Dolphin 7200 Basics
System Features
CPU
The Dolphin's computing power is provided by a highly integrated AMD ELAN SC310 386SX 33 MHz microprocessor.
Disk Drives
The Dolphin contains two disk drives that provide storage for system files, applications, and data. A third drive is also present if
you purchase the FLASH expansion option.
Drive A Drive A contains a 120K executable FLASH EEPROM to store system utilities and to initialize the boot
process. This drive is read-only and is not usable by the developer/end-user.
Drive C Drive C is an 8MB FLASH virtual hard drive used for program and data storage. Drive C is an image
of the Drive A and not a physical drive.
Drive D If you add the expanded memory module to your Dolphin Batch terminal, it will appear as Drive D.
Eight MB of additional FLASH memory can be added via the FLASH expansion module. This option
is available in the Dolphin Batch terminal only.
Front Panel Features
This section describes features on the Dolphin's front panel. The alphanumeric and numeric Dolphins have identical back panels.
Light Emitting Diodes (LEDs)
The red LED located at the upper right corner of the LCD display is labeled SCAN. This LED illuminates when the user presses
the ON/KEY key and activates the scan engine.
The green LED located at the upper left corner of the LCD display is labeled DECODE. This LED illuminates when the bar code
software successfully decodes a bar code. Both LEDs are software programmable.
Liquid Crystal Display (LCD)
The alphanumeric, scrollable LCD consists of nine rows with 20 character positions per row and 119 x 73 graphics pixels, which
are software addressable. The electroluminescent backlight allows you to view the display in low light conditions. To conserve
power, the backlight is automatically turned off after 30 seconds. The on/off function and contrast is software programmable.
Note: The ninth row is used for system icons and application-defined icons.
Speaker
The Dolphin Batch terminal's internal speaker emits a sound level of 80dB at 10 cm.
