c.Overall ISO Grade (Programmable, ~LAxx)
d.Bad quiet zone (~PB816xxx000)
e.No Read (if sync is received)
f.Partial decodes and % decode logic programmable (~Lp#, ~Lq#)
g.Number of codes per sync programmable (~LN##, ~LZ##)
h.Symbology modulo check digit
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.
5.Ports 1 and 3 will go high (no current) within 12.5 milliseconds after the sync input goes high (leading edge).
6.Use ~PR0200 for proper port initialization.
Mode 02 LED Operation
1.LED1 will turn on if Port 3 goes active due to ISO or quiet zone failures
2.LED2 will turn on if Port 3 goes active due to a no read or partial condition
3.The leading edge of a sync input will turn LEDS 1 and 2 OFF.
SV Commands Important to Mode 02
This system is operating in a “mode” rather than fully programmable logic. The port activation parameters are programmable via the ~PB8 rather than ~PB1, ~PB2, etc. for each individual port. Other commands, such as mode commands are also available. The commands most useful for this system application are described below.
~LV02
This command sets this mode of operation.
~Lp0
This command turns off all partial decode logic at the decoder level
~Lp1
This command turns on partial decode logic at the decoder level
~LQ1
This command allows partial decodes to activate the output ports
