2. Connect the data logger or data collector to your PC with a USB cable. If the PC does not recognize the recently connected device, an [Unknown device] message will appear.

* If that message does not appear, please check to make sure there are batteries in the connected device or that the device's power is ON. If the message still does not appear, it is possible that something is wrong with the USB terminal on the PC or on the device, or a broken wire in the USB cable.
* If the driver has been installed properly [USB Recorder Com] will appear in the device manager as shown in Step 7 below. (For TR-7Ui/7wf/7nw)
3. Right click on [Unknown device] and select [Update Driver Software(P)].

5. Specify the location of the device driver. Next depending on the circumstances select one of the following:

Click the [Browse] button and find the CD-ROM drive; then select the folder entitled [Device Driver].

For example, if the CD ROM drive is "D:" then it should be "D: Device Driver". If you are using RTR-57U, then select the folder [RTR-57U] and if you are using TR-50U then select the folder [TR-50U].
B: Installing from the folder where the software was installed
Click the [Browse] button and select the driver folder for the device from the folder into which the software was installed (if RTR-50 then select [Driver RTR-50]).
