The place to start is Epson. Find out from Epson if they offer external control by others and if so / how? Once that is clearly defined it is straightforward to send some forms of control (IP, ArtNet (DMX), RS-232, etc.). Or maybe someone on here has done it and will share. Adela

btw I looked for more info on Epson LCD H944a with no success. when asking about other products it would help if you included a link to the product

I am not sure what you are saying there. The $ character is a special character reserved in WATCHOUT string output as it is used to designate a single character hex value. For example, $0D sends the single character for carriage return . i think $24 will be replaced by just $ character.

So if you are trying to send

$(PVC:muteState)

Then you would enter 

$24(PVC:muteState)

into a WATCHOUT string cue. You may need to add a carriage return and / or line feed to the end of that string. Such as         $24(PVC:muteState)$0D$0A

To create that string cue you must define an output — go to Window - Output, add an output, give it a name like Proj1, define it as as a “network port (TCP or UDP)”, add IP address and port and then select TCP or UDP radio button at the bottom. Drag that output from the output window to a timeline to create a string cue.

Corrected hex value (24 hex = 36 decimal oops)

PVC is  name  my projector ,so my string should de 24(PVC:muteState)$0D$0A?

[RBeddig]

Maybe rather

$24(PVC:muteState)$0D$0A

As Jim explained, the dollar sign "$" is a reserved letter inside WATCHOUT. It defines that the next to numbers/letters following a "$" sign are the hex-code for an ASCII letter or a non-printable ASCII code. Other software use other letters to describe a hex-code.

The hex-code for the letter "$" is often defined as "x24" (you can find many lists and pictures on www to show you the relation between ASCII and hex-values) where "x" in this case also just tells you that the number is a hex-code.

So if you need to send the letter "$" as the first byte of your string, you have to send the hex-code instead.    $ > $24 (for WATCHOUT).

Hello, I already generated the output of the projector but in the chain it still does not respond, investigating more in the Epson manual it gives me these parameters,

The initial string they told me was $24(PVC:muteState)$0D$0A and in the Epson manual I see in shuter close and open from 0 to 63 and from 192 to 255.

What you are referring to are Artnet values, not strings sent via TCP/UDP. Different kind of control but also doable with WATCHOUT. Generate DMX outputs, connect a WATCHOUT dongle and send the values on the Artnet universe and channel which is probably explained in your manual.

Note, that Artnet control can lead to false commands since Artnet usually uses a ramp to the value you want to send. This means, if you want to send the value 200 from the current value 0, it may also send some of the values in between before reaching 200.
