When receiving this number, the receiver will transfer the corresponding audio information to the Mollie System. Mollie then decides on the action to be taken, for example to play the audio information. The GuidePort Receiver uses a prestored assignment table for translating the numbers into the correct action. - Page 13 7, MSB Read/Write Frame Clock Interrupt_2 Reset Interrupt_1 digital ground for digital interface 3.3 volts digital power, from Mollie digital ground from Mollie analog ground from Mollie 5 volts analog power from Mollie GuidePort: System Manual 27.
