        The YoYo+ and YoYo++ are digital versions of the popular DHA Yoyo which
        allows linear movement of 1 or 2 gobos, at variable speeds, in the gate of a
        range of modern theatrical lanterns replaces traditional gobos with etched
        effects plates.
        The Yoyo combines the functions of manual control and DMX control into
        one small unit, yet gives the added functionality of being able to index the
        effects plates at a pre-determined position at any time.
        The stepper motor technology used in the Yoyo also ensures completely
        silent operation when in use, even at high speed travel.

        In the interests of safety all digital Yoyo+’s are provided with a fixing point
        for a safety chain. This must be used.

        This product is supplied for professional, indoor use by competent techni-

        Isolate from mains supply before removing any cover.

        Caution: When installed, this device will absorb heat from the lantern and
        may rapidly become hot. Allow time to cool before handling.

        No user-serviceable parts inside. Please contact DHA for further product

    It is important to ensure that the Yoyo+ fitted correctly in each lantern. Due
    to the heat from the lamp housing, the Yoyo+ should be positioned so that
    the motor housing faces towards the lens tube and not over the lamp-

    These units should not be run continuously, for long periods, at full intensi-
    ty as heat damage may result. Particular care must be taken if the lantern
    is pointing upward as this places the Yoyo+’s motor directly above the lam-
    phouse where it can rapidly become very hot.

    3       Effects Plates and Gobos

        The Yoyo+ use etched metal plates to create its effects. These plates are
        very thin and must be handled with extreme care as the sharp edges could
        be hazardous. It is also very important that they are stored in such a way
        as to prevent bending as this would be likely to lead to operational prob-
        lems in future use.
        In addition to the metal effects plates, the Yoyo+ also accept an additional
        “B” size metal gobo which slots into the holder at the back of the unit.
        These standard gobos should also be handled with extreme care and
        should be removed and replaced if they are bent or buckled.
        The Yoyo+ also has the ability to use a glass gobo when combined with the
        glass gobo effects plate. Please note that only the Yoyo+ unit can accept
        glass gobos and not the Yoyo++.
        Glass gobos are inherently more fragile than their metal equivalents.
        Incorrect use can result in an accelerated deterioration of the fine metallic
        surface and even breakage of the glass substrate. It is imperative to follow
        the guidlines below to ensure good results.

        1 ‘Flat-Field’ the Lantern
        It is essential that, prior to using a glass gobo in any luminaire, the lumi-
        naire is adjusted to produce a ‘flat field’. This means that the intensity of
        the beam is even across its whole area with no ‘hot spots’. The lamp posi-
        tion can usually be adjusted in relation to the reflector to achieve this
        result. It should be noted that the lantern will not be at its perceived
        brightest when the ‘flat-field’ position is reached.

        Failure to correctly adjust the field will produce patchy deterioration of the
        chrome surface and a build up of stresses within the gobo due to tempera-
        ture variations across the illuminated surface. In some cases this could
        cause the gobo to break.

        2 ‘Pre-Warm’ the Gobo
        In all cases, and particularly for higher wattage lanterns, it is good practice
        to ‘pre-warm’ the gobo by holding the dimmer at a low level prior to bring-
        ing the luminaire up to full power. Luminaires with discharge sources
        should be powered up (once flat-fielding has been completed) with the
        gobo installed so that it can warm up with the luminaire.
        DHA cannot accept liability for failure of any glass gobo where these
5       requirements have not been met in full. If in doubt consult DHA for advice.

    Connection of the Yoyo+ is via a 4-pin XLR type connector. The cable, which
    connects to the unit, carries both the power for the unit and the DMX data
    signal which is required for remote operation.
    This 4 pin configuration is also used by a large number of other devices
    such as colour scrollers, dimming shutters and moving mirrors, which can
    simplify the installation process and also save on the number of power sup-
    plies required in the venue. It must be noted however that the power sup-
    ply for the YoYo+ also contains all the necessary components to process the
    DMX data, and it is therefore very important to make sure that the power
    supply that you are using is compatible with the Yoyo+ (see appendix 3).

    The Yoyo+ has 2 x 4-pin connectors on its front panel (fig 1), one for power
    and data in and the other for power and data out to other units.

                   Data / Power                                  Data / Power

                                                                 Fig 1.

    Because each Yoyo+ has its own individual DMX address setting, it is possi-
    ble to daisychain Yoyo+s by linking out of one unit and into another.
    It is also possible to place a mixture of Yoyo+’s and other devices on the
    same chain (fig/2), as long as you do not exceed the total power of the
    power supply (see appendix 3).

    The Yoyo+’s have an automatic safety device built in so that if a unit devel-
    ops a fault it will automatically cut itself out of the chain to avoid interfer-
    ing with other devices.

    If a Yoyo+ is the last unit in a chain it will automatically terminate the DMX
    so a terminating plug is not required.

    It is very important that the cables used to connect the Yoyo+’s to each
    other or to the power supply are of the correct specification (see appendix
    4 for details)

5                                                                           O p e r a t i o n

    For the indexing system to work correctly and accurately the Yoyo+ needs
    to know the position that the effects plates are in at any time. To do this
    the unit performs an automatic calibration when it is first powered up; this
    involves the Yoyo+ moving the effects plates through their full length of
    travel. As soon as this has been completed normal operation will be

    During operation the unit will automatically re-calibrate itself on a regular
    basis to ensure accuracy, but this will not be noticeable to the operator and
    will not interfere with normal operation.

