DAQ Board Accessories Rack-Mount Kit
This guide describes how to assemble the rack-mount hardware for the AMUX-64T analog
multiplexer board and the SC-205X, SC-206X, SC-207X, and BNC-208X Series signal
conditioning boards in a standard 19-in. rack-mount cabinet.
Introduction
There are four versions of the rack-mount kit—single- and double-height kits with an acrylic
plastic cover, and single- and double-height kits with a metal wraparound cover. The metal
wraparound cover kits are ideal for high-voltage applications. However, we do not recommend
the metal wraparound cover kits for use with the BNC-208X Series boards.
