This 2-Pin Sync Cord Connector from Sea & Sea is designed for use with Nikon and Canon MDX and RDX series underwater DSLR camera housings equipped with accessory ports. It provides a hard-wired sync cord connection for manual flash exposure and will connect to #17100 or #03470 N-Type sync cords, available separately. It features a 2-pin input and a 5-pin output. The connector also includes an O-ring for a watertight seal.
Remove the accessory port connector cap from the housing. Attach the sync cord connector to your sync cord and insert it into the port. Next, inside the housing, insert the O-ring into the groove on the sync cord connector. Now attach the flat plug end of the sync connector cable to the connector and mount the other end onto the camera's accessory shoe. Outside the housing, attach your sync cord to your external strobe.
