Hi to Every one in this Forum. I noticed that here are some experts in the matter and I would Like to make you a question because i'm deseperated...
I have a Daktronics Screen (model PST-12HD) that I bought last year... used one. Here in my country (PORTUGAL) we do not have any representative or any assistance of Daktronics which make even difficult things for me.
As you may all know the screen "only" works with its Video processor which converts the video signals to a labeled VMAX format. The a called Data Distributer (DD) receives this VMAX signal from the video processor and transmits the signal to various Multilines Controllers (MC) that are connected to several screen panels.
My question is if there is ANYWAY of working with this display without the original DD or MC and use those generic LYNSN sender/receivers cards, using LYNSN Led Studio Program to play video in the screen?

Please someone that helps me on this... Kind Regards to all.

BTW if you are interested I can point you towards a descriptor for '0042100000' and all the other message headers

Are you sure that the messages ended in **EOT** <checksum> **ETB** ? A standard message format that started with **SOH** **STX** would more likely end with **ETX** <checksum> **EOT**

Anyone tried reading the signal for the J2 and J3 ports of the Omnisport 2000? I'm looking for clues on what to send to the Daktronics display from our own timing system.

If I remember correctly it was a 115200 baud serial line. The data being sent depends heavily on your scoreboard configuration though.

I think you were sample J5, the RTD port. Do you know if the message formats send over the J2/J3 ports are the same as sent via the J5?

They are different, I remember trying to debug the J2/J3 ports first but found it gave data in a less readable format than J5. May need to stick a oscilloscope on there and see what you can decipher. IIRC, J2/J3 sent RS-232 voltage levels at 115200 baud.

I have a bunch of questions I'd like to ask you offline. I couldn't find an email contact for you. Would you mind pinging me at william.ferguson@xandar.com.au?

Hey! I just sent you an email William. Its regarding the J ports on the back of the controllers. My school has an all sport 5000 thats missing the serial port, so i'd like to interface with that if possible. Let me know if the email you listed is still good to contact you. Thanks!

The RS232 information for the RTD is located on the 25 pin port J6 on the all sport 5000 (pin 3 for RS232 TX+ and pin 7 for RS232 GND). There is a port expander available from serialtools.tv that allows the DB25 passthrough and DB9 connection for ease of connection to a serial port

I dont "need" the serial expander though, correct? Cant i just use a DB-25 to DB-9 adapter to get the serial data? Thats what i heard of many doing but wasnt 100% sure

Yes, a DB-25 to DB-9 adapter will work

Great work. Pinout for All Sports CG is tip to 8 ring to 9. Cheers

I am looking for the 'pin-out' information for the All Sport CG cable running from the AllSport controller's J1/J2/J3 port (1/4" phono) to the DB9 connector on the CG. Which of the two phono wires go to which two pins on the DB9?

This gives me a good starting point for our Allsport 5000 system. thanks!

Did you have any progress on your Allsport 5000? I'd be happy to collaborate if anyone wants to hit me up on Twitter.

I haven't done much with this as I've been waiting for for our video upgrade to finish. I'd love to collaborate on this though.

Cool. Anyone else who is interested, I've set up a repo at https://github.com/JoshuaCa... and I've also linked a Gitter chat there so we can chat and share results. I'm getting my school's AS 5000 this afternoon, so I'll connect to the serial outputs, capture the data, and post it to the Gitter chat so we can start pulling it apart. Theoretically we could add other scoreboard controllers as well.

What CG software are you guys using? I would like to do something like this with Track and field. Any experience integrating with finishlynx?

Fantastic! Huge help! I am very thankful.

Great work! Thanks for sharing your findings! I've linked to your article on my blog post: http://thetechnologyteacher...

The details are well-explained and very concise.
