BoltGATE 20-25 User Manual Rev. 1-1 6 Front Side Overview
6.6.2.3 MVB EMD Connection Notes
To use the with MVB EMD segments, apply the following terminations on the 9-Pin D-Sub connectors:
Figure 6.1 - MVB terminations on the Female 9-Pin D-Sub Connector
Figure 6.2 - MVB terminations on the Male 9-Pin D-Sub Connector
The appropriate pins from the MVB line are connected to the local terminating resistor within the MVB
board . The effective line termination matches the recommended cable impedance of 120Ω.
Assuming that the BoltGATE 20-25 is the last of several MVB nodes, one of the MVB connectors remains
free. The terminator is mounted on this connector and delivers the correct line termination.
Depending on the cabling concept, it is typically required to have two types of terminators: one with a
female D-sub connector and one with a male D-sub connector.
The terminator is not included with the BoltGATE 20-25.
