SteppIR Transceiver Interface

Download latest DDUTIL

Purchase USB to Serial Converter; something like TRENDnet TU-S9

Purchase Serial Null modem cable

Open Windows Device Manager, look at Ports (COM & LTP); write down the various Com ports; these ports are in use elsewhere

Plug TRENDnet USB side into computer, other side of TRENDnet to Serial Null modem

Plug other side of Null modem cable into “DATA out” on SteppIR controller; turn on controller

Setup SteppIR  controller; “Tranceiver - Mode to KENW”; “Tranceiver - Din to 9600”; “Tranceiver - Dout to 9600”

Look at the device manager ports again.  A new port would have appeared.  The new one is the com port to the SteppIR (each time u plug and unplug the serial connection to the SteppIR controller, the com port appears and disappears on the list; it usually remains the same port number)  IF u check the port's property, u will set it will be set to 9600; from step 7 above

Open DDUtil; setup, other; on top right u will see SteppIR.  Check Enable, Check Tran Inhib, select proper com port (from step 7 above), interval set to 300, Comm setting to 9600 8N1

Put Steppir IR controller on AutoTrack

You will notice the frequency of the FlexRadio “transmit” slice on DDUtil; move the slice the frequency changes.  The steppIR will now follow this slice frequency

Have fun
