Three standard 1746 I/O assemblies with a variety of commonly used I/O
modules already installed are available for the 9/Series CNC. These
assemblies come with the I/O cards you need, and a 1746I module to
interface to the 9/Series I/O ring. For more details on 1746 I/O refer to
page 10A-49. If you did not purchase one of these preconfigured
