TTL: Fully Automatic Wireless Flash Shooting

Using Automatic Wireless Flash with a Single Receiver Unit

Transmitter Unit Setting

• Attach a TT685IIO camera flash on the camera and set it as the Transmitter unit.
• M/A/B/C can be set as TTL respectively.

Receiver Unit Setting

• Set wireless controlled TT685IIO as the wireless Receiver Unit.
• You can choose A/B/C/D/E

Check the communication channel.

• If the Transmitter unit Receiver unit(s) are set to a different channel, set them to the same channel.

Position the camera and flashes

• Position the camera and flashes as the picture shows

Check that the flash is ready

• Check that the Transmitter flash ready indicator is ligtened.

Check the flash operation.

• Press the Transmitter unit’s Test Button < >
• Then, the Receiver unit will fire. If not, adjust the Receiver unit’s angle toward the Transmitter unit and distance from the Transmitter unit.

Using Automatic Wireless Flash with Multiple Receiver Units

When stronger flash output or more convenient lighting operation is needed, increase the number of Receiver units, and set it as a single Receiver unit. To add Receiver units, use the same steps as setting “automatic wireless flash with a single Receiver unit”. Any flash group can be set (A/B/C/D/E). When the number of Receiver units is increased, and the Transmitter unit flash firing is ON, automatic control is implemented to make all groups of flashes fire the same flash output and ensure the total flash output up is to standard exposure.

• If the Receiver unit’s auto power off function is workable, press the Transmitter unit’s test button to power it on. Please note that test firing is unavailable during the camera’s regular metering time.
• The effective time of Receiver auto power off is changeable.

Using Fully Automatic Wireless Flash
The FEC and other setting that set on the Transmitter unit will also be appeared on the Receiver unit automatically. The Receiver unit does not need any operation. Use the following settings to make wireless flashes according to the same methods with normal flash shooting.

• Flash Exposure Compensation

About the Transmitter Unit
Use two or more Transmitter units. By preparing several cameras that with Transmitter units flash attached, cameras can be changed in shooting while keeping the same lighting source. (Receiver unit).

M: Wireless Flash Shooting with Manual Flash
This describes wireless (multiple shooting) using manual flash. You can shoot with a different flash output setting for each Receiver unit (firing) group. Set all parameters on the Transmitter unit.

Setting Flash Mode
You can directly operate the Receiver unit to manually set the manual flash or stroboscopic flash. ****

The Reason & Solution of Not Triggering in Godox 2.4G Wireless

1. Disturbed by the 2.4G signal in outer environment (e.g. wireless base   station, 2.4G wifi router, Bluetooth, etc.)
   • To adjust the channel CH setting on the flash trigger (add 10+ channels) and use the channel which is not disturbed. Or turn off the other 2.4G equipment in working.
2. Please make sure that whether the flash has finished its recycle or caught up with the continuous shooting speed or not (the flash ready indicator is lighten) and the flash is not under the state of over-heat protection or other abnormal situation.
   • Please downgrade the flash power output. If the flash is in TTL mode, please try to change it to M mode (a preflash is needed in TTL mode).
3. Whether the distance between the flash trigger and the flash is too close or not ( <0.5m)
   • Please turn on the “close distance wireless mode” on the flash trigger
   • X2 & X1 series: press the test button and hold on, then turning it on until the flash ready indicator blinks for 2 times.
   • XPro series: Set the C.Fn-DIST to 0-30m.
4. Whether the flash trigger and the receiver end equipment are in the low battery states or not.
   • Please replace the battery (the flash trigger is recommended to use 1.5V disposable alkaline battery).

Other Applications

Sync Triggering
The Sync Cord Jack is a Φ2.5mm plug. Insert a trigger plug here and the flash will be fired synchronously with the camera shutter.

Bounce Flash
By pointing the flash head toward a wall or ceiling, the flash will bounce off the surface before illuminating the subject. This can soften shadows behind the subject for more natural-looking shot.

This is called bounce flash
To set the bounce direction, hold the flash head and turn it to a satisfying angle.

• If the wall or ceiling is too far away, the bounced flash might be too weak and result in underexposure.
• The wall or ceiling should be a plain, white color for high reflectance. If the bounce surface is not white, a color cast may appear in the picture.

Creating a Catchlight
With the catchlight panel, you can create a catchlight in the subject’s eyes to add life to the facial expression.

1. Point the flash head upward by 90°
2. Pull out the wide panel. The catchlight panel will come out at the same time.
3. Push the wide panel back in.
   • Push in only the wide panel.
   • Follow the same procedures as for bounce flash.

Notes

• Point the flash head straight ahead and then upward by 90° The catchlight will not appear if the swing the flash head left or right.
• For maximum catchlight effect, stay 1.5m/4.9ft away from the subject.

ZOOM: Setting the Flash Coverage
The flash coverage can be set automatically or manually. It can be set to match the lens focal lengtha from 20mm to 200mm or 10mm to 100mm.

In Manual Zoom mode, press the button. 

• Turn the Select Dial to change the flash coverage.
• If < > is displayed, the flash coverage will be set automatically

If you set the flash coverage manually, make sure its covers the lens focal length so that the picture will not have a dark periphery.

Low Battery Warning
If the battery power is low < > will appear and blink on the LCD panel. Please replace the battery immediately

Protection Function

Over-Temperature Protection

• To avoid overheating and deteriorating the flash head, do not fire more than 40 continuous flashes in fast succession 1/1 full power. After 40 continuous flashes, allow a rest time of at least 10 minutes.
• If you fire more than 40 continuous flashes and the fire more flashes in short intervals, the inner over-temperature protection function may be activated. If this occurs, allow a rest time of about 10 minutes, and the flash unit will then return to normal.
• When the over-temperature protection is started is shown on the LCD display.

Number of flashes that will activate over-temperature protection:
Power Output Level / Number of Flashes / ZOOM (mm)

Number of flashes what will activate over-temperature protection in high- speed sync triggering mode:
Power Output Level / Number of Flashes / ZOOM (mm)
