USB Interface - Read Me First

FYI: Manually installing drivers is usually not needed under windows 7 or 10. The usb board is plug and play as long as your PC is connected to the internet. Do not attempt to use Windows XP, Vista, Windows 8 or 8.1. These OS versions are not reliable enough for JMRI and USB usage. 

If you have already installed JMRI, completely remove it from your computer before proceeding. Then turn off your computer.

If the USB board came with the jumpers already installed, remove all the jumpers and set them aside. Do NOT discard. 

Turn on the Power Cab in the normal fashion by connecting the Power Cab using the flat 6 wire cable to the left side of the Power Cab Panel (PCP). Wait for the red light to come on the panel.

Connect the usb interface to the right side of the Power Cab Panel (PCP) or the rear of the panel. Any NCE cab bus cable can be used, a flat 6 wire or coiled 4 wire.

Using a standard USB Printer Cable (not included), connect the other end of the USB board to your PC.

Turn on your PC.

After you have logged in and the PC has completed booting up go to the Windows control panel / device manager. Look for a section labeled "Ports" Under ports You should see a listing for Silicon Labs CP210x. Make note of the COM port being used.

To get more information, double click on the item for the Properties window.

You can now instal JMRI or your other choice of software. Remember the COM port number the USB board is using as well as the speed settings. The COM port settings in the Windows Device Manager and JMRI MUST MATCH 100% of you will not get correct communication. Note* - FAQ - The LEDs on both ends of the interface do not stay on all the time, only when data is being transferred.
