  • Page 32: Step 6. Connect The Mxibus Cable

    There are two basic types of MXIbus cables. MXIbus cables can have either a single connector on each end, or a single connector on one cable end and a double connector on the other end. Your VXI-AT2023 kit comes standard with a cable with single connectors on each end. Nonpolarized Cables The cable with a single connector on each cable end is nonpolarized, meaning that you can connect either end to either device.
