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? Let’s 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. Do not dissemble.
7. Do not crush and do not expose the V6 II to any shock or force such as
hammering, dropping, or stepping on it.

7. 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:
zCanon e-TTL
zFujifilm TTL
zNikon i-TTL
zOlympus / Panasonic TTL
zPentax 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

10. Camera System: Auto-detect and Learning
To fully utilize the advanced features of the V6 II transceivers, it is necessary to
configure the correct camera system profile to the V6 II TX. On the LCD screen, the
different camera systems will be represented by the icons below:
Canon (Canon Camera Logo)
Fujifilm (Fujifilm Camera Logo)
Nikon (Nikon Camera Logo)
Olympus / Panasonic (M43) (Olympus Camera Logo)
Pentax (Pentax Camera Logo)
10.1 Auto Detect
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).
On the V6 II LCD screen, the configured flash system will be represented by the icons
below:
Canon (Canon Flash Icon)
Fujifilm (Fujifilm Flash Icon)
Nikon (Nikon Flash Icon)
Olympus / Panasonic (M43) (Olympus Flash Icon)
Pentax (Pentax Flash Icon)
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 camera’s 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 camera’s 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.
2. 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.
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:

When setting up the absolute power mode, the V6 II TX will collect the flash profiles
being selected by the RX units in the same channel and rescale them to the unified
light intensity scale. The following example shows how the model-specific relative
power scales are translated into the absolute power scale.

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
determine whether they produce the same flash output.
6. 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
when switching on again.
2. 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 camera’s 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.
14.1 Setup for Multi-brand
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 camera’s shutter is now in a continuous open
state.
4. To close the camera’s 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 camera’s hot shoe, and also connect the V6
II RX to the camera’s 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.
5. 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.
(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).
16.4 Group Sequence
There may be some situations in which you would like to f ire the slave groups in a
very short sequence:
yPost-production of high dynamic range (HDR) photos: In burst mode,
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.
yEvaluating 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.
ySpeed 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:
yQuick Power Adjustment Mode <QUICK POWER ADJ>: expanding the power
adjustment to 1EV step (see Section 12.1.3).
yZoom (Cactus) Mode <ZOOM (CACTUS)>: controlling the zoom level of the
Cactus RF60 (see Section 16.1.1).
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 camera’s 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.
