Notices 24. Warranty 1. Getting to Know the Cactus V6 II Thank you for purchasing the Cactus Wireless Flash Transceiver V6 II. Compared with its predecessor V6, the Cactus V6 II allows you to command different brands flashes off camera below or above x-sync speed. The freedom to adjust shutter speed equips you the best flexibility in controlling apertures and power levels the possibility are endless!

1.1 Special Features 1. Cross-brand wireless manual power control of Canon, Fujifilm, Nikon, Olympus, Panasonic, and Pentax flashes;

2. Two cross-brand high-speed sync modes: Normal HSS and Power Sync;

- Normal HSS supports shutter speeds up to 1/8000s;

- Power Sync boosts flash contribution above x-sync shutter;

3. Rear curtain sync and slow sync supported;

4. Multi-master supports up to 16 photographers firing the same set of flashes at their own power setting;

5. AF-assist LED illuminates focusing blind spot when needed;

6. Flash specific profiles with calibrated power levels for many current and previous flash models;

7. User calibration of flash profiles to ensure accurate power output;

8. Lo Power mode fires the flash for extremely short lengths of time;

9. Absolute Power mode benchmarks the power output of different flash models to the same light intensity;

10. TTL pass-through with Canon, Nikon, Fujifilm, Olympus, Panasonic and Pentax via one single unit;

11. Group control allows you to control up to four groups;

12. Relay mode triggers the camera shutter and flash in sync;

13. Delay mode is configurable from 1 millisecond to 999 seconds;

14. Mini-USB port for optional power supply and firmware update;

1.2 HSS and Power Sync Capabilities Most cameras supports normal flash sync up to its x-synchronization shutter speed

(commonly between 1/160 seconds and 1/250 seconds). Beyond this shutter speed, the cameras and the system flashes will behave differently. The high-speed sync, which is also known as the HSS or FP sync, has to be enabled on the system flash in order to synchronize the flash light with the camera beyond the x-sync shutter. Cactus V6 II supports cross-brand high-speed sync in two ways:

1. Normal HSS: It supports the HSS or FP sync capabilities of the system flashes. While it allows user to adjust power levels, the flash exposure is much lower than the normal flash sync. 2. Power Sync: It syncs with the full power flash pulse without compromises on the flash exposure. While it does not allow power level adjustment, the flash exposure is much higher than the normal HSS mode. 1.3 Auto and Model-Specific Flash Profiles Each flash model has its individual power level characteristics. In V6 II, we have profiled them in two ways:

1. System-specific Auto Flash Profiles: The V6 II can auto detect the camera system of the connected flash and activate the Auto profile that will work with all flash models of the same camera system;

2. Model-specific Profiles: For more accurate power output, users can choose from the V6 II menu the flash profile that would work perfectly with the specific flash model. We have profiled more than 40 popular flash models across a wide range of brands so that the V6 II can precisely control their output levels. With this unique feature, photographers can remotely control the flash power of various flash models, even of different brands!

For flash models that have not been included in the profile list, the V6 II can still work with it by the auto flash profiles. Users could further calibrate the flash profiles in the Cactus Firmware Updater to produce more accurate power outputs. Whether built-in or calibrated from the firmware updater software, the flash profile stored in the V6 II can virtually command the flash to produce ANY power level within the maximum output, and even exceeds what the flash menu allows you to do:

1. Finer increment scales: The V6 can adjust the power level of flash to 1/10 EV step, a much finer increment level than the flash menu itself allows (see Section 12.3 for setting up the EV step). 2. Extremely short firing time: In Lo Power mode, the V6 can f ire flashes for very short lengths of time at extremely low power levels (roughly equal to 1/256), which is beyond the standard flash power range (see Section 12.4 for enabling the Lo Power output). 3. Unified power level scale for different flash models: The V6 benchmarks the light intensity output of different flash models in your set up and commands them to fire at the same power scale (see Section 12.2 for adjusting absolute power). Ready to go? Lets get on board and see what the V6 II can do!

2. Cautions and Warnings Before using your V6, read the following safety precautions to ensure correct and safe use:

1. Turn OFF all your equipment (e.g., Cactus units, flash units, cameras, etc.) before changing batteries or making connections. Observe the correct polarity when changing batteries. There is a danger of explosion if the batteries are installed incorrectly. 2. Switch off the transceiver and remove batteries during storage. 3. Do not permanently store the product in a high temperature environment (i.e., under strong direct sunlight, near cooking stoves/oven). 4. The Cactus V6 II should never be submerged in liquid or exposed to heavy rain unless it is properly protected. 5. Do not operate the device in the presence of flammable gases or fumes. 6.

