If the Instrument_Manager application is unable to communicate with the NSRTW_mk2 it may be because the USB driver failed to install properly. To check the USB driver installation follow the procedure below:
1. Disconnect the USB cable.
2. If necessary take the PC out of stand-by.
3. Reconnect the instrument to an available USB port on the PC.
4. Make sure the charge LED lights-up green (charged) or yellow (charging). If not, make sure that the PC’s USB port is functional and that the USB cable is not damaged. If necessary try on a different PC, and/or with a different USB cable. The charge LED is just an indication that the port is powered. It should light-up, even if the USB driver is not installed properly.
5. Make sure that the operation LED starts blinking. If not go to step 6.
6. Open the Device Manager on the PC. This is usually found in Control Panel – System and Maintenance.
7. Just after connecting the instrument to the PC, observe that the Device Manager window refreshes.
8. Verify that an item named DDCI Platform or NSRTW_mk2 has been created in the list of devices.
9. If an unknown item appears, or an item named DDCI Platform or NSRTW_mk2 is found but has an exclamation mark (indicating a problem) beside it, disconnect the device and try re-installing the driver (see step 10).
10. To re-install the driver disconnect the instrument from the PC. Then Go into Start\All Programs\Noise_Sentry_RT_Management\Driver, and run DDCI_Driver_Install.exe. This re-installs the USB driver.
