Telnet communication with Biamp Tesira - Martin Rogstad - 29.10.2020

Hi,

I have a project where we need to control source and volume level on a Biamp Tesira system from a KNX display.
This involves communication via Telnet.

I tried to search for similar solutions in here, but only found something for Denon.

Is there anyone here who can show me how to open a Telnet session with this system?

If anybody want to take this scripting job for me, please let me know.
I am now familiar with advanced scripting.

Hi,

Try this:

Code:
local host, port = "192.168.2.60", 23

local socket = require("socket")

local tcp = assert(socket.tcp())

tcp:connect(host, port)

tcp:settimeout(0.5)

--Set command

command = string.char(0xFF,0xFD,0x01) -- Do Echo

-- Write command 

tcp:send(command .. '\r')

--or try Write command

--tcp:send(command)

--Get Reply

local s, status, partial = tcp:receive()

--Check if reply has a value

if s then

    --Do your action(s) with replies

    if s == string.char(0xFF,0xFC,0x01) then

     log('Wont Echo')

    end

    loghex(s)

end

tcp:close()

BR,

Erwin
