DMM Connector

Central site versions of the Excalibur Multirate DAP have an additional connector,

labeled DMM, that is not provided on standalone units. This connector is typically used

in central site applications to daisy-chain the CMS system diagnostic channel. Use Cable

Part No. 5956-849U to connect the DMM connector on the first unit to the NMI

connector on the next unit. Continue to daisy-chain units in the same manner: DMM to

NMI.
