QTERM-G70 Terminal Terminal Components
Qlarity-Based Terminal Hardware 9
1.3.4 Speaker
A speaker is built into the QTERM-G70 terminal and faces to the back of the unit. Audio can
be linked to events or actions (e.g., screen press, timer, etc.). Pitch and duration of a sound are
controlled by API functions called from the user application. Refer to “Controlling the
Speaker” section in the Qlarity-based Terminal Programmer's Reference Manual.
Optionally, an audio (.wav) decoder can be added to the QTERM-G70 to allow the speaker to
play audio 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.
The audio decoder circuit amplifies the signal to 0.5 W rms at the speaker.
1.3.5 Real-Time Clock
The QTERM-G70 terminal is equipped with 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.
1.3.6 System Memory
The QTERM-G70 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 megabytes of flash memory and sixteen megabytes of RAM memory are standard.
For information on using resources efficiently to conserve memory when creating a user appli-
cation, refer to “Edit Resources” section in the Qlarity Foundry User Guide.

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 (CR1220) or equivalent type as recom-
mended by the manufacturer. Dispose of used batteries according to the manufacturer’s
instructions.
