Polarized Cables

If you are using a MXIbus cable with a single connector on one cable end and a double
connector on the other end, it is a polarized cable that you must install correctly for the system to
function properly. Connect the end with the single connector to the AT-MXI and the end of the
cable with the double connector to the VXI-MXI. Be sure to tighten the screw locks to ensure
proper pin connection. See Figure 2-13.

When you have properly connected the MXIbus cable, power on the VXI mainframe and then
the PC AT computer.
Note: Always turn on the mainframe first. Doing so makes it possible for the PC AT to
access the VXI cards in the mainframe as soon as the PC AT starts up.
