This very useful box of tricks controlled operation of the PMD/W-6, acting as an extended intervalometer and a remote AC power source for the RTS/RTSII and PMD/W-6. It was ideal for use in studios, laboratories and surveillance systems.

Intervals could be set anywhere between 1 sec and 24 hours, though the maximum number of frames that could be shot was limited to 99. This was a minor nuisance when using the 250 Film Back.

A bright, red LED display showed the settings as well as the frame count-down.

This is a very rare unit to find.
