Figure F117. A. Photograph of the top of the PAT-195 around the recorder frame of the SAM-195. The recorder frame has a mechanism that will allow a remotely operated vehicle (ROV) to eject the SAM-195. Two underwater mateable connectors (UMCs) for the lithium battery unit (LBU) and MEG-195 are also seen. MEG = multiple-access expandable gateway, SAM = storage acquisition module. B. Photograph of the recorder frame, viewed from the bottom. The SAM frame has a guide wedge, or key, inside the SAM hole because the connector on the bottom of the SAM-195 canister must be correctly positioned to mate. The SAM-195 can be set and ejected by an ROV-operated lever mechanism in the recorder frame.