Compatibility The Cactus V6 II is both a wireless flash trigger and wireless remote control. While it triggers both portable flashes and studio strobe lights, it also supports remote control features with selected flash models. 7.1 Flash & Studio Strobes 7.1.1 Cactus RF60x / RF60 With the built-in Cactus V6 module, the Cactus RF60 series can be remotely commanded and triggered by V6 II TX (see Section 16.1.1). 7.1.2 Flash Models with Digital TTL Mode:

z Canon e-TTL z Fujifilm TTL z Nikon i-TTL z Olympus / Panasonic TTL z Pentax TTL 7.1.3 Other Flash Models and Studio Strobes The Cactus V6 II triggers all other flash models via the hot shoe, and studio strobes with the PC sync male port, 3.5mm or 6.35mm port via optional cables (see Section 19). This includes high trigger voltage portable flash models, and all strobe models with a trigger voltage of 300V or under. The Cactus V6 II does not provide remote power control of these flashes and strobes. For studio flashes to work with high-speed sync, they have to maintain a flash duration of 1/100 second or longer. Caution:

Flashes or strobes with reversed polarity connectors DO NOT WORK with the Cactus V6 series. 7.2 Cameras The Cactus V6 II works with practically all cameras that come with either (1) a standard ISO hot shoe, or (2) a female sync port connection. For the high-speed sync and the AF assist capabilities, the V6 II would support cameras from Canon, Nikon, Olympus, Panasonic and Pentax that (1) comes with their specific system hot shoes, and (2) equipped with the same features with their system flashes. The V6 II supports HSS adaptation To use the V6 II as a wireless shutter release, specific shutter cables are required. For the list of optional accessories, see Section 19. 7.3 Flash Triggers 7.3.1 Cactus V6 The Cactus V6 II is compatible with the Wireless Flash Transceiver V6, V5 and Laser Trigger LV5. See Section 16.2 for details. 7.3.2 Other Flash Triggers The Cactus V6 II is NOT compatible with any other flash trigger model, including the Cactus V2, Cactus V2s, and Cactus V4. 8. TTL Pass-through The V6 II transceiver comes with a multi-system shoe that supports TTL pass-

through. While the V6 II does not command slave flashes to fire TTL exposures wirelessly, it is designed to pass TTL signal from camera to flash via the transmitter (TX) and vice versa. The multi-system shoe supports TTL pass-through of Canon, Fujifilm, Nikon, Olympus, Panasonic, and Pentax systems. Make sure that camera and flash unit belong to the same TTL system. With TTL pass-through, the TTL flashes behave as they would when directly connected to the camera hot shoe. The V6 II will work as a wireless flash commander while supporting all the automatic features (e.g., automatic flash output via TTL metering, AF assist light, second curtain sync, high speed sync/FP shutter) provided by the TTL flash system. To enable TTL pass-through in the V6 TX II, press and hold for 2 seconds. The LCD will show the TTL pass-through indicator at the left bottom corner where the channel indicator used to be.

(image) In TTL pass-through mode, the V6 II TX cannot control the power level of the flash attached. To disable the TTL pass-through mode, press and hold for 2 seconds. The TTL pass-through indicator will be replaced by the channel indicator on the LCD. 9. Getting Started 9.1 Installing the Batteries Open the battery door by pushing it backward. Flip open the latch and insert two AA batteries using the correct polarities. Then close the battery door by pushing it to the front. 9.2 Attaching to and Detaching from the Camera To mount the V6 II on a cameras hot shoe mount:

1. Turn the lock lever of the V6 II to the left to unlock the multi-system shoe (male). 2. Slide the V6 II into the cameras hot shoe. 3. Turn the lock lever of the V6 II to the right to lock the multi-system shoe (male). 4. When detaching the V6 II from the cameras hot shoe, turn the lock lever to the left to unlock the multi-system shoe (male). Otherwise, the multi-system shoe

(male) may be damaged. Note: Attach your flash to the V6 II as you would to the cameras hot shoe. If your flash is not locked securely on the Multi-System Shoe (female), try half-locking the flash and retracting it slightly from the Multi-System Shoe until the locking pin hits the pinhole. Then lock your flash fully to the V6 II. 9.3 Buttons and Dial The V6 II control panel is equipped with a Menu button , an OK button , and a selection dial for quick access to different functions and the configuration menu. The selection dial has a built-in push-in button that serves as a quick OK button. You may configure how the dial works to suit your working habit. (see Sections 17.1 -

(Canon Camera Logo)

(Fujifilm Camera Logo)

(Nikon Camera Logo)

(Olympus Camera Logo)

(Pentax Camera Logo) The V6 II TX is capable of auto detecting the camera system of the attached camera. It facilitates photographers to switch camera system promptly. To initiate the auto detection of camera system:

1. Attach your camera to the V6 II (see Section 9.2) and turn on your camera. 2. If you would like to command a master flash, attach your flash to the V6 II and turn on your flash. 3. Half press the shutter release of your camera while switching on the V6 II to the TX mode;

