Terminal Components QTERM-G56 Terminal
60
Qlarity-Based Terminal Hardware
The terminal may optionally include an audio decoder that allows the terminal to play PCM
audio (.wav) files. The audio decoder supports wave files meeting the following criteria:
• Sample rate of 8 kHz, 11.025 kHz, 16 kHz or 22.050 kHz
• Resolution of 8 or 16 bits per sample.
4.3.5 Real-Time Clock
The QTERM-G56 terminal includes a battery-backed real-time clock. The real-time clock can
be used to time/date stamp messages or for timed polling and program execution.
4.3.6 System Memory
The QTERM-G56 terminal stores the firmware and user applications in a compressed format
in flash memory and then transfers them to RAM memory when the terminal is powered on.
Four MB of flash memory and 32 MB of RAM memory are standard.
For information on using resources efficiently to conserve memory when creating a user appli-
cation, refer to the “Edit Resources” section in the Qlarity Foundry User Guide.
For information on downloading new firmware, downloading a user application, and determin-
ing the size of a user application, refer to the Qlarity Foundry User Guide.
The QTERM-G56 also includes 256 MB of internal NAND flash which is accessible as a
FAT-formatted file system both from the application and the USB device port (but not simulta-
neously). Refer to section 4.4.1 for information on accessing the internal flash memory using
the USB device port.
WARNING
There may be danger of leakage if the battery is incorrectly replaced, creating a potential
health hazard. Replace the battery only with the same (CR2032) or equivalent type as recom-
mended by the manufacturer. Dispose of used batteries according to the manufacturer’s
instructions.
