The top of the NOAHlink unit contains two connectors (6-pole
mini-DIN) for the cables to the programmable hearing instruments
(or remote control). This allows both a left and a right hearing
instrument to be programmed simultaneously.
The PC sends information about the communication protocol (for
example, communication type, voltage levels, clock frequency, etc.)
to NOAHlink, and asks NOAHlink to read data from, or write data
to, the programmable hearing instrument. The PC software for
programming the hearing instrument is made by the hearing
instrument manufacturer.
The cables for connecting hearing instruments to NOAHlink are
supplied by the hearing instrument manufacturer.
