6 - 50 Quick Check® SV Series User’s Guide

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.

LED Operation

1. LED1 will turn on when Port 3 is active due to ISO, Symbol Contrast, X

dimension, ratio, mod check or quiet zone error conditions.

2. LED1 will flash when Port 3 is active due to a data increment or decrement

error condition.

3. LED2 will turn on when Port 3 is active due to a partial, % decode or no read

error conditions.

4. LED2 will flash when Port 3 is active due to a Data Match error condition.

5. Flashing indication will override a solid on indication if both types of error

conditions occur.

Note: Both LEDs can be on in cases where multiple bar codes are analyzed in

a sync period.

SV Commands Important for Mode 19

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.

~LV19

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

~LQ0

This command disables partial decodes to activate output ports.

~LAxx

This command sets the passing threshold for the Overall ISO method Symbol

Grade. For example: ~LA28 causes an Overall Symbol Grade of 2.7 or lower

calculated for the code analyzed to set a failure condition for this parameter.
