hello

i have one of these signs and it has just stopped responding to sigma 3000 – gives “connection error” when trying to connect. It is still responding to ping at the correct IP address and nmap will return it’s MAC address (and Manufacturer, Chainzone Technology Co). I’ve contacted Chainzone but they haven’t responded. Any ideas whether there is a way to factory reset?

I am having some problems, namely my sign still has a 169.x.x.x ip address. You said you had success changing it. Um, how can you change it? I haven’t found a way. The sign did not come with any software. The instructions said to install some though.

I have a 40″ LED that I have created a VB.net app using the JetFileII.dll and can send messages to the LED without issue. However there is a limit to how many bytes that can be sent to the sign at one time. What I cannot figure out is how to name the file that is being sent over to the sign. I would like it if I could send over multiple files so there are more play lists and then allow them to play.

If you have any success doing this please let me know.

Hello,

A follow-up about playing multiple messages that are updated randomly.

We are developing a product based on this display and we’ve found the settings that allow a series of messages in RAM being played one after the other and not requiring any playlist to be generated/updated.

Using the Sigma Play software, in the System Set screen, the relevant settings are:
- Play mode: play immediatly
- Initialization schedule: scheduled mode

In the Default display settings window:
- default partition: E
- pause: 0
- save playlist: C

And this is it. Just update the messages in RAM partition as neede and the display will show them one after the other.

I have a VB6 program that I was successfully using with a 4U2SEE display. I was using UDP protocol from my desktop PC through my LAN. I tried using the same program from my laptop with no success. I am going to try and use TCP protocol to see if that works. I wonder what setting could be different between my desktop and my laptop.

I am wondering if anyone here can or already has a VB.net or VB6 working example. There is one in the latest sigma zip file from favotech’s website however the entire thing is in chinese and it makes it quite hard to understand.

Ideally what I would really like it an application that would read a text file and send that to the sign.

Any help would be greatly appreciated.

I managed to solve the problem with SEQUENT.SYS. In other words, I can upload my own SEQUENT.SYS file now from php.

I made a simple php library for my sign, it is available at http://www.mediakum.com/phpledsign/. I used it with my Eurostile ESN sign, but it will likely work also with these 4U2SEE signs.

This blog and its comment have been quite useful in developing that library, so thank you all!

Hello there, EXTREMELY, interested in your work. I have a similar spec sign that also uses the jetfile protocol, so I have made it my goal to communicate to it in as many languages as possible. First one, is to do it in PHP. Once im familar more in my native grounds there, I’ll have a try and going to C#.

While researching this sign, I have written some docs in more english than the jetfile spec pdf you’ve originally linked too. Get in touch on my email

Oh, although I’m working on making it more dynamic, I’m trying to get a proof of concept working. In php, I deteremined the socket_connect is overkill. so I went with fsockopen() in udp mode. Remember, UDP is what these signs use. And also, from the stock config, you need to load sigma editor and turn on some settings to make them play nice to being plugged into a router (otherwise you need to plug into your pc directly).

Anyway, A line of code to send a hardcoded, direct message in theory is:
$msg = Chr(0×01).”Z11″.”Chr(0×02).”ETAA”.Chr(0×06).Chr(0x1B).”0b”.Chr(0x1C).1.Chr(0x1A).1.”Test to display”.Chr(0×04) ;

Notes: chr() is used to have a hex charecter, ETAA – Is the location of the file, ET is the location, AA is the name.

Like I said though, would be interesting to get in touch!
