• The EV-Controller is compatible ONLY with

Ikelite DS Substrobes.

• Set the strobe in the TTL full-power setting.

• Adjust the EV Selector Dial on the EV

Controller to manually set the strobe output in

half-stop increments.

• The EV-Controller is automatically turned on

and off as the strobe is turned on and off.

• No battery is required in the EV-Controller as

the strobe powers the controller. The power drain

on the strobe is negligible.

• The EV-Controller features a built-in slave

sensor allowing the controller to be triggered by

the flash from another strobe, or a sync cord can

be connected to trigger the controller.

• Reference the visual ready light on the strobe

for indication when the strobe has recycled and is

ready to fire. There is no ready light indicator on

the EV-Controller.

• For balanced lighting between your subject

and the background, meter the available light and

set the camera aperture accordingly.

SSEELLEECCTTOORR SSIITTCCHHEESS

The EV-Controller features two selector

switches (camera PP-- PPand strobe 125-50)

concealed behind the removable switch cap

located on the back of the controller. Set each

switch in the appropriate position.

OOppeenniinngg tthhee SSwwiittcchh CCoommppaarrttmmeenntt

Make sure the EV-Controller is dry before

opening the selector switch compartment. Use a

coin to unscrew the switch cover counter

clockwise. Note the position of the o-ring around

the perimeter of the cover. Keep the o-ring and

sealing surfaces clean. Lightly lubricate the o-ring

with silicone lubricant provided. Never use spray

lubricant as it may crack the plastic.

After adjusting both camera and strobe

selector switches,

use a coin to secure

the cover and

hand-tighten to

assure the proper

o-ring seal.

Set the camera switch to indicate whether

preflash is present. A separate camera

information sheet states whether or not each

camera features preflash.

PP- No preflash

This "no preflash" setting instructs the slave

sensor to trigger the strobe every time it senses

the other flash firing. Choose the "A-no preflash"

setting when using an optional sync cord.

PP- Preflash camera

This "preflash" setting instructs the slave

sensor to ignore the first flash (preflash) and to

trigger the strobe when the second flash (main

flash) fires from the other strobe. The sensor

will reset if no second flash is detected.

It may take a few test shots to become

familiar with the use of the EV-Controller. Use

the EV Selector Dial on the controller to increase

or decrease the flash exposure.

ith a digital camera, one may choose to

evaluate the exposure of the subject on the

camera's LCD screen and adjust the power

setting of the EV-Controller based on that visual

exposure evaluation.

GGuuiiddee NNuummbbeerr

The alternative method in adjusting the EV-

Controller is to determine the power setting

mathematically based on camera aperture and

subject distance.

Multiply the camera aperture (f-stop) by the

camera-to-subject distance, and the resulting

value is the underwater guide number used to

reference the suggested EV (exposure value)

setting for the controller. Note that the chart

is based on a camera set to ISO 100.

The EV Controller may be used in a couple of

different ways. With a digital camera one may

choose to evaluate the exposure of the subject on

the camera's LCD screen and adjust the EV

Controller based on that evaluation.

Some people like to go by the numbers. The EV

Chart will allow those who desire to calculate the

recommended EV setting based on camera

aperture and subject distance.

The EV Controller chart is a guide to aid in

determining the Exposure Value setting. To

determine the EV setting you need to calculate

an underwater guide number. Note that the chart

is based on a camera set to ISO 100. To calculate

the underwater guide number, multiply the

camera's aperture (f-stop) by the camera to

subject distance. The resulting number is the

guide number used to reference the EV Setting.

Example:

Using the DS50 Substrobe with the camera's ISO

set to 100. If the camera's aperture (f-stop) is

set to f-3, and the camera to subject distance is

4 feet, aperture (3), multiplied times the distance

(4) equals 12. In the chart under DS50 in the (ft)

column find guide number 12.

The recommended EV setting would be -2.5.

GGuuiiddee NNuummbbeerr EExxaammppllee::

Using the DS50/51 strobe with the camera's

ISO set to 100. If the camera's aperture (f-stop)

is set to f-3 and the subject distance is 4 feet,

then the aperture of 3 multiplied times the

distance of 4 equals a guide number of12. In the

chart under DS50/51 in the (ft) column, find

guide number 12. The recommended EV setting

would be "-2.5".

MMOOUUNNTTIINNGG

The EV-Controller clamps to the stem mount

at the base of the Ikelite strobe arm. This is the

same stem mount that snaps into the quick

release handle secured to the camera housing.

Position the controller with the cord pointing

up. Loosen the mounting knob on the controller

by rotating it counter-clockwise, and insert the

stem mount of the arm thru the clamp opening

on the controller.

The controller can move up and down and

also rotate 360° to properly position before

tightening the knob to secure the controller.

CCOORRDD CCOONNNNEECCTTIIOONN TTOO SSTTRROOBBEE

The short cord extending from the EV-Controller

connects to the female bulkhead connector on the

Ikelite DS Substrobe. This short cord is NOT

removable from the controller.

