Yes you can. You have to load the most current DCS loader onto your computer. You have to have the correct cables. Is your TIU an older version or does it have the USB port?
You download the software from that MTH link above. You connect the cables and the TIU to the computer and click download. It will do the rest. You have to have the correct drivers in your computer.
You then disconnect the stereo jumper cable, connect the 4 wire handset cable to the remote and the TIU's remote jack, and again load the software, this time into the remote. The biggest thing there is you have to depress the power button on the remote and hold it when instructed to do so. There have been posts about using a clamp. I just hold it myself.
Here's the DCS loader app and the instructions for all this:

You can also contact your local service station to do it for you. (or a local DCS friend?)
