The hx17 is a successor to the hx5 and hx11 systems. Designed for tracking operations only, it is simple and easy to apply. It comes with comprehensive software packages, utilizing visual basic as a fast track to help reduce the interval between project initiation and commercialization.

The Hexamite positioning systems are not ping systems, they all read the character content of the ultrasonic signal and can therefore tell thousands of transmitters apart. Actions like clapping hands can created high volume spikes in the ultrasonic range that will demolish the simple ping. Hexamite systems have high immunity to such spikes and disturbances, and can recognize a specific signal in a jungle of echoes.

(for 3D (x,y,z) operation the overhead receivers cannot all be in the same plane)

Hexamite offers two types of controllers as illustrated above, one with a straight ASCII serial port (RS232) interface, this controller HX17BAB computes the position of the tags based on difference in time of flight and transmits the result through a serial port.

The other option for the controller, is a HX17nr network reader. This device synchronizes and delivers the Id and timing data to a PC, the PC computes the positions based on the time deviation. It stores the result on a file and distributes real time data through direct data exchange (DDE), for other applications.

The HX17 network

Three basic components are used to form a HX17 network, i.e. ultrasonic receivers hx17rx, ultrasonic tags hx17tx and a network reader hx17nr. The HX17nr synchronizes the network and collects tag IDs plus time of flight of the ultrasonic signal. This data is transmitted to a readout device like the PC through a USB port. Programs shipped with the system on a CD compute and store the tags position, these also make refined real time data available to the programmer via DDE software interface. The DDE data string contains the tags ID, XYZ position in millimeters, time stamp, record number and which receivers detected the ultrasonic ID from the tag.  Hexamite provides a flat 2d viewing program for demonstration purposes.
