4.5 Connect External Signals (Ribbon Housing)
For best grounding, the VST
X
ribbon cable should be connected to an interface that terminates all the
signals. (Do not attempt to split the cable or use multiple connectors on the end of the ribbon).
To terminate the VST
X
ribbon cable, you may use an interface board which is available from IMT, or
the following connector: Hirose Electronics Model Number FH33-26s-0.6sh(10)
When planning your system grounding scheme, provide both power and ground to the VST
X
ribbon
cable from a PCB mounted connector. Follow appropriate grounding methods in your system to
facilitate good EMC, including use of a single point of origin for grounds.
See Section 5 “Operation” for additional detail on the ribbon cable pins and their usage.
