Powering On the Terminal for the First Time QTERM-G58 Terminal

Qlarity-Based Terminal Hardware
Library contains objects to indicate the current charge level of the battery, power source (exter-
nal or battery), and other information. Refer to the Qlarity Foundry documentation for details.
Power (8 to 32 VDC) may be connected to the G58 terminal at any time. When external power
is detected, the terminal will use external power instead of the battery for operation.
The internal battery is charged by connecting a 12 VDC supply and ground to the power pins
of the terminal. Beijer Electronics offers charging cable accessories for standard AC mains
power (with optional international plug kit) and a vehicle cigarette lighter adapter. If the termi-
nal is powered off at connection, the power and shift LEDs on the keypad will light, and the
display will show a battery charging icon. The icon and shift LED will flash during charging.
A continuously lit shift LED and static battery icon on the display indicate that charging is
complete. If the unit is powered on when the charge power supply is connected, the application
can detect and indicate charge status if desired.
5.4.2 Accessing The Internal Mass Storage Via USB
The QTERM-G58 includes internal NAND flash for mass storage. This storage memory is
accessible from both the application and the USB device interface, where it appears as a
FAT-formatted file system to the USB host.
To access the internal mass storage via USB, connect the terminal to a PC or other USB host
using the QTERM-G58 Programming Cable accessory. The USB host will enumerate the ter-
minal, which should appear as a removable disk mounted to the host’s file system. The file sys-
tem may take several seconds to become available for viewing or modification. Files may be
stored or retrieved using file access software on the PC, as with any USB mass storage device.
Note that many operating systems recommend or require that a USB removable disk be ejected
before it is removed. See the documentation for your PC operating system for more details.

The QTERM-G58 terminal is a self-powered USB device and draws negligible power from the
USB bus. Battery drain is comparable to untethered operation.
