3.5.2 Power
The 8570 Vehicle-Mount Computer can be connected to either an AC or DC power
supply, depending on whether its use is for mounting on vehicles or at fixed
locations adjacent to cross-dock doors or manufacturing stations. Power is supplied
to your 8570 computer through the power connector (see Figure 3.5 on page 31).
Note: When the 500 MHz 8570 Vehicle-Mount Computer is first supplied with
power, the unit will power up automatically. Subsequent operation is the
same as the standard 8570. If the 500 MHz unit is disconnected and then
reconnected to a power source, it will again power up automatically.
The 8570 is capable of operation from several power sources:
• Pre-regulator power module for vehicle input voltage in the range of 10 to
55 Volt DC.
• Optional pre-regulator power module (55-90 Volt DC).
• Optional universal 120/240 VAC/DC adaptor.
• Optional transient suppressor (recommended for vehicles with large
hydraulic or traction motors).
For instructions on installing power connections, see “Power Options” on page 60.
3.5.2.1 Power Button
The power button is located on the right side of the computer. Depressing this button
for approximately one second will turn the computer ON. Normally when turning
off the computer, do not use the power button. Close all applications and then
choose “Shut Down” from the Windows Start menu. If the power button is held
down for more than seven seconds, the computer will power OFF and the hardware
will reset fully.
Important: Use the Windows Shut Down function to power off the computer.
