SU-4 mode makes the SB-700 a simple optical slave. As soon as it detects a flash it will fire. With the D7000 built in Speedlight set in TTL mode or Commander mode, the pre-flash sequence will trigger the SB-700 before the shutter opens. To have the SB-700 sync in SU-4 mode you must set the built-in Speedlight to Manual flash mode. It will then sync at all shutter speeds up to 1/250th sec.
If you want to take advantage of i-TTL flash control, Go into the camera menu Custom Setting (pencil icon) e3 Flash Cntrl for Built-in Flash Set it to Commander Mode Verify that Goup A is set to TTL then select a channel then press OK. Set the SB-700 to Remote mode. Group A and the same channel you selected in the camera menu. Your should be ready to go.
