CONNECTIONS
The rear module to be used with the V1642 is the same as that used with the V1645 Noise Reducer and
V1647 Aspect Ratio Converter. Some early units were delivered with rear modules that did not have a
D-type connector for GPI, in which case the Fade to Black input used two lower BNC connectors. Both
types of rear connector are shown below.

On the GPI connector some pins may carry other signals when used with compatible units. Therefore
only use pins 6 and 9 for the Fade to Black Function.
