• 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
