Nikon SC-19 TTL Multi-Flash Sync Cord With Original Box And Instructions - New In Box! SC-18/19 TTL Multiflash Sync Cord and AS-10 Multiflash AdapterLike the SC-17 TTL remote cord, SC-18 is also a TTL remote cord. Unlike the AS-E900 and SC-17, both ends of SC-18 have Nikon's TTL connectors rather than hot shoes. SC-18 and SC-19 are 5' and 10' in length. See the left image below. One end of SC-18 screws into the TTL multiflash terminal on the camera, and the other end into the TTL multiflash terminal on the flash unit. However, not all Nikon flashes have TTL multiflash terminals. For example, Speedlight SB-28 has one, but SB-22s does not. If your flash does not have a TTL multiflash terminal, you will need a AS-10 TTL multiflash adapter. Screw the other end of SC-18 into the TTL flash terminal (see the right image below) and install a Nikon TTL compatible flash on the hot shot of AS-10. Then, you will have a setup (i.e., SC-18 + AS-10) equivalent to that of SC-17 + AS-E900. Moreover, SC-18 + AS-10 is lighter because this setup has only one hot shoe, and is longer because it is not coiled.Note that multiple SC-18 and SC-19 can be plugged into a AS-10 or SC-17 for multiple flash operation.
