Replacement Note: Match the complete part number 333523, hardware revision, connector arrangement and software/system configuration before installation. The RDI-32XE should not be substituted with the RDI-32Axe simply because the two modules have similar names; the manufacturer specifies different input signal characteristics for these versions.
