• Parameters
VERSION NUMBER (0 to 65535)
Allows the user to assign a “version number” for tracking and referencing different setup
files.
FILE TYPE (User defined)
Allows the user to assign a “file- type” name for tracking and referencing different
setups.
TI GAIN (0-8)
Sets the maximum gain/amplification level that is applied to the return signals on all of the
Front-End circuits. The “Front-Ends” are the circuits that control the transducers. A TI
gain setting of 2 is recommended for most applications.
DIGITAL POT GAIN (40-200)
Sets the gain/amplification level for each of the six Front-End circuits within the limits of
the IT GAIN setting. NOTE: The TI gain together with the digital pot gain controls the
sensitivity of the AGV-1000.
BLANKING (0.229 meters Min.)
Sets the length of the dead zone in front of the transducers. Echo returns from inside the
blanking zone will be ignored. DO NOT set the blanking distance lower than the 0.229
meter minimum! Shorter blanking settings are used for testing purposes only.
PULSES (16-30)
Sets the number of pulse waves sent in each ultrasonic burst. This setting controls the
strength of the transmit signals.
SAMPLE RATE (80-250 msec)
Sets the delay between samples taken by the AGV-1000. A shorter delay will allow for
quicker detection of an obstacle
FAULTS (4-250)
Sets the number of transducer “short” or “open” circuit readings before the sensor
outputs an error condition. The faults are input to an “up-down” counter. For example,
suppose the faults parameter is set to 10. If 8 consecutive transducer “short circuit”
readings are taken, then the counter would increase to 8. If the sensor then receives 5
consecutive error free readings, then the counter would count down to 3. If the sensor
