So, after all the work I put into investigating the HTTP RPC method, it turns out that the LXC-200 supports running a telnet server on a user-selectable port which communicates directly with the serial port. Select “Remote Session Method: Telnet Server” and choose a TCP port to dedicate to the specific serial port. I’m using 81 for port 1, 82 for port 2, etc. Set the “Telnet Protocol” to “Raw” as well.

To use multiple ports on the LXC, we’re going to have to use the kludge of adding multiple IP devices to our FLEX project, each with its own TCP port. I’ll start by creating a device for port 81.

In the button action, configure an Inline IP command like so:

IP ‘Aurora_LXC-200_1_Addr’ INLINE “Hello World<0d>”

After saving and uploading the project to the FLEX, pressing the button spits out exactly the data we want from the serial port. Multiple presses continue sending the correct data; there seems to be no issue with reconnecting.

So, I can now use my Aurora LXC-200 as 3 remote serial ports for the FSR FLEX-LT system.

That was easy 🙂
