Analog inputs
The MobileView PENTA DVR lets you monitor two analog signal inputs. Analog
inputs are generally used to measure such things as pressure, temperature, and
velocity. These variables are commonly available on heavy-duty vehicles. Once
these are converted to electrical inputs in the ranges of 0 to 30 V, the DVR can
monitor and act upon them.
The value directly under each bar is the digital value between 1 and 255 of each
analog input. The digital value is necessary to create an event based on an
analog input.
To determine digital values for analog input conditions:
1. Change the state of the analog input to the condition under evaluation.
2. Record the input value at that condition.
3. Repeat steps 1 and 2 for each condition.
4. Repeat steps 1 through 3 for each input.
