Performing proper grounding is very important to ensure a steady communication. Be sure grounding is done as follows:
• Comm Ports 3, 5, 6 need to be externally grounded of the communications shields, as shown in Fig. 7.
• Even when Comm Ports 2 and 4 are internally connected, grounding on the transition board needs to be done as
shown in Fig 8.