4. The V6 II will detect the camera system and the flash system of the attached camera and flash during the start up. The LCD screen will show the auto-detected camera and flash system briefly before loading the main screen. 5. To check the detected camera system from the main screen, press and hold the menu button , and turn the selection dial to either direction at the same time. The detected camera system will be shown next to the channel. 6. The V6 II will memorize the detected camera system beyond the power cycle, until the next detection takes place. 10.2 Choose from Menu Alternatively, photographers who mainly work on one camera system may choose it from the menu:

1. Switch on the V6 II in TX mode. 2. Press , and then turn the selection dial to <CAMERA SYSTEM>. Press . 3. Turn the selection dial until the LCD shows your camera system (e.g., <PENTAX>). Press . 4. The V6 II will memorize the chosen camera system beyond the power cycle, until you select another camera system from the menu next time. Note: By choosing the camera system on the menu, the V6 II will disable the auto-

detection of the camera system when it is powered on. If you would like the V6 II to detect the camera system for you, choose <AUTO>. The option will display the camera system detected last time in the brackets (e.g., <AUTO(CANON)>). 10.3 Learn HSS Even when you have assigned the correct camera system, there would be a chance that the camera does not sync with the slave flashes above x-sync speed. This would particularly happen when you fire and command the slave flashes in a different system from your camera. We recommend photographers to initiate the HSS Learn to learn the HSS sync time of each of their camera once:

1. Mount the camera on the V6 II and switch on the V6 II in TX mode. 2. Make sure you have assigned the correct camera system to V6 II by auto detection (see Section 10.1) or menu configuration (see Section 10.2). 3. Press , and then turn the selection dial to <LEARN HSS >. Press . 4. Choose <START> and press . The LCD screen will show <PRESS SHUTTER WITHIN 30 SEC). 5. Full press the camera to take a shot. The LCD screen will then show (LEARN COMPLETED> briefly. 6. The learned sync time will be implemented in that camera system until you initiate another learning again. Notes:

1. The sync time of each camera system will be updated by the last learned result. 2. Changing cameras across system do not need re-learn again. 3. Changing cameras within the same system would need to LEARN HSS every time. 11. Flash Profile: Auto-detect and Customization The V6 II transceiver commands flashes to fire at a particular output via flash profiles. There are three ways to obtain the correct flash profiles:

1. Let the V6 II detect and apply the <AUTO> flash profile (see Section 11.1). 2. Choose from the pre-installed flash profiles in the V6 (see Section 11.2). 3. Customize the auto profile in the Cactus Firmware Updater on a PC or Mac (see Section 11.3).

Canon Fujifilm Nikon Olympus / Panasonic (M43) Pentax 11.1 Detecting an Auto Flash Profile The auto flash profile is camera system specific. It works with all digital flash within the same camera system to produce a moderately accurate (error within 0.3EV) flash output. The V6 II is capable of auto detecting the flash system of the attached flash. 1. Attach your flash to the V6 II and turn on the flash. 2. Switch on the V6 II to the RX mode (for slave flashes) or TX mode (for master flash). 3. The V6 II will detect the flash system of the attached flash during the start up. The LCD screen will show the auto-detected flash system briefly before loading the main screen. 4. The V6 II will memorize the detected flash system after power cycles until the next detection. If you wish to obtain more accurate output that is fine-tuned for your specific flash units, choose the model-specific flash profiles (see Section 11.2) or customize the existing flash profiles (see Section 11.3). 11.2 Choosing a Flash Profile Choose the appropriate flash profile from the pre-installed profile list for each V6 II RX you will use with your flash. 1. Switch on the V6 II in RX mode. 2. Press , and then turn the selection dial to <FLASH PROFILE>. Press . 3. Turn the selection dial until the LCD shows your flash system (e.g., <CANON>). Press . 4. Turn the selection dial until the LCD shows your flash model (e.g., <580EX*>). Press . 5. Connect the flash unit to the V6 II. Switch your flash to TTL mode and your flash will be ready for remote control. The chosen flash profile will be applied until you choose another flash profile. In case you wish to fire and control an on-camera master flash via the V6 II TX, follow steps 2-4 above in TX mode to choose the appropriate flash profile for the master flash. 11.3 Customizing a Flash Profile If your flash model is not included in the pre-installed profile list but support digital TTL, configure the V6 II to the Auto Flash Profile (see Section 11.1). In case you wish to fine tune the power level output commanded by the Auto Flash Profile, you may customize it with the Cactus Profile Editor available to PC and Mac. 1. Follow the firmware update procedures to connect V6 II with your computer (see Section 18.2). 2. Choose the flash system. Input the guide number of your flash at the zoom angle at 105mm (which is the benchmark of the pre-installed profiles in the V6 II). 3. Based on your experience in controlling the flash with the auto flash profile, input the power adjustment that you would like to achieve in each of the reference power level. 4. Enter the profile name in 1-6 letters or numbers. 5. Press STORE PROFILE button. The custom profile will be loaded to the connected V6 II. To choose the saved flash profile from the profile list, see Section 11.2. All custom profiles will be stored under the flash system <CUSTOM> in the <FLASH PROFILE>

menu. Each V6 II can save up to 10 custom flash profiles from the Cactus Profile Editor. Note: The Profile Editor supports profile sharing via codes. When customizing a flash profile, the editor will generate a code representing the changed parameters. You can share this code to friends, or simply enter the code received from others in the SHARE CODE column to generate a new customized profile in a second. 12. Flash Triggering To command the flash units in different groups to fire:

