GENERAL INFORMATION
The RT-2 is a 2-Tone decoder module that is capable of decoding up to 3 different 2-Tone sequences. The RT-2
offers momentary and latched outputs and supports individual and long tone group calls from 275 to 3500 Hz.
KL-3 PROGRAMMING
Midian’s RT-2 is programmed using the KL-3 or a 12-button row/column keypad. For keypad programming see
the Keypad Programming section below. Please reference the KL-3 manual for setup instructions of the KL-3
software and hardware. From the product selection screen on the KL-3 software, select the appropriate product
name from the list and click OK.
Set the parameters of the product to fit the application. If any clarifications on a feature are required, move the
mouse cursor over the feature name until the question mark appears and right click, a definition of the feature will
be shown.
After entering the parameters, save the file by going to File - Save As. Enter the file name in the File Name block
and click Save. Saving the file will allow for quick and easy reprogramming of units.
Connect the Orange/White wire to the Green KL-3 lead and the Black wire to a common ground with the KL-3’s
Black lead. The Yellow clip lead is not used with these products, as the RT-2 is non-readable.
Ground the PTT Input (Gray Wire); turn on power, and within 5 seconds click “Program Unit” in the menu bar to
send the file to the product.
