Updating DCS USB to Serial

Just add the serial cable and you should be set.
Some folks have had difficulty with the usb to serial adapters.
Watch your port # as I suspect that is the issue.
We noticed at work that the usb adapters there would only work once per computer boot up talking to a controller we make.
Odd things happen with usb.

Hi TheBigT,

1. Yes, you can use a USB/serial adapter with Win7-64. I highly recommend the Gigaware apapter from RadioShack - #26-949. Several of us on the forum have been using this particular adapter on various OS/DCS hardware combinations.

2. Only the latest Rev. L TIU's can be directly programmed with USB. All earlier TIU's need to be programmed with an RS-232 serial port. Since computers don't come with serial ports anymore, the USB/serial adapters are a good work around. There are also PCI cards available to add a native serial port to a desktop computer.

3. That's all you need for the updating the TIU. You will also need a telephone handset cord (different from the wall cord) to update the remote.

Dave/Russel,

Thanks for the information and help. Three day weekend seems like a good time to update.
