Cubase Artist 6 with Tascam DM4800...questions

My name is Dom. I am new to the forum. I am currentyl using Cubase Artist 6 on Windows 7 home premium 64bit and controlling it with a Tascam DM4800 via firewire and USB. Everything is working fairly well I just have a few questions. First, is there a way to calibrate the level lights on the DM4800 to match with Cubase? The lights peak out long before Cubase peeks.

Second, in remote mode, the board sliders respond with the Cubase on screen mixer but does not with input/buss mixer… The input level does change but does adjust the on screen mixer sliders or vise-versa. Is there away to fix this?

Thank you…
