GR 3750 Interface I/F PCB card installation

[nervously]

Hello,
I just bought a RIP and a I/C pcb card for my GR3750. I just don't know how to install it. Is there anybody who can help me with this? Or can I find a manual with images somewhere?

Thanks a lot in advance!

I already found out how to do it. For anyone who's interested, here is the solution. One thing seems to be important: The dip switch has to be on OFF position for the GR3750 and on ON position for the GR3790.
