What are the features of the Board URM04 v2.0 Ultrasonic Sensor (ultrasonic range finder) ?

Good time of day.
I'm primarily interested in what type of signal is used? Simple or complex? And if you have a complex, you want to know his view and the occupied frequency band. Also interested in the possibility of recording a received signal, for subsequent spectral processing. If anyone has worked with this scheme I would be glad for any advice and tips in the first place the advice associated with a connection of this Board and the PC.

PS are There similar Board with more range?

On the website of the manufacturer's performance. Including the Protocol of communication.
Connect to PC via USB-RS485 (industrial, homemade).

Signal frequency is 40kHz. The principle of operation is described, other similar sensors:

"Burn" most likely without perepiski scheme will not work — as the "inside" of the ultrasonic sensors do not go to the controller directly.
