Pinout for the gripper cable for Scorbot Controller-A

[ElectroNick]

Hi all, looking for the pinout of that little DB9-DB9 cable that gets installed between a motor control card in the Controller-A and its 50-pin breakout board. For some mysterious reasons all other robot's axis are internally connected to that 50-pin connector which you plug your Scorbot V+ robot into but the gripper requires an additional external cable.
I have the Controller and the robot, all axis work except the gripper and I don't want to just guess the pinout, so your help in the matter will be greatly appreciated!
Thanks!
