Epson projector tcp / ip control help - shiney2512 - 02.09.2020
hi,
i having trouble connecting to an epson tw9400 projector via tcp /ip, i've been able get to PJ Link working (turning the projector on/ off), but i require extra commands that the PJ link doesn't support (lens control, key functions.etc)
the projector requires a handshake to enable ESC/VP.net before it will accept commands, i've been able to verify connection to the projector via the Hercules setup utility below,
this is the instructions on how to connect to the projector via ESC/VP.net, i've also attached the ESC/VP command list below
But i haven't been able to make a connection via the logicmachine
the handshake is - [i]ESC/VP.net<DLE><ETX><NUL><NUL><NUL><NUL>[/i] or HEX = 45 53 43 2F 56 50 2E 6E 65 74 10 03 00 00 00 00
and this where i'm at the moment, i've modified the Pj Link script, changing the port to 3629, but i'm not sure how to implement the handshake into the script?
any help would be much appreciated
Code:
require('socket')
value = event.getvalue()
ip = '192.168.1.64'
port = 3629
if value == 255 then
cmd = 'PWR ON<CR>' --Power On
end
if value == 250 then
cmd = 'PWR OFF<CR>' --Power Off
end
sock = socket.tcp()
sock:settimeout(1)
res, err = sock:connect(ip, port)
if res then
res, err = sock:send(cmd)
if res then
alert('Send OK')
else
alert('Send failed: %s', tostring(err))
end
else
alert('Connect failed: %s', tostring(err))

You can convert hex char codes to a string like this:
Code:
hs = string.char(0x45, 0x53, 0x43, 0x2F, 0x56, 0x50, 0x2E, 0x6E, 0x65, 0x74, 0x10, 0x03, 0x00, 0x00, 0x00, 0x00)Then you need to send it before the actual command:
Code:
res, err = sock:send(hs)
res, err = sock:send(cmd)Note that anything between <> is not a string value but an ASCII character name, so 'PWR OFF<CR>' should actually be 'PWR OFF\r'

Awesome - thank you very much for you help!

Ciao @shiney2512,
did you had to setting on the projector in order to enable TCP/IP protocol?
Thanks.