1. Set the V6 II transceivers to the correct mode (transmitter to TX, receiver to RX). This will automatically power on the transceivers (see Section 9.4). 2. Set both TX and RX to the same channel (see Section 9.5). 3. Assign RX unit(s) to A, B, C, or D group and activate the group(s) on the TX (see Section 9.6). 4. Connect the V6 II RX to portable flashes or studio strobes. 5. On the TX, press completely. The status LED of both TX and RX should blink in green simultaneously. The portable flashes or studio strobes will f ire at the same time. 6. Test fire a particular group by pressing the group button and completely and simultaneously. 7. Attach the TX to the cameras hot shoe. If your camera does not have a hot shoe, connect the TX to the camera using an optional PC sync cable (CA-200). 8. Press the cameras shutter release button. The flashes on the RXs will fire wirelessly and in sync. Tips: The V6 II transceiver can trigger portable flashes with or without remote power control. If you wish to wirelessly trigger the slave flashes without controlling their power levels, choose the <OTHER> flash system in the <FLASH PROFILE> menu. 13. Remote Manual Power Control Apart from flash triggering, the V6 II can also command the manual power of your flash. On each RX, choose the appropriate flash profile for each flash to be connected. The V6 II TX will then be able to command the flash to f ire from 1/128 to 1/1 full power. V6 II offers two power definitions for users to command the flashes power in the most convenient way. To remotely control the power of your flash units:

1. Connect the flash units to the V6 II. 2. Switch on the flash units in TTL mode. Then switch on the V6 II in RX mode. 3. Choose the correct flash profile for each V6 II. 4. If you may command the flash to fire above the x-sync speed, turn on the HSS or FP flash on your flash units (see Section 14.1). 13.1 Relative Power Similar to a common flash display, the V6 II TX indicates the power level of the remote flashes in proportion to full power in relative power mode, i.e., 1/1 for full power, 1/2 for half power, etc. Upon switching on the V6 II in TX mode, the LCD will show the relative power levels of all activated groups.

(image) Note that the small single digit indicates the increment between major power levels. 12.1.1 Single Group Power Adjustment There are two ways to adjust the power level of a particular slave group. 1. Press and hold the group button until the power level of the chosen group is highlighted on the LCD. Turn the selection dial to the desired power level. Press shortly the group button to leave the group selection. 2. Short cut: Press and hold the group button and turn the selection dial simultaneously. Once the adjustment is finished, release the group button. You may also adjust the power level of the master flash that you have mounted on the V6 II TX multi-system shoe (female). 1. Make sure that the TTL pass-through mode has not been activated (see Section 8). 2. Press and turn the selection dial simultaneously to change the power level of the master flash. 12.1.2 Multi-Group Power Adjustment To adjust the power level of ALL active groups, simply turn the selection dial left or right to the desired power level. Note: The power level of the master flash is not affected by the multi-group adjustment. 12.1.3 Quick Power Adjustment Mode By turning the dial left or right one click, the power level of the chosen groups will increase or decrease by one step. The EV step in the V6 II factory setting is 1/3 EV. The EV step can be configured to 1/2, 1/3, or 1/10 in the <EV STEP> menu (see Section 12.3). If you wish to quickly change the power level using a larger interval, use the quick power adjustment mode. 1. In the main screen of the V6 II in TX mode, press once to enter the quick power adjustment mode. In this mode, each click of the dial will increase or decrease the power level for 1EV to and from the original value respectively. For example, if the power level of a group was 1/16 +3, one click of the selection dial will increase the power level to 1/8 +3 or decrease it to 1/32 +3. 2. 3. Once you have finished the quick change, press once again to leave the quick power adjustment mode. Each click of the dial thereafter will increase or decrease the power level in accordance with the setting you have made in the

<EV STEP> menu. 13.2 Absolute Power If you want to coordinate the light output of multiple flashes with different maximum power outputs, the regular power ratios such as 1/4 or 1/8 may not be as helpful. The output of one powerful flash model at 1/8 can be higher than that of another, weaker flash model at 1/4. For this reason, the V6 II offers an absolute power mode in which EV numbers can be used to specify an absolute light intensity, independent of the maximum power output of a flash model. The power levels in guide number have been rescaled to the absolute power scheme in EV as below:

ABSOLUTE LIGHT INTENSITY IN EV GUIDE NUMBERS (IN METERS)

