RossTalk is a simple IP-based control protocol used by many of Ross Video’s products.
Helm doesn’t have a specific RossTalk driver, but it’s very easy to issue RossTalk commands using Lua scripts.
RossTalk devices listen for incoming commands on TCP port 7788.
First, establish the TCP connection – either in the Panel’s OnStartup script, or just before sending the command.
local socket = require("socket") local host, port = "127.0.0.1", 7788 -- Replace IP Address here rosstalk = assert(socket.tcp()) rosstalk:connect(host,port)
You can then send commands – which must have a “\r\n” sequence at the end to send the required newline sequence.
Here’s the panel shown above, which controls the XPression sequencer.
