SPDIF (TOSLink) Connector
The LS322 and LS422 have a SPDIF connector capable of outputting 16-bit, 48 kHz (AC3 5.1 encoded) stereo audio
streams. Muting this connector produces digital silence.
USB Host Ports
The LS322 and LS422 each have a single USB 2.0 host port capable of providing 500mA of power. Each port also
supports HID, and devices can be hot swapped without the need to reboot.
The following table illustrates the pinout of the USB host port:
pin Description pin Description
1 VBUS 2 D-
3 D+ 4 Ground
DA15 GPIO
The LS322 and LS422 have a DA15 female switch/led connector. This connector allows the player to control external
LEDs or other devices requiring 24mA of current or less.
Connect the LED outputs to the LED ANODE and connect the LED CATHODE to the ground. If you want to connect
another device, then the output is capable of sourcing or sinking up to 3.3V at 24mA, but there is a series resistor of 100Ω
in each line.
The connector also allows the connecting of external contact closures to the ground. In order to connect a switch, connect
one side of the switch to the switch input, and connect the other side to one of the ground pins on the DA15 connector.
The connector can also supply 3.3V at up to 500mA to an external device. The 3.3V output is polyfuse-protected and can
source up to 500mA.
