Audio
The DuraCOR 310 supports stereo audio. Audio can be used without any modification through the HDMI
port. If audio, this includes microphone, line in, line out, and headphone, is required these signals can be
accessed using the configurable I/O pins. A cable with the P2 connector pinout below will allow the
system to breakout these signals. The second termination on the cable can be any combination of the
configurable I/O which best suits the implementation needs. See Chapter 5, section Configurable I/O
Internal Connectors for manufacturer part number, mating connector, locations and pinouts.
Caution! ESD Sensitive Components
Follow standard ESD and FOD controls to avoid damage to the internal components.
Microphone
Microphone is mono only.

Serial Configuration
The DuraCOR 310 has two integrated serial ports that are capable of RS232, RS422, and RS485. By
default, both of these serial ports are configured as RS232. The onboard microcontroller manages the
mode of the serial interfaces, and can be configured via USB. See Appendix A for more information on
configuring the serial interfaces via the onboard microcontroller.
The DuraCOR 310 also has a RS232 console port for remote communication.
GPIO
The DuraCOR 310 has support for 6x GPIO lines on the J3 connector (See Chapter 5, J3 for pins). The
signals may be configured as any combination of input or output lines. Each output drives to a 3.3V level,
inputs are 5V tolerant. See Appendix B for configuring the GPIO signals.
