NI 435XRefers to all devices in the National Instruments 4350 and 4351 families.

Unpacking the Kit

Follow the unpacking instructions below that correspond to the

NI 435Xdevice.

♦NI PCMCIA-4350

The NI PCMCIA-4350 is shipped in an antistatic vinyl package; when you

are not using the NI PCMCIA-4350, store it in the antistatic vinyl package.

Because the NI PCMCIA-4350 is enclosed in a fully shielded package,

no additional electrostatic discharge (ESD) precautions are necessary.

However, for your own safety and to protect the NI PCMCIA-4350, never

touch the connector pins.

♦NI PXI-4351 and NI PCI-4351

The NI PXI-4351 and NI PCI-4351 ship in antistatic vinyl packages that

prevent electrostatic damage to the device. ESD can damage several

components on the device. To avoid such damage when handling the

device, take the following precautions:

• Ground yourself using a grounding strap or by holding a grounded

object.

• Touch the antistatic package to a metal part on the computer chassis

before removing the device from the package.

• Remove the device from the package and inspect the device for loose

components or any other sign of damage. Notify NI if the device

appears damaged in any way. Do not install a damaged device in the

computer.

•Never touch the exposed connector pins.

•Donot touch the printed circuit board or any components on the board

because this may affect performance of the device.

Caution The NI PXI-4351 and NI PCI-4351 are ESD/contamination sensitive. Handle the

board using the edges or metal bracket.

♦NI USB-4350

The NI USB-4350 is shipped in an antistatic vinyl package; when you are

not using the NI USB-4350, store it in the antistatic vinyl package. Because

the NI USB-4350 is enclosed in a fully shielded package, no additional

Note The NI USB-4350 is only supported in Windows 2000/XP/Me/98.

You can connect the NI USB-4350 to any available USB connector that

supports high-power, bus-powered peripheral devices. The following are

general installation instructions, but consult the PC user manual or

technical reference manual for specific instructions and warnings.

1. Connect the USB cable from the computer port or from any other hub,

to the port on the NI USB-4350.

2. The computer should immediately detect the NI USB-4350. When the

computer recognizes the NI USB-4350, the LED on the front panel

blinks or lights up, depending on the state of the device.

If the LED lights up after the NI USB-4350 is connected to the host,

the NI USB-4350 is functioning properly. If the LED remains off or

blinks, refer to Table 1.