+0.0

+0.3

+0.5

The following example shows how the model-specific relative power scales are translated into the absolute power scale. ABSOLUTE LIGHT INTENSITY SCALE IN EV 18 17 16 15 14 13 12 11 10 9 8 7 6 RELATIVE LIGHT INTENSITY SCALE OF 4 FLASHES WITH DIFFERENT FULL POWER GUIDE NUMBERS FLASH A GN29 1/2 1/4 1/8 1/16 1/32 1/64 1/128 FLASH D GN41 1/2 1/4 1/8 1/16 1/32 1/64 1/128 FLASH B GN58 1/2 1/4 1/8 1/16 1/32 1/64 1/128 FLASH C GN21 1/2 1/4 1/8 1/16 1/32 1/64 1/128 When you set all flashes to 11 EV (see italicized section in the above table) in absolute power mode, all flashes will emit the same intensity of light notwithstanding the differences in their own relative power scale. For instance, at 11 EV, Flash A is firing the amount of light equal to its 1/16 power, while Flash C is firing equal to its 1/8 power.. To change the V6 II system to the absolute power mode:

1. Switch on the remote V6 II in RX mode. Choose the correct flash profiles for each of the V6 II RXs. 2. Switch on the V6 II that you would like to be the commander in TX mode. Make sure that it is on the same channel as the RX units. Press . Turn the selection dial to <POWER MODE> and press . Turn the selection dial to <ABSOLUTE

(SETUP)> and press to confirm. 3. The V6 II TX will then collect the flash profiles from the V6 II RX units and set up the absolute power level scheme. Once the set up is finished, the LCD display will return to the main screen again and show the absolute light intensity of the four groups. 4. Adjust the power level as you do in relative power mode (see Section 12.1). Each figure before decimal place represents 1 EV and the smaller figure thereafter 1/10 EV.

(image) 5. Set all the activated groups to the same power level. Test f ire the slaves and 6. determine whether they produce the same flash output. If the initial set up is not accurate enough, you may offset the absolute power scale of each group. Press any group button and simultaneously to get into the offset mode for that group. For example, if the flash output of group A is slightly stronger than the other groups at the same absolute power levels, press and simultaneously. The LCD screen will show <GROUP A OFFSET>. Turn the selection dial left or right to adjust the power scale from -1EV to 1EV. Press to return to the main screen. Note: The absolute power set up will not be saved upon switching off the V6 II TX. The V6 II TX will restart in relative power mode. 13.3 EV Step The control panel of the V6 II TX offers three EV step options: 1/10 EV, 1/3 EV, and 1/2 EV. The configuration applies to both relative and absolute power modes. To adjust the EV step, switch on the V6 II in TX mode and press . Turn the selection dial to <EV STEP>. Press and turn the dial to the desired increment level (1/10, 1/3, or 1/2). Press to confirm. Notes:

1. The selected EV step will be memorized upon switching off and will be applied 2. when switching on again. In the quick power adjustment mode (see Section 12.1.3), the configured EV step will be replaced by the 1EV step changes. 13.4 Lo Power At the Lo Power level, the relative power output of a flash triggered by the V6 II is roughly equal to 1/256. The difference between 1/128 and 1/256 power outputs may be hardly detected by flash meter, but the extremely short firing duration helps freeze faster-than-lightning moments and is ideal for high-speed photography. To enable Lo Power:

1. Switch on the V6 II in TX mode and press . Turn the selection dial to <Lo POWER> and press . Turn the selection dial to <ON> and press . 2. Once the Lo Power is enabled, the Lo Power will be shown as <Lo> at one step below 1/128 power in the relative power mode, or one step below the lowest power of each group in the absolute power mode. 3. To disable the Lo Power output, follow step 1 to enter the Lo Power menu. Turn the selection dial to <OFF> and press . 14.High Speed Synchronization The HSS capabilities of V6 II are designed to support flash photography at shutter speeds beyond a cameras maximum sync speed. To this end, the V6 II will command the remote flashes to fire either flashes with an extended duration or a full power normal flash to produce even frame illumination at shutter speeds as high as 1/8000 second. Tip: HSS flash is commonly used outdoor, especially in sunlight. The faster shutter speed supported by HSS flash allows you to use a wider aperture to achieve shallower depth of field while maintaining correct exposure. Setup for Multi-brand 14.1 High speed synchronization has to be operated in a highly precise manner. Apart from the system-wise profile, we recommend you to input your camera-specific profile to the V6 II before you command the V6 II to high-speed synchronization with flashes from multi-brands. 14.1.1 Learn HSS. Let V6 to learn HSS with your camera (see Section 10.3) 14.1.2 Maximum X-sync Speed:

