I have a nikon d5500 and am trying to execute off camera

This answer was rated:

I have a nikon d5500 and am trying to execute off camera flash. With transmitter in hot shoe I can manually trigger my neewer 750ii speed light from across the room. However, I can't get the camera to signal the transmitter to fire the speed light. What should my camera settings be? Thank U.
JA: What's the exact make and model of the camera? And can you guesstimate how old it is?
Customer: Nikon d5500 1yr 6 months old.
JA: How long has this been going on? What troubleshooting have you tried?
Customer: 1 week. I know the camera can do it cause i've done it before. Fresh batters, reseated in hotshoe, test firings with transmitter off and in shoe (successful). Reboots, complete removal of power from all units.
JA: Anything else you want the Electronics Expert to know before I connect you?
Customer: I know it works i've used the feature before. I'm sure it's about a camera setting. Again tx to flash works. tx on camera to trigger flash does not.

On the flash I've tried TTL and Manual modes.

Hi, I'm Pete. Welcome to JustAnswer! I'm reviewing your question now, and will post back with your reply ASAP.

1. Choose one of the manual exposure modes (PASM). Press the Menu button. Find the Custom Setting Menu and within this, choose the Bracketing/Flash option.

2. Scroll down until you see the Flash cntrl for built-in flash option. Select it.

3. Next, choose Commander mode which will present you with many different options on the screen. Because the pop-up flash is being used to trigger the speedlight that is off-camera, it needs to be raised in order for the wireless system to work. You do get the option of including the output of the pop-up flash in your exposure which you can set on this screen. In this example we want to have the flash fire, but not be included in the final exposure, so in the Built-in flash option on the menu, change the option to the two dashes, or off.

Then you will have the option of using groups for different flashes. Leave everything as it is: that is, Group A and B on TTL.

TTL stands for 'Through The Lens', which is Nikon's way to measure the flash exposure during the actual exposure of the image. Keep it on this setting so the camera does all the work for you, until you are comfortable with controlling more options on the flash itself.

Make note of the channel that the camera is firing on. By default, this is set to channel 1. Make sure to press OK to save selections rather than going back through the menus.

4. Pop up the flash on your dSLR -- don't forget this step otherwise your wireless system won't work!

5. Turn on the external flash unit and look for a remote option at the back. Select the remote option and make sure that the flash is set to TTL mode to match the camera.

6. Position the flash wherever you like, as long as the sensor at the front of the flash unit is within line of sight of the camera.

Your satisfaction is my priority; I hope I have earned 5 stars today!

Nikon D5500's don't have a commander mode and cannot do high speed sync.

Ok, as it doesn't have commander mode you will need to use a commander unit to control the off camera flash.

Is this what u mean by commander unit? I call it a transmitter(tx) and receiver (rx). I was trying to attach a pic but it didn't work. I have a neewer transmitter (which goes in the camera shoe) and a receiver (which goes on the flash). Is that what u mean when u say "commander unit"? They are all set to the same channel and I've tested all 4 channels.

I didn't get an answer to my question.

The commander unit is the unit that you attach to the camera.

Hi Pete. I'm sorry but i'm a little confused. In my initial question I related that i'm using a trigger (transmitter) to signal my off camera flash. Is this the "commander" you're referring to? I'm calling it a trigger and/or transmitter. You're saying commander. Are we talking about the same thing? Neewer 16 Channel Wireless Remote FM Flash Speedlite Radio Trigger If we're not talking about the same thing, can you give a searchable example.

Hi Pete, I gave U a good rating because I didn't want to get U in any type of trouble but I still don't have an answer to my question. What U suggested I noted as done in my original question. Please consider reviewing my issue. Thanks Pete.
