[Epsonprojector] TCP/IP connection handshake needed

[tbraune42]

Epson Projector is not working over TCP/IP due to missing handshake. see kb.epson.eu 7914: How to Send ESC/VP.net Commands to a Projector

To connect to port 3629, initial must send the code: "45 53 43 2f 56 50 2e 6E 65 74 10 03 00 00 00 00 " To the projector to respond to requests.

The corresponding code could be inserted in the EpsonProjectorTcpConnector.java code

declaratiion:
String handshake = "ESC/VP.net\0x10\0x03\0x00\0x00\0x00\0x00";

in the coonect() procedure after line 53:
out.write(handshake.getBytes());
out.flush();

Unfortunately, I'm too stupid to compile this myself and upload it to git.

@tbraune42, binding doesn't currently support Epson TCP/IP protocol, but serial protocol directly or via TCP/IP link. So current TCP/IP support just make possible to use serial port / TCP converters.

[tbraune42]

but if you just add my suggestions it should directly work. because the whole tcpip routines are already implemented. there is no difference between ESC/VP and ESC/VP.net and the ip code is already implemented in the bundle. only the correct "handshake" is missing in the code.
and if you want support ether serial and tcp2serial adapter, you could e.g. add a new value the the config file (let say handshake) where we can insert the handshake code. (if handshake != null send handshake) in the connect procedure.
it make no difference if the ip recipient is a tcp2serial adapter or an epson projector (expect the handshake)

so i did some quick and dirty coding and as expected it is possible to direct connect to the projector with a little changed is EpsonProjectorTcpConnector.java.
sadly i am not able to run the epsonprojector binding directly in eclipse. is there a "Special" tick to do that? otherwise i would like to change the code accordingly and upload it to git. any clue, why i can not run this binding in eclipse? i have enabled it in to run config of course

[tbraune42]

I have come a lot further here and will now adjust the binding accordingly. Maybe this is still interesting for other people.

Hey, I was wondering if you've made any progress on this? I have an epson home cinema 1060 projector I would also like to control via IP (as it has no rs-232 port and is wifi only). unfortunately I don't have the skillsets to make the changes you mention, do you think you could walk me through it? All I wish to accomplish is to know the current state of the projector (on or off) and be able to turn it ON or OFF via openhab. I'd really appreciate it.

please see here. https://github.com/tbraune42/compiled-addons
you have to manually install this addon
please use port 3629 in config file

Thanks, Ill give it a try when I get home this evening

[l1t7l3ph0o7]

Can you please post an example of a valid config file? I'm having trouble understanding what to put in there, In the documentation there is only info for serial connections, Do you happen to have any documentation?

[l1t7l3ph0o7]

OK, after a bit the config file auto generated I put in my configuration, but I get these warnings:
`2018-08-25 22:31:19.950 [WARN ] [ector.internal.EpsonProjectorBinding] - given config key 'localtime' does not follow the expected pattern '.<host|port>'

2018-08-25 22:31:19.953 [WARN ] [ector.internal.EpsonProjectorBinding] - given config key 'password' does not follow the expected pattern '.<host|port>'

2018-08-25 22:31:19.961 [WARN ] [ector.internal.EpsonProjectorBinding] - given config key 'user' does not follow the expected pattern '.<host|port>'`

And I have no control

My config looks like this:

LRProjector.host=192.168.137.17
LRProjector.port=3629

And my Items:
Switch EpsonPower { epsonprojector="LRProjector:Power:60000" }

It's about time to take this discussion to a discussion forum.

Thanks @tbraune42 your patched version works fine. Why don't you want to submit this as PR into main branch?
