A
A typical VPR-5 camera interface (type NV-ICP).

Because each camera manufacturer had different connector and
interconection arrangements; Sony one type, Panasonic another,
Ikegami another (things never seem to change!), Nagra provided a
rather nice universal way of connecting cameras to the VPR-5. This
interface consisted of a special electronics module on one end of
the camera cable and the applicable camera connector on the other.
The electronics module locked into a special mounting rail at the
side of the recorder, and connetcted to the machine with a Cannon
D connector. Each interface module contained the special interface
wiring for the camera such as tally arrangements and how the
camera would start and stop the recorder, and these could be easily
re-configured by changing internal DIP switch settings.

The HL79 interface shown in the above image has a rather nice
'made up' umbilical cable, which is highly flexible, contains a
number of coaxial wires and also has an additional nylon rope for
extra strength. Other camera interfaces might be fitted with
'standard' multiway camera cables.