Canon and Olympus (M43) users have to set up the maximum x-sync speed of their camera once before working in any of the high speed sync mode. Check with your camera specifications to find out the maximum x-sync speed supported before the setup. 1. Press . Turn the selection dial to <SUB-MENU>, press . 2. Turn the selection dial to <MAX. X-SYNC SPD.>, press . 3. Turn the selection dial to choose the correct maximum sync speed, press . The V6 II will memorize the setting after power cycles until further changes. Change the setting There is no need for Nikon and Pentax cameras to configure the maximum x-sync speed. 14.2 Normal HSS When the shutter speed of the camera exceeds its x-sync speed, the normal HSS setting of the V6 II would command the remote flashes to fire continuous and constant flash pulse for the full duration between the first curtain opening and second curtain closing when the shutter speed of the camera exceeds the x-sync speed. In some camera systems, it is also known as focal plane or FP flash. To command the flash units to fire the HSS flash when your camera shutter speed exceeds the x-sync speed:

1. Configure the V6 II TX and the V6 II RX to the correct camera and flash systems

(see Section 10 and 11). 2. Switch the V6 II TX to the normal HSS mode. On the V6 II TX, press . Turn the selection dial to <HIGH SPEED SYNC> and press . Turn the selection dial to

<NORMAL HSS> and press . On the status screen of the LCD screen, the HSS icon (ILLUSTRATION OF HSS ICON) would be shown. 3. Turn on the HSS or FP flash option on the flash units. 4. In case the camera does not completely sync with the slave flashes above x-sync speed, proceed to <LEARN HSS> once for your camera (see Section 10.3). Note: The continuous light output of normal HSS flash does not freeze a moving object as a normal flash would do. Instead, it will cause motion blur, much like a continuous light source would. In order to freeze motion in normal HSS flash, you need to use high shutter speeds. 14.3 Power Sync As an alternative to the normal HSS, the Power Sync of the V6 II syncs with the full power flash of the remote flashes. Power Sync yields a much higher exposure than the normal HSS flash. To command the flash units to Power Sync when the camera shutter speed exceeds the x-sync speed:

1. Configure the V6 II TX and the V6 II RX to the correct camera and flash systems

(see Section 10 and 11). 2. Switch the V6 II TX to the normal HSS mode. On the V6 II TX, press . Turn the selection dial to <HIGH SPEED SYNC> and press . Turn the selection dial to

<POWER SYNC> and press . On the status screen of the LCD screen, the Power Sync icon (ILLUSTRATION OF POWER SYNC ICON) will be shown. 3. Switch the camera shutter beyond its x-sync speed and take a shot. 4. If the frame is not evenly illuminated from top to bottom, go back to the <HIGH SPEED SYNC> menu (repeat step 2). Press and hold , turn the selection dial simultaneously to offset the sync time. When you see a dark band at the top of the image, offset the sync time to positive (to delay the default sync time). When the dark band appears at the bottom, offset the sync time to negative (to shorten the sync time). Note: Since the Power Sync always command the remote flashes to fire in full power, the power level cannot be adjusted. The power levels on the main screen is to be executed when the shutter speed is within the x-sync. 15.Camera Shutter Release Note:

This function requires the use of a separately purchased shutter release cable for connection between the transceiver and camera. This cable is NOT included in the V6 II transceiver package. 15.1 Basic Setup

(image) A minimum of two Cactus V6 II transceivers is required to operate Cactus V6 II as a wireless shutter release. 1. Connect the V6 II RX to your camera using an appropriate shutter release cable. 2. Set both the V6 II TX and RX to the same channel. On the V6 II TX, activate the group assigned to the V6 II RX. 3. Half-press on the TX to test the auto focus. The status LED on both the TX and RX will turn ORANGE to indicate auto focus. Press completely on the TX for shutter release. The status LED on both transceivers will turn GREEN to indicate shutter release. 15.2 Bulb Mode 1. Set the camera to Bulb. 2. Press completely and hold on the V6 II TX. The status LED on the V6 II TX and V6 II RX will turn green at first and go off after approximately 2 seconds. The LCD display will show <BULB MODE ON>. 3. Release on the V6 II TX. The cameras shutter is now in a continuous open state. 4. To close the cameras shutter, press completely and release on the V6 II TX again. The green status LED on both the TX and RX will blink simultaneously. 15.3 Relay Mode: Camera Shutter + Flash

(image) The relay mode in the V6 series is an economic solution for coordinating the wireless shutter release with flash trigger systems. With relay capability, you need only 3 transceivers to wirelessly control both the camera and a flash unit at one time. 1. Make sure that all the V6 II units are set to the same channel. 2. Set the V6 II that you would like to use as the handheld remote as TX, then all others as RX. 3. Mount one of the V6 II RXs onto the cameras hot shoe, and also connect the V6 II RX to the cameras shutter release port with an appropriate shutter release cable (optional). Connect the other V6 II RXs to the flash units. 4. On the on-camera V6 II RX, press . Turn the selection dial to <RELAY>. Press .Turn the selection dial to <ON>. Press to confirm and then press to return to the main screen. The relay mode indicator <REL-C> will appear on the main screen. In the handheld V6 II TX unit, press . Turn the selection dial to <RELAY>. Press and turn the dial to <ON>. Press , then press to return to the main screen. The relay mode indicator REL will replace the channel indicator. 5.

