About (From User Manual):
The HI-PRO Hearing Instrument Programming Unit in conjunction with fitting software and programming cables constitute the whole HI-PRO system. The HI-PRO hardware serves as a standardized interface between a PC and programmable hearing instruments
Connection to the PC is by way of the supplied USB (Universal Serial Bus) cable. The USB connection both establishes the electrical power and the knowledge communication between the PC and the HI-PRO.
On the cupboard front, two 6-pole mini-DIN connectors for the cables to the programmable hearing instruments facilitate programming of both a left and a right hearing instrument.
The PC sends details about the communication protocol (e.g. communication type, voltage levels, and clock frequency) and orders the HI-PRO to read from or write data to the programmable hearing instrument. The PC software for programming the hearing instrument (Fitting Software) is supplied by the hearing instrument manufacturer.
The cables for connecting hearing instruments to HI-PRO are supplied by the hearing instrument manufacturer.
The serial USB (Universal Serial Bus) port is used for communication between a PC and the HI-PRO 2 unit.
