Length Threshold A

Response Format:
$A
Set
is an integer specifying the number of User Scaleable Pulses for Length Threshold A.
The Length Threshold A output will be asserted when this number of pulses has been
output, and will be reset when the Index Pulse triggers. This output can be used to perform
some operation prior to a cut.
Range: 0 to 999,999,999
Example:
Assume that the User Scaleable Pulse Rate (configurable with the P command) has been
set to 1000 pulses/foot, and Index Pulse is configured to output every 200 ft.
To assert the Length Threshold A output after 180 ft:
!
= User Scaleable Pulse Rate (pulses/ft) x Length Threshold A setting (ft)
!
= (1,000 pulses/ft) x 180 ft = 180,000 pulses
The command to set the correct value is $A180000
The output will clear when the length reaches 200ft, and the Index Pulse triggers. See the
Index Pulse & Length Thresholds section for timing details.

Length Threshold B

Response Format:
$B
Set
is an integer specifying the number of User Scaleable Pulses for Length Threshold B.
The Length Threshold B output will be asserted when this number of pulses has been
output, and will be reset when the Index Pulse triggers. This output can be used to perform
some operation prior to a cut.
Range: 0 to 999,999,999
Example:
Assume that the User Scaleable Pulse Rate (configurable with the P command) has been
set to 1000 pulses/foot, and Index Pulse is configured to output every 200 ft.
To assert the Length Threshold B output after 190 ft:
!
= User Scaleable Pulse Rate (pulses/ft) x Length Threshold A setting (ft)
!
= (1,000 pulses/ft) x 190 ft = 190,000 pulses
The command to set the correct value is $B190000
