FSBus NG I/O board Analogue Input

Hi All,Can any users tell me if they have found a way round the problem that seems to exist on the Analogue input of this board.It appears to work normally(0 to 221) in Fsadmin but in FSRouter the value for any input goes from 0 to 128 then goes negative.Even if you assign something to this and use the postive part it seems very slow.I didread one post of someone with similar problems but nothing else.I dont want to have to hang something else in or use the gameport just for analogue input.Classic used to work well.Just wished i hadnt dismantled my Classic setup now.Any comments help would be appreciated.ThanksLes
