is an integer specifying the number of User Selectable Pulses for Length Threshold B.
The Length Threshold B output will be asserted when this number of pulses has been out-
put, and will be reset when the Index Pulse triggers. This output can be used to perform
some operation prior to a cut.
Example:
Assume that the User Selectable 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 Selectable 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<CR>
The output will clear when the length reaches 200ft, and the Index Pulse triggers. See the
112H
Index Pulse & Length Thresholds section for timing details.
H
Hour Meter Current Value
H<CR>
Read Only Command
Response Format:
<N>
This command returns the total number hours that the gauge has been running.
I
Current & Max Temperature
I<CR>
Read Only Command
Response Format:
<N>,<N>
This command returns both the current internal temperature, and the maximum tempera-
ture that has been recorded. Both temperatures are in Celsius. The values returned from
the LS8500-4 must be divided by 100 to get the temperature.
The normal temperature rise from ambient to internal is 10-15ºC.
Example:
Command:
I<CR>
Response:
3225,4538<CR>
Meaning: Internal Temperature: 32.25ºC
Maximum Internal Temperature: 45.38ºC
