External audio is connected to RAE-5 through system connector’s XMIC and
XEAR lines.
XEAR lines.
Serial connection channels in RAE-5 include IrDA, MBUS, and serial port.
MBUS and serial port have logic level signals which are connected through sys-
tem connector. IR transceiver is next to the system connector at the bottom end
of RAE-5 device.
