NSM Prestige E160 Setup

Hi I have recently been given a Prestige NSM E160. The muppet who gave it to me replaced the control/credit unit and fiddled with the jumper settings on it. Can someone send me a pic of the configuration so i can set it up properly. The unit has part number 103760 printed on it and has a sliding cover so you can access the jumpers. any help would be appreciated ....I think you can also set up free vend with the jumpers so any help with that would be good...

Cheers Glenn
