Precautions for Correct Use
•
Please be aware that the Multidrop Connector (DCN4-MD4) will protrude into
the adjacent panel. Provide any measures to prevent it from interfering with

In a configuration where plural 3G8F7-CRM21 CompoNet Master Boards for
PCI Bus are used, only one side of adjacent two Boards shall use a DCN4-
MD4 Multidrop Connector.
