Type 3: Mini (TRS) to 3-pin captive connector cable: The mini (also called TRS) connector is less
commonly used; it appears on some controllers for 
the consumer electronics market. Here are the pin 
configurations: 
 
Tip = Tx 
Ring = Rx 
Sleeve = Ground 
 
Note: please connect the pins with the identical 
names of the Luxi 3-pin captive screw plug. 
A female mini is shown in the picture. You’ll need 
another common mini to mini audio cable to 
connect this cable to the host. You can also use a cable with male mini plug and terminate the other 
end with captive screw plug and only use this one cable for the connection. 
 
 
Once the cable is ready, next is to install the terminal software. There are many terminal software 
available, like HyperTerminal, or Docklight. We’ll use Docklight here as an example. This is a freeware 
that can be downloaded here:

Here’s the startup screen of the Docklight; choose OK for a free trial usage.
