Hx19tr is a very high speed, high precision ultrasonic positioning system, with a significantly improved range up to 35 meters and 5mm precision (25khz sensor). Maximum sampling rate is 64 samples/second and the system can be multi-layer, frequency separation multiplies the positioning frame rate. Using 2 frequency layers 25khz and 40khz enables a total acquisition of 128 (xyz) coordinate points per second. The device on the right is a hx19tr40khz-USB it has an internal FDTI USB controller, drivers are available for many operating systems.

The hx19tr is designed to serve many positioning needs, and serves equally well for guidance and tracking. Each hx19tr is a transponder, useful as both a transmitter and a receiver. It also times its own echo, adding anti-collision features to the system; while providing the distance from itself to any other active members of the hx19 family.
The HX19TR Serial Wire

The hx19tr comes with a four conductor pigtail lead, red, blue, green and black. Red and Green are the power wires, where Green is the reference (ground), and the red provides the supply voltage ranging from 4V to 16Vdc. Yellow and Orange are used as communication signal carriers. All hx19tr types have a wire interface, or may be terminated with a USB plug for computers. Some hx19tr devices will have additional RF wireless  interface. The wireless units synchronize communities of hx19tr devices, and provide data-link between networks as well as individual devices. What is received by wireless communication is repeated on the wire, and what comes over the wire is repeated by RF wireless broadcast. The same applies to the USB version.

Difference between the hx19tr and other hx19 members. 

The hx19tr, is server to wireless network or wired network. It repeats incoming data on the wire through wireless broadcast and vice versa. Operation is simplex, i.e. the device must wait for transmission to finish before sending a reply. It simplifies wiring by allowing communication through a single wire, and a ground return, or long-range rs485 communications. It is self-sufficient needs no support and has echo mode embedded into its positioning cycle.
