Audio
The base unit has Sound
Higher quality integrated stereo speakers may be added as an option to the terminal. The amplifier is located on the Processor Board; the speaker output is provided on a header that receives the harness from the speaker module. In addition, a Line Out is provided on a 3.5mm stereo jack that permits connection of external amplified speakers.
The integrated stereo speakers, or an amplifier connected to Line Out, must be used in order to play Sound Blaster (audio subsystem) audio. However, an internal EUI speaker provides PC speaker functionality (beeps and tones) for all configurations.
The volume control can be set during system configuration.
The PC speaker sounds (such as beeps and touch clicks) are directed into the audio subsystem and are audible if speakers are connected.
Magnetic Stripe Reader
A
When card data is read, an interrupt is generated. A software device driver for the MSR must be loaded to enable the application to process the data.
