Does anyone remember seeing a "Fanuc" brand BTR model A16B-1200-027?

I have a 6M-B on Mori Seiki MV45/40 with one in it. I opened the cabinet to look for a location to mount a new to me BTR and found this one already there.

I have some documentation on it but can't get it to work. I think my problem is with the rs232 protocol.

Does anyone remember using one? Has old documents for one? User instructions? Heard of one?


Thanks