(image) 6. By pressing on the TX, both the camera and flash units will be triggered and sync with each other. In addition, you will also be able to control the power level of the flashes with your V6 II TX. 7. To exit the Relay mode in both TX and RX units, press and turn the selection dial to <RELAY>. Press and turn the selection dial to <OFF>. Press and then press to return to the main screen. 16.Advanced Operations 16.1 Autofocus Assist Light The V6 II is equipped with an autofocus assist LED and is capable of supporting the auto-focus assist signal from configured camera system. The power of the LED light could be adjust to best suit your working environment. To configure the AF assist LED:

1. Switch on the V6 in TX or RX mode, press , and turn the selection dial to

<SUB-MENU>. Press . 2. Turn the selection dial to <AF-ASSIST POWER>, press . You would then be able to turn on and select the power of the AF assist LED. Note: The V6 II TX completely replicates the AF signal commanded by the connected camera. If the camera does not support AF assist signal via the hot shoe, the AF assist LED would not be activated. 16.2 Multi-master The V6 II supports up to 16 TXs working together in a lighting set up. Photographers can share the same set of remote flashes and command them to fire the power output without being influenced by the others. There is no need to configure on the V6 II menu to support multi-master. By the time the any of the photographer in the group presses the shutter, the V6 II TX would trigger the RXs and command the flash to fire the configured power levels from that specific TX. Note: If two TXs are triggering at the same time, the RXs may interfere with each other. It is recommended to the photographers in the set up to shoot one by one. 16.3 Delay Timer

(image) Every V6 II is equipped with a delay timer that is configurable in either the TX or RX mode. The delay timer delays the trigger response for the time period set. If you wish to f ire the flash a bit later than the first curtain sync to create a different light effect

(e.g., to achieve a second curtain sync), set an appropriate delay time from 1 millisecond to 99 seconds. 1. Switch on the V6 in TX or RX mode, press , and turn the selection dial to

<DELAY>. Press . 2. To set a delay time in millisecond, turn the dial to <SET MS> and press . Turn the dial to set each digit and press to confirm and move to another digit. 3. To set a delay time in millisecond, turn the dial to <SET SEC> and press . Turn the dial to set each digit and press to confirm and move to another digit. 4. The status screen of V6 TX and main screen of the V6 II RX will show the status of the delay timer (see Section 6.2). Group Sequence 16.4 There may be some situations in which you would like to f ire the slave groups in a very short sequence:

y Post-production of high dynamic range (HDR) photos: In burst mode, y y photographers can take two pictures of the same scene with contrasted flash power levels very quickly. The resulting pictures can be very handy in the post-

production of HDR photos. Evaluating the individual contribution of the slave groups: Taking a series of pictures in burst mode will allow you to review the contribution of each slave group individually. Speed up the flash cycle: When you need to f ire a series of flashes at high power levels, assign two or more flashes to different groups and adjust them to the same power level. Alternately f iring the flashes will let the capacitors recharge during the longer interval, ensuring enough charge for the next high power output. The V6 II offers two group sequence modes for selection:

A-B-C-D: The first trigger in a series will f ire group A, then group B, and so on. The fifth trigger will f ire group A and start the cycle again. Another series will restart at group A when there is no triggering event in 2 seconds.

(image) AB-CD: The first trigger in a series will f ire group A and B together, then group C and D. The third trigger will f ire group A and B, and start the cycle again. Another series will restart at group AB when there is no triggering event in 2 seconds.

(image) 1. Switch on the V6 II in TX mode. Press , and turn the selection dial to <GROUP SEQUENCE>. Press . 2. Turn the selection dial to A-B-C-D or AB-CD and press . 3. Depending on the group sequence mode you set, one or two cursors will point to the group alphabets on the main screen, indicating which group(s) will be f ired next. 17. Personalizing the V6 II You may configure a number of personalized options in the SUB-MENU of the V6 II to suit your needs. Press and turn the selection dial to <SUB-MENU>, then press . Turn the selection dial again will scroll through all the personalized options. 17.1 Selection Dial Direction In <DIAL DIRECTION>, the selection dial of the V6 can be configured to operate in a

<CLOCKWISE> or <ANTI-CLOCKWISE> direction. To increase the power level in the main screen, for example, you would have to turn the selection dial to the left in the clockwise setting, or turn it to the right in the anti(counter)-clockwise setting. 17.2 Selection Dial Lock To prevent unintended turning of the selection dial and its consequence of affecting the power levels, the dial can be locked in the main screen of the TX mode:

1. To lock the selection dial, press and hold the selection dial or for 2 seconds. The LCD will show [lock] at the left upper corner. 2. To temporarily unlock the selection dial, press the selection dial or once. Alternatively, press and hold any group button to select a group for power level adjustment. The LCD will show [unlock] to indicate the temporary unlock status. The dial will be locked again when no button or dial is pressed or turned in 2 seconds. 3. The temporary unlock mechanism can be enabled or disabled in the