DDOO NNOOTTuse the controller with other model

Ikelite TTL Substrobes or another brand strobe.

The connector threads are very fine; DDOO NNOOTT

cross thread. If it is difficult to turn, you are cross

threading.

1. Turn the Substrobe OFF and make sure all

components are dry. Clean and lightly lubricate

the stem o-ring and the bulkhead connector

threads. Check o-ring for nicks or cuts. Never use

spray lubricant.

2. Note the positioning of the receptacles and pins.

Properly align the end of the cord on the

controller and insert into the bulkhead connector.

3. Hand-tighten the knurled retaining ring on the

cord. Push the connector body further into the

bulkhead connector and continue to tighten the

knurled ring to secure the cord.

DDOO NNOOTTremove the cord from the strobe

underwater or when wet. Connection is NOT

waterproof when disconnected.

DDOO NNOOTTleave the cord connected for prolonged

periods. Otherwise, the cord may freeze to the strobe.

After each dive, disconnect the cord and lightly

lubricate the connector threads.

Never use spray lubricant.

BBUULLKKHHEEAADD CCOONNNNEECCTTOORR

The EV-Controller features a female Ikelite

bulkhead connector, which is sealed by a

removable waterproof cap.

This bulkhead connector permits different

Ikelite sync cords to be connected between the

EV-Controller and select camera systems. The

optional sync cord relays the trigger signal when

the camera shutter button is depressed. Note

that the camera housing MUST feature an Ikelite

or Nikonos bulkhead connector to use the

optional sync cord.

The removable waterproof cap seals the

bulkhead connector on the controller when the

optional cord is not used. The bulkhead

connector must be sealed to remain waterproof.

Refer to the prior "Cord Connection" section

of this instruction manual for the proper

procedure to connect the optional cord.

DDOO NNOOTTremove the optional cord from the

controller underwater or when wet. Connection

is NOT waterproof when disconnected.

DDOO NNOOTTleave the cord connected for

prolonged periods. Otherwise, the cord may

freeze to the controller or camera system. After

each dive, disconnect the cord and lightly

lubricate the connector threads.

Never use spray lubricant.

TTEECCHHNNIIQQUUEESS

The purpose of a strobe is to illuminate the

subject and bring out the subject's true colors.

Due to the loss of color when light passes

through water, move in on your subject to

photograph thru as little water as possible. The

maximum recommended lighting distance with

ANY STROBE underwater is about 2m (6').

For balanced lighting between your subject

and the background, meter the available light

and set the camera aperture accordingly. A

narrower aperture darkens the background. A

wider aperture lightens the background.

AADDDD AA SSEECCOONNDD SSTTRROOBBEE

Avid photographers often add a second

auxiliary strobe positioned away from the

camera lens for more natural lighting. hen

using two strobes, choose an EV-Controller for

each strobe to manually control both flash

outputs.

To trigger the second strobe, use either the

built-in slave sensor in the EV-Controller or

connect an optional dual sync cord to both

strobe/controller systems. The slave sensor in the

controller enables the strobe to be moved freely

and positioned virtually anywhere.

VVIISSUUAALL IINNSSPPEECCTTIIOONNSS

Visual inspections are important. Take the

time to visually inspect the system above water.

An improper seal or a loose connection can cause

a lot of damage. Always check for leaks once you

place the system in the water.

it does not cover customer neglect.

BBAATTTTEERRIIEESS

Always carry spare batteries. eak batteries

cause many camera and strobe problems. It is

possible to buy bad "new" batteries; check the

voltage output with a meter.

NNoo bbaatttteerryy iiss rreeqquuiirreeddin the EV-Controller.

The DS Substrobe powers the EV-Controller, and

the power drain on the strobe is negligible.

MMAAIINNTTEENNAANNCCEE

The Ikelite EV-Controller should be given

thesame care and attention as your other

photographic equipment.

1. Always rinse the exterior of the EV-Controller

and Substrobe with fresh water after use.

Make sure the cord is connected between the

controller and strobe for the proper

waterproof seal, and make sure the separate

female bulkhead connector on the EV-

Controller is sealed as well. The units can be

cleaned by soaking them in a mild soapy

solution. Use liquid soap; RINSE and DRY

both before storage.

2. Keep the switch cover o-ring and threads

clean and lightly lubricated. Keep the sync

cord o-ring and threads clean and lightly

lubricated. DDOO NNOOTTleave the cord connected

to the strobe for prolonged periods as

electrolysis can make removal impossible.

3. ith exception of the switch cover, the EV-

Controller is factory sealed. DDOO NNOOTT

disassemble the controller.

LLUUBBRRIICCAANNTT

Silicone lubricant is provided. Use only

enough lubricant to lightly cover the o-ring; wipe

off any excess with a clean cloth. Lubricant only

reduces friction; it is NOT a sealant.

DDOO NNOOTTuse spray lubricant as it may crack

the plastic.
