INTERSCAN CODE DELAYS 
 
³816580
 
*  InterScan Code Delay 800 msec - The time 
specified represents the amount of time between 
individual 11 bit-scan codes.  This parameter may 
need to be adjusted for operation with certain PC 
keyboard BIOS. 
³8165750
 
InterScan Code Delay 7.5 msec - This time 
specified represents the amount of time between 
individual 9 bit-scan codes.  This parameter may 
need to be adjusted for operation with certain PC 
keyboard BIOS. 
³81651500
InterScan Code Delay 15 msec - The time 
specified represents the amount of time between 
individual 11 bit-scan codes.  This parameter may 
need to be adjusted for operation with certain PC 
keyboard BIOS. 
³916500
 
~ 
ariable InterScan Code Delay msec - Refer to 
Multi-Code Method on page 2.  Sets value in 100 
microsecond increments. 
 
 
CONTROL SETS 
 
In general, standard bar code symbologies will only encode the ASCII character 
set.  Function keys, arrow keys and many other extended keys on an IBM 
compatible keyboard do not translate to ASCII characters.  One method of ‘bar 
coding’ the extended keys is to substitute the extended key codes when a 
specific ASCII control character is found in the bar code stream.  The Control 
Sets are specific translations of the ASCII (HEX) set.