<TEMPORARY UNLOCK> sub-menu. 4. To permanently unlock the selection dial, press and hold the selection dial or for 2 seconds. Note: The short-cut for adjusting the power level of a single group by pressing a group button and turning the dial simultaneously (see Section 12.1.1) will be unaffected. 17.3 Swap Control In the main screen of the V6 II TX, pressing or the push-in selection dial once will change it to one of the following modes:

y Quick Power Adjustment Mode <QUICK POWER ADJ>: expanding the power adjustment to 1EV step (see Section 12.1.3). Zoom (Cactus) Mode <ZOOM (CACTUS)>: controlling the zoom level of the Cactus RF60 (see Section 16.1.1). y This can be conf igured in <SWAP CONTROL>. 17.4 LCD Options The LCD screen of the V6 II can be configured in the following ways:

1. LCD Backlight Auto Off: The LCD backlight of the V6 II will turn on whenever , , the selection dial, and any of the group buttons has been pressed or turned. In order to conserve energy, there is a timer setting that automatically turns off the backlight. In <BACKLIGHT OFF>, choose from <OFF>,

<5 SECS>, <15 SECS> or <STAY ON>. 2. LCD Backlight Power: In <BACKLIGHT POWER>, configure the brightness of LCD display from 1 to 9. 3. LCD Daylight Mode: Enable <DAYLIGHT MODE> if you work under direct sunlight. The LCD screen will replace the reversed fonts with black fonts on white background. 17.5 Sleep Timer To conserve energy when you forget to switch off the V6 II after use, the sleep timer will switch the V6 to the sleep mode after a specified period. In <SLEEP>, choose from <OFF>, <15 MINS> or <60 MINS>. To wake up the V6 II from the sleep mode, press any button or turn the selection dial once. Local triggering via a hot shoe or x-sync port also awakens the V6. Note: Wireless triggering will not wake up the V6 II RX units remotely. 17.6 Work Range The working distance of the V6 II can be customized to suit your shooting purpose. In

<WORK RANGE>, choose <SHORT> when you need to place the V6 II TX units very close to the RX units (e.g., when shooting macro), or choose <LONG> for normal shots. While the <SHORT> option will reduce the maximum effective distance of the V6 II by approximately 70%, it will eliminate the interference caused by placing the V6 TX and RX units in close proximity. 17.7 Factory Reset To retrieve to the original manufacturing setting of the V6 II and erase all the custom flash profiles, use Factory Reset. In the <FACTORY RESET> sub-menu, press and turn the dial to <YES>. The screen will show <CONFIRM?>. Press to confirm. 18. Working with Cactus Gear The V6 II transceiver is compatible with the Cactus Wireless Flash RF60 series, Wireless Flash Trigger V6, V5, and Laser Trigger LV5.

(image) 18.1 RF60 Series 18.1.1 RF60x/RF60 as Slave

(image) With the built-in Cactus V6 module, the Cactus RF60x can be remotely commanded and triggered by the V6 II TX, within or beyond x-sync speed. The RF60 series in this set up would support both normal HSS and Power Sync flash. Note: The Cactus V6 II can specify up to 1/10 EV step and communicate it with the RF60; however, the RF60 series will only display the nearest 1/3 EV step. To control the power level of the RF60 series Slave:

1. Set the V6 II and the RF60x to the same channel. 2. Activate the group assigned to the RF60 Slave on the V6 TX. 3. Adjust the power level of each group as you would with the V6 RX. To control the zoom level of the RF60 series Slave:

1. Configure the swap control to Zoom (Cactus) mode (see Section 15.3). 2. In the main screen of the V6 II TX, press once. The zoom levels of the activated groups will be shown on the screen. 3. Adjust the zoom level of each group as you would to adjust the power level (see Section 12.1). The zoom control supports both single group and multi-group adjustments. You may also combine the RF60 series with TTL flashes to form a remote flash control system. For example, assign a RF60x to group A, a Canon 580EX II (with a V6 II RX) to group B, and a Nikon SB-900 (with another V6 II RX) to group C. The V6 II TX will be able to trigger them all, set their power levels in either relative or absolute power mode and adjust their zoom angles. 18.1.2 RF60 Series as Master

(image) You may assign the RF60 series as master on the cameras hot shoe and let it trigger and command other RF60 Slave and V6 II RX units. While the RF60 series Master can control the power and zoom levels of slave flashes, it would not be able to support high speed synchronization. 18.2 V6, V5 and LV5 The Cactus V6 II transceiver can work in pairs with the Cactus V6, V5 or LV5 for wireless triggering without group control. They all share the same 2.4GHz, 16-

channel platform. Since the V5 and LV5 do not support groups and remote power control, the V6 II TX will trigger all V5s, independent of which group it considers active. Similarly, both V5 and LV5 will trigger any V6 II RX, independent of which group the V6 RX has been assigned to. 19.
