Connecting Source and Destination Devices
A routing switcher system requires careful planning. This can include allocating common connector numbers
across several router levels or partitions within the routing switcher system to ensure that source and destination
equipment switch on just one switch command. Alternatively, the inputs and outputs can be mapped across multiple
levels using the NK-VRC Virtual Routing Core.
To connect source and destination devices to the routing switcher
1. Connect a 75

coaxial cable with BNC connectors between the source or destination device and the
appropriate input or output connector on the rear panel of the NK-3G144.
2. Ensure that the bayonet connector is locked in place correctly.

A Trompeter tool may be useful for connecting BNC connectors in a densely wired routing switcher.

Wear an earthed wrist strap if possible, or place both hands on the metal rack frame before handling the
cables.
