2. Port 3: per sync type. The state of this output must be stable within 12.5
milliseconds after the sync input goes low (trailing edge.) Typical time for
stability will be less than 7.5 milliseconds if the sync is received when a bar
code or complex graphic is not in the beam. The port shall go active (sink
current) 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 error
m. 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 minimum
4. Port 1; acts as strobe (signal ensuring Port 3 condition is stable) in response
to trailing edge of sync input. This signal will go "on" (sink current) between
20 and 100 microseconds after Port 3 condition is stable.