    Setting The DMX Address
    Each Yoyo+ has a set of 3 wheels, plus an optionwheel, which are used to
    set the DMX address of that unit. This should be adjusted using a small
    The first wheel sets the 100’s and also the stand-alone mode, the second
    sets the 10’s and the third the units.
    To set a DMX address of 24 the 100’s wheel should be set to 0, the 10’s to 2
    and the units to 4.
    To set a DMX address of 346 the 100’s wheel should be set to 3, the 10’s to
    4 and the units to 6 (fig 3).

    Power up the unit. Aiiow it to it will calibrate as indicated by the flashing
    orange LED, and then select Option 0.
    Hold the unit with the motor box at the bottom and place the effects plate
    with its attached rack into the corresponding grooves in the slides.The rack
    must be placed on the left of the unit when the address switches are facing
    Select Option 1 or 2 and the mechanism will connect with the effects plate
    and draw it into the unit.
    When the effects plate stops moving, as indicated by the orange LED ceas-
    ing to flash, reselect Option 0, the unit will attempt to eject the effects
    plate and the end of the rack will ‘bounce on the gear attached to the
    Select Option 1 or 2 and the
    effects plate will be taken in
    again and set into its calli-
    brated position (Fig 4.).

Inserting a effects plates in a Yoyo++

The routine for the Yoyo++ is identical to that of the YoYo+ except
there are two effects plates. The plates must be inserted and cali-
brated together and can only be inserted one way as there is a
guide close to the gears.

To remove the effects plates from the Yoyo+ and Yoyo++ simply hold
the unit with the motor box uppermost and select option 0. The
effects plates will fall out. The removal of plates should always be
done using the motor unit. Pulling out the gobos by handmay result
in damage to the motors.

     An internal sequencer is included as standard in the Yoyo+ . This allows you
     to program up to 60 individual steps into a sequence which can be started
     automatically every time the unit is powered up.
     Each step can hold information about all of the functions that the Yoyo+
     normally has - speed of yoyo, yoyo travel distance, yoyo position offset and
     index position, as well as an additional parameter for the delay between
     each of the steps.


     To be able to program the Yoyo+ you will need the following:

     The Yoyo+ in need of programming
     A suitable Yoyo+ power supply (see Yoyo+ user guide)
     A control desk capable of outputting at least 10 channels of DMX512*

     *Note: although it is possible to programme the Yoyo+ from any DMX light-
     ing console, it is preferable for the desk to be able to show its levels in
     binary (0 - 255) instead of percentage (0% - 100%) as this will make pro-
     gramming easier.

     Programming your sequence:

     There are a number of steps required to program the YOYO+, these are list-
     ed below in order:

     1. Enable Programming Mode
     2. Enable DMX input
     3. Set Levels and Functions
     4. Store Step
     5. Disable DMX input
     6. Exit Programming Mode

                  Programmable Sequences

Before programming, make sure that the Y0yo+ is connected to a suitable
power supply and that your control desk DMX output is connected to the
DMX input on the power supply. If all is well the Yoyo+ should calibrate
itself and then come to rest with the green light on continuously. If the
green light is flashing then there is a fault with the DMX connection and
this should be corrected before proceeding.

1. To enable programming mode you need to set the mode switch to posi-
tion 9 using a small screwdriver. At this point all the standard functions of
the Yoyo+ will be disabled and the unit should not be moving.

2. To enable the DMX input you need to set DMX output 9 on your control
desk to 93% (235-239 decimal). Without this your Yoyo+ will not respond to
your control desk. This is a security feature to stop accidental erasure of a

3. Set the channels on your console so that the Yoyo+ is where you want it
to be or is moving at the required speed in step 1. The channels are as fol-

1        Yoyo 1 index position / position offset
2        Yoyo 1 speed
3        Yoyo 1 travel distance (0% = continuous Yoyo)
4        Yoyo 2 index position / position offset (Double Only)
5        Yoyo 2 speed (Double Only)
6        Yoyo 2 travel distance (0% = continuous Yoyo) (Double Only)
7        Delay time before next step (0 - 255 minutes)
8        Delay time before next step (0 - 255 seconds added to channel 7)

Note: During programming, the channels are always as stated above
regardless of the settings of the address switches on the Yoyo+.

     The delay time is made up by adding the values of channel 7 and 8 togeth-
     er and represents the time between steps in the sequence; this can be set
     to be different for each of the steps.
     If an indexing position is set then the unit will index at the speed of the
     speed channel for that Yoyo+.

     4. To store the step, simply take DMX output 10 on your control console to
     100%. The green light will flash once on the indicator to confirm that the
     step has been stored in memory. DMX output 10 should now be returned to
     0% to enable further steps to be programmed.
     If you need to add more steps simply repeat steps 3 and 4 above, when all
     steps have been programmed proceed to step 5.

     5. After the last step, set your DMX output 9 to 0% once again, this con-
     firms that all the steps have been programmed and automatically creates a
     loop from your last step to your first so that the unit can run continuously.

     6. You can now disable programming mode by changing the mode switch to
     any position other than 9 Setting the mode switch to position 8 (playback)
     will allow you to test the sequence that you have just programmed.

     NB: Warning. Any previously stored programme will be erased when step 4
     is executed.

          P r o g r a m m i n g                          H i n t s

When creating a cue containing an index position, always give that cue a
fade time of 0 seconds. This will give you a smooth motion to the index
position. If the speed at which the index occurs is important then set the
unit into mode 1, 4 or 5 and use the speed channel to set the speed of
Fading in or out of an index cue will result in a very irregular motion of the
gobos, excessive noise and possible loss of accuracy.
