I have a Zero-88 Jester ML24 lighting controller. It gets used for local charity and non-profit shows.

I suspect there is an internal fault with how the faders are multiplexed. The most obvious fault is that the Grand Master fader will only go to 75%, but operating other faders will make it go to 100% as they get to full travel. In test mode, the flash buttons work correctly, but the associated fader will not be 'read' correctly, however another nearby fader will operate in place of the desired one.

There is a new battery installed, the desk has been reset and the last available firmware and fixture library installed. I've made up and tried a new ribbon cable assembly in case the original was faulty.

Is it possible to get internal schematic diagrams for this desk so I can get busy with a 'scope and meter?

Thank you.

Here is what i want One Cue that will snap fade one light and slow fade all the others.

Is it possible to do these multi-fades on one cue?

Thanx and Cool Yule

Thank you

The Pre-set Setup Mode is not working for some channels only but working for every thing else and every mode.

(P.S. Sorry if this has been asked before but the Search facility here did not bring up anything useful)

The issue is when I turn on and boot up the desk, the main LCD is blank (but still backlit), same with the wheel LCD. The top MFK lcd is showing content, but slightly malformed on the top row (see pics below). Bottom MFK lcd seems fine so far.
This issue sometimes happens when I turn the desk on, and sometimes doesn't happen. DMX output still works fine, same with monitor VGA output from the back ports. Buttons all still work, so do the wheels, as the red LEDs in the buttons do change when I press them to the desired option I want to select. It's the LCDs that are the issue.

Another thing to add is that on the top MFK lcd, when I select either Colour, Beamshape or Position, the four horizontal bars you see disappear and it just goes to how picture E shows.

• Picture A: Whole desk view
• Picture B: The MFK LCDs
• Picture C : Main LCD
• Picture D : Wheel LCD
• Picture E: four horizontal bars have now disappeared after selecting C, B or P

Pictures are attached below. If anyone knows the problem here, I would be incredibly grateful if you could help me. Thank you. Perhaps it is a loose connection inside, but maybe something damaged? I'm not sure. I wanted to be careful and not open the desk just yet in case something goes wrong.

I have bought a pair of 19x15 LED Moving heads from Amazon 2Pcs 19 LED 285W Wash Zoom Moving Head, RGBW 4 in 1 Professional Focus Dye Stage Light with Light Strip and 4 Control Modes for Party KTV Concert Music Festival Christmas Wedding Celebrations : Amazon.co.uk: Musical Instruments & DJ and I have created a fixture for it using the Zero88 software but my Jester 24 ML is not recognising the file type when I attempt to update the library. Any suggestions?

Thanks,

Tim 

just for info; If your console starts with only 24 channels, and the other 24 always remain lit then:
Open the console and check the dipswitches
-preset 1-12 must be: 2 ON, 1&3 OFF
-preset 13-24 must be: 2&3 ON, 1 OFF
Otherwise Check the ribbon cable connections

For my part a dipswitch (13-24) was not in the right position.
Thanks to the zero88 support team (entertainment@signify.com)

New to the forum and just posting to see if anyone might be able to help...

I use a Jester ML48 and have just purchased a couple of Martin ERA 150 Wash lanterns.

Previously I've just requested a new file for new fixtures not on the list (I have the last update installed).

However, my email request this time was met with a polite reply that included a file for FLX desks, which unfortunately doesn't help with my older desk.

Just wondering if anyone has already created a file for the Jester for this lantern - I have had a look at the fixture editor tool, but it is pushing my limited tech knowledge and ability and I'm not confident I can successfully create a new file that will work...

Thanks!

I recently bought a second handed Jester48MI.

After programming the submasters, I used it for about a month always in run mode until, all of a sudden, the buttons below the faders stopped working all together.

Do someone knows if there's something i might accidentally have done ? 

Thanks in advance for your attention and support.

Meanwhile I've found the product sheet. 

Maybe you can help me with this referral. 

This is still to run on our Jester 48ML. 
The board is great. I love it. 

Thanks.

I will need to lern how to operate the board and will struggle in programming fixtures. 

In our theater we do only have very basic LED lights, some washers and PARs. 
I assume, that the library that comes with the Jester has some generic LED fictures to assign, is that right?

Another question: will the Jester be working properly with the latest update 4.1 or will I have problems in the very next future?

I also found a reference that this board can be programed remotly by a PC. Is this software still available and will it run on most recent windows systems?

Thank you

I have worked here for several years and it has worked well, but its now been brought to me with an Error 001, I have followed a few threads in here and done a few basic things, I have replaced the internal battery, I have downloaded and extracted and ran the .Jos file and everything seemed to work correctly, pressed enter and I am back to where I was before, the error comes up, before i done the battery change and update hand I was getting weird text on the screen but now the enter button wont take me out of the error message.

ill add another couple of images, any help would be greatly appreciated

The handbook under "Presets in Run Mode" indicates we should still be able to Flash channels on Preset A. You can still raise channels on the fader as expected.

I have been unable to determine if this propblem is due to a setting being wrong somewhere in the desk or if the desk has developed a fault. Advice please.

Have been trying to patch a 10 channel Parcan onto a Jester ML24 and to some extent this works as when I exit the set up mode I can edit the light with the function keys colour brightness ect. However I have 6 other lights that I can fade on and off from the preset A faders, how can I add this new light to be on fader 7?

When I go into the dmx patch, with the light patched in at 70 I can only set the number 7 fader chanel to either 69 or 81. I have also done the inverse setting the channel fader to 70 and the Light to the next closest dmx channel up but this too doesn't work. 

For the 6 other lights that have been already programed before, they are also 10 channel, with for example light 1 is set on the patch channel dmx 1 and the patch fixture to dmx2. 

Hope this makes sense 

Many thanks 

Tom

Many thanks

I have been having some issues adding new fixtures to my Jester ML24, and so was wanting to buy a cheap Par Can -Equinox MaxiPar Quad LED Par Can to test a few things out. However when looking on the fixture library, I realise that this light is not on the list. I there a way of adding it? 

Many thanks 

Tom

All the LCDs on the flash buttons are lit constantly on channels 1-6 on banks A and B, and none of the faders appear to do anything. With a bit random button pressing I did get it working in a chace, and the Master fader worked then, but that's the only time I saw any of the lights come on.

I tried a desk reset and it didn't make any difference. I have until Sept 5th when the schools go back to get it working! Any suggestions gratefully received!

I have a Jester ML and a Jester TLXtra to dispose of. I have not been fortunate enough to find a buyer even at near give away prices. Is there a way of recycling old desks? 

I tried to sell them on just before the pandemic but of course nobody was buying. Any advice would be welcome.

Thanks,

Terry

i am currently searching for a Jester 24/48 Desk for my school in Germany. We already have a Jester 12/24 one, but our setup has grown since we have bought the jester 12/24 and are now in need of a bigger one. It needs to be from the jester series because many of our teachers and students are already familiar with it's software. Do you know any contacts who are selling a jester 24/48 right now?  

can everywhere help me ?
