Wille the LV-MaxSonar-EZ1 range finder interfere with other sonar range finders?

it's 2.5 - 5.5V.

The DI/O connections provide 5V on the center (Red) wire.

A bit more research... The sonar sensor gets wired to one of the analog channels on the NI 9201. Each channel has 3 terminals, 5V, Gnd, Analog IN. Follow the LV MaxSonar pin out connections for the connections to the sonar sensor. Thanks team 122 for this info.

The EZ1 can also be wired to run in a DIO slot, which is what I've done with mine.

Ok, thanks. Guess it depends on code you plan on using, analog channel or digital.

We are using a 555 timer in astable mode to synchronize the ranging of multiple detectors (alternative solution to chaining). You can use DIO to the reset line of the 555 timer to control when the sonar ranges, or allow it to free range at the interval of the 555 timer. We have the 555 timer set to range a little slower than the default rate. Hopefully that will minimize interference with other bots.

We also found the voltage from the Analog board is noisy enough to affect the accuracy of the sensor. Used the capacitor/resistor circuit in the faq to stabilize the power.

One connector from the board to the sonar solves both problems.

How do you use the DIO with the sonar? seems like you would have to use the serial connection, and that is only good for 1 sensor.
