The SU-4 Wireless Remote TTL Flash Controller enables wireless remote flash with automatic TTL or manual exposure control.
Can be attached to some current and prior Nikon Speedlight models and cameras.
The SU-4 detects the firing of the master flash (including a built-in Speedlight) and sends a firing start signal to the slave unit.
It eliminates the need for a connecting cord. The SU-4 operates effectively up to 25-ft. from the location of the main flash.
The SU-4 Wireless Remote TTL Flash Controller allows for remote flash operation with some current and previous Nikon Speedlights and camera models.
The SU-4 also terminates the firing of the slave flash when it detects the firing stop signal.

SU-4 Wireless Remote TTL Flash Controller 5 5 1 1
It is old but does what it has to do, brilliantly! I got it for my sb-700 flashlight, and then discovered that it was not necessary as my D7000 has commander flash available. But the SU-4 eliminates the annoying sound of the flash and has perfect timing with my camera, it can also be used with flashes with no wireless features like the SB-400, cool!! February 9, 2011

Answer: 
If using the SU-4 then yes, but in SU-4 the cameras built flash will also fire the SU-4, bear in mind though that you will have to set the flash munually as you will not have TTL control.

Answer: 
Yes you can use the SU-4 with the SB-600 off camera but you will have to set the flash power etc manually. The SU-4 doesnt attach to the camera.

Answer: 
The SU-4 cannot be mounted onto the D60. You will need to mount the SB-600 on the SU-4 and use the D60 built in flash to trigger the SB-600. When the built in flash fires, the the SB-600 will fire in sync with the built in flash.

Answer: 
I read that it was compatible with automatic TTL or manual exposure control in the instructions. What I would like to know is if the SU-4 is compatible with iTTL specifically.

As asked: "Will it read the pre-pulses and respond like the SU-600, SU-800, SU-900...?" Thanks.

Can I use the SB600 mounted on the SU-4 and have the built-in flash from the D3000 trigger the SB600? Will the SU-4 properly fire and quench the SB500 automatically? How do I set the D3000 not to send out preflashes and still have TTL flash metering?

Answer: 
Yes, you can use the SB-600 mounted in the SU-4 (will convert the speedlight into an optical slave) and trigger it with the flash from the D3000. Please note that pre-flash may occur if there's low light condition for metering.

Answer: 
The SU-4 will detect the firing of any flash in order to trigger the slave unit, but we cannot guarantee functionality with a third party product.
