Installation
Alternative Installation Options
In addition to Plug-n-Play installation
flexible design accommodates several additional installation options.
One-wire Connect via "Floppy-disk" extension cable
If mounting the navX-MXP circuit board directly into the RoboRIO's onboard MXP connector is
not possible, a "Floppy-disk" extension cable can be used to place the navX-MXP circuit board
up to a few feet away from the RoboRIO. This installation method supports the I/O expansion
capabilities, since all MXP connector signals are carried over the extension cable.
Note that higher-speed signals such as those found on the SPI and I2C bus, and noise-
sensitive analog signals like those on the Analog Input and Output pins may be negatively
impacted by longer distances and electro-magnetic interference, so high quality shielded cabling
and shorter distances may be called for.
These extension cables are available online at AndyMark:

One-wire Connect via USB cable
By using a USB Mini-B type (Male) to USB A type (Male) connector, navX-MXP can receive
both power and also communicate with the RoboRIO.
This installation method allows the navX-MXP circuit board to be placed longer distances away
from the RoboRIO than via the "Floppy-disk" extension cable method. However, this installation
method does support the I/O expansion capabilities, since the MXP connector signals are not
routed over the USB cable.
