Modes
Overview
Ranger supports 4 different ranging modes, those being 15° FOV, 20° FOV, 27° FOV, & DETECT modes.
FOV Modes
In the different FOV modes Ranger outputs an analog signal. Each FOV has a different update rate, and is better suited for a different distance, in general, the larger the FOV, the longer the max distance you can detect, but the slower the output is updated.
You should experiment with each mode to determine which best suits your needs, there is no one-size-fits-all solution. See Technical Data for more information.
DETECT Mode
In DETECT Mode Ranger outputs a digital signal. Ranger will send an active high signal, by default, if it detects any object within its ranging distance. The user is able to configure both a minimum and maximum threshold for this distance. This allows for Ranger to only send an active high signal for a very small target area.
Configuration Sequence
DO NOT power off Ranger during the configuration sequence.
To configure the minimum or maximum threshold values, follow these steps:
Both switches must be in the 1 position
Bring one of the switches to the 0 position
Ranging sequence will begin
Bringing the left switch to the 0 position will change the minimum threshold.
Bringing the right switch to the 0 position will change the maximum threshold.
The ranging sequence proceeds as follows:
Wait 5 seconds
Take measurement samples
Average the samples
Determine if the measurement was ok
If the measurement was ok, write to memory, otherwise ignore
If the sampled measurement is determined to be bad, Ranger will disregard the measurement and alert you with an LED pattern, find more info about the LED patterns here.
