I am working on a dual gripper installation with a new Hand-E gripper and a 3 to 4 year old 2F-85 gripper. I can't get both grippers to work at the same time. They both work without issues if the other one is not connected but when I connect both, only the 2F-85 is recognized and can be initialized. I'm thinking the 2f-85 may have older firmware that does not support this dual gripper setup. I was wondering if there's any special sequence that needs to be followed. I read the manual and I think I followed the steps as described.
