Hi,

Sorry if the title isnt quite clear but hopefully my explanation will clear it up a bit.

What I'm trying to achieve is to have my software send out some data to expression and then expression can do what it needs with it.

In my head the best route is going to be to still use datalinq for this so that covers getting what data I want into expression.

The part that I wanted some info on was that, I can't see a data linq source that lets me send stuff to data linq. They all seem to be data linq checking on a file/db/webapi (where datalinq does a get from the api. ie the RSS data source).

What I want in a perfect world is for data linq to expose a tcp port or something like that, that allows me to send data to datalinq. My assumption is that if this was to work that it would require some kind of schema first so it knows what data to be expected and how it can then expose it back to expression.

If a built in data source that can achieve this doesnt exist, has anyone got any experience or knowledge about whether its possible to implement a custom data source?

Any thoughts on this or suggestions would be greatly appreciated

Thanks

Hi Dave
You could use Dashboard as an intermediary, with a TCP listener, and throw all the data that comes in out to a parameter that gets picked up by Datalinq and then onto XPression,.
But I would second having a generic TCP connection on Datalinq that allows for completely custom data to be sent to XPression. Or make the protocol used by Dashboard to Datalinq known as that would probably provide the solution.

#XPression

XPression Datalinq Server has an ASCII datalinq source that allows it to parse a custom ASCII data string over TCP/UDP/SerialRS232. You should be be able to update the string at regular or irregular intervals. You could keep a series of fields updated on the Datalinq server this way.
#XPression

ASCII datalinq source was added in version 5.1 and will accept up to 4095 bytes.
