Help Needed Pinnacle Movie Box

[Robert Rothgery]

Our studio recently purchased a Pinnacle Movie Box.  The instructions 
have gone missing and I cannot get any information from Pinnacle.
Does anyone know the dip switch settings for a G-4?  Do the large arrow 
symbols that point in and out respectively indicate inputs and outputs?
Your assistance would be greatly appreciated.
