Connecting a Cluster Controller Cable to a VDA Adapter

To attach a controller cluster to a VDA/128 or a VDA/255 adapter, you need a BNC
host connector, which connects to the BNC connector on your VDA/128 or VDA/255
board. Figure 4–10 shows the host connector and the location of the VDA port.

NOTE: You must connect the cluster line cable to your computer with a host
connector rather than a T-fitting.
To connect a host connector to the receptacle on the adapter board, simply push the
host connector firmly onto the receptacle, making sure that the pins on the receiving
fitting slide completely into the slots on the host connector. (See Figure 4–11.) Then
turn the knurled ring on the connector clockwise until the pins on the receiving
connector snap into place.
