THE 8570 KEYBOARD
B.1 Keyboard Features
The 8570 Keyboard (PN 31612) is an external DB9 QWERTY keyboard, designed
specifically for mobile computing applications. It is rugged and sealed to resist
water, dust, shock and vibration. Designed for in-vehicle or harsh environment use,
it is rated Nema 4. The DB9 cable is connected to the 8570 through the cable gasket.
For detailed keyboard specifications, please see page 85.
A PS/2 version (PN 31612-001) of the same keyboard is also available. This version
is necessary if the keyboard and a scanner are to be used. The PS/2 keyboard
requires the keyboard/mouse “Y” cable, PN 31617, which has a DB9 male
connector at one end and two PS/2 connectors at the other. The DB9 connector of
the cable connects to the 8570 through the cable gasket, but the PS/2 connectors are
outside the gasket, providing for easy attachment and detachment of the keyboard.
Note: When the keyboard is attached to the 8570, the touch screen will
still operate.
The keyboard is Windows 98/NT-compatible and has 86 keys, with 101-key
functionality. To create a touch-type feel, the 8570 Keyboard uses keyswitches to
provide mechanical tactile feedback. There are embedded LED indicators for scroll
lock, num lock, and caps lock keys, as well as a16-key numeric keypad, Windows
98 keys, a Macro key, and a function lock key. The 8570 Keyboard features a three-
button integrated HulaPoint pointing device. The pointing device offers a high level
of accuracy and a user-friendly interface. The HulaPoint is totally sealed, which
prevents dirt and other contaminants from causing malfunctions.
This backlit keyboard has four levels of brightness control (including “Off”),
making it practical for low-light environments. The backlighting is powered through
green LED's and is activated with a single key, identified on the keyboard with a
light bulb icon (see Figure B.2 on page B-3).
