Caution To ensure the specified EMC performance, you must use an isolated cable
with the RS-485 serial port, such as NI part number 184428-01.
Caution To ensure the specified EMC performance, the length of any cable
connected to the video, USB host ports, and V2 ports must be no longer than 3 m
(10 ft). The length of any cable connected to the RS-232 and RS-485 ports must be
no longer than 30 m (100 ft).
Caution The USB device port is intended only for use in device configuration,
application deployment, debug, and maintenance.
Caution To ensure the specified EMC performance, product installation requires
either special considerations or user-installed, add-on devices. Refer to the following
sections for more information.

Special Conditions for Marine Applications
Some products are Lloyd’s Register (LR) Type Approved for marine (shipboard) applications.
To verify Lloyd’s Register certification for a product, visit ni.com/certification and search for
the LR certificate, or look for the Lloyd’s Register mark on the product.
Caution In order to meet the EMC requirements for marine applications, install the
product in a shielded enclosure with shielded and/or filtered power and input/output
ports. In addition, take precautions when designing, selecting, and installing
measurement probes and cables to ensure that the desired EMC performance is
attained.
