Need Remote Code or type for Marsh P2000

I have a Marsh MSD P2000 linestage. I thas an Alps RN 297815 motorized pot. I'm trying to find a remote or remote codes for the linestage volume pot. I'm also looking for Schematics. If anyone can help it would be great. Thanks
I looked at the pot and it is an Alps RN 297815. I"m trying to find a remote code for a universal remote or a Marsh Remote. Either will suffice. Help!
Check out the logitech harmony remote. I bought one at Best Buy for $50. It has controlled every piece I've tried it with. You can check their web site to find out if it will control your Marsh.
