NI myRIO-1950 User Guide and Specifications

Safety Information

Caution

Do not operate the hardware in a manner not specified in this document 

and in the user documentation. Misuse of the hardware can result in a hazard. You 
can compromise the safety protection if the hardware is damaged in any way. If the 
hardware is damaged, return it to National Instruments for repair.

Clean the hardware with a soft, nonmetallic brush. Make sure that the hardware is completely 
dry and free from contaminants before returning it to service.

Electromagnetic Compatibility Guidelines

This product was tested and complies with the regulatory requirements and limits for 
electromagnetic compatibility (EMC) stated in the product specifications. These requirements 
and limits provide reasonable protection against harmful interference when the product is 
operated in the intended operational electromagnetic environment.

This product is intended for use in commercial locations. There is no guarantee that harmful 
interference will not occur in a particular installation or when the product is connected to a test 
object. To minimize interference with radio and television reception and prevent unacceptable 
performance degradation, install and use this product in strict accordance with the instructions 
in the product documentation.

Furthermore, any modifications to the product not expressly approved by National Instruments 
could void your authority to operate it under your local regulatory rules.

Caution

To ensure the specified EMC performance, the length of any cable 

connected to the USB ports must be no longer than 3 m (10 ft), and the length of any 
cable connected to the MXP ports must be no longer than 0.3 m (1 ft).

Caution

To ensure the specified EMC performance, do not connect the power input 

to a DC mains supply or to any supply requiring a connecting cable longer than 3 m 
(10 ft). A DC mains supply is a local DC electricity supply network in the 
infrastructure of a site or building.
