Figure 1-12 USB Hard Key
The USB versions of the Hardkey key are inserted in a USB port after installing WebAccess SCADA Node software.
If a user fails to heed the above warning then you should have the user unplug the USB key and then remove the Sentinel USB key using Add/Remove Hardware applet in the Control Panel (Start ->Settings-> Control Panel -> Add/Remove Hardware). The User should then Install (or re-install) WebAccess SCADA Node software. This should repair the system and make the USB key operational.
All USB Sentinel SuperPro hard keys must be removed before installing software.
If Plug and Play is enabled (and after WebAccess is installed), when you install the USB key, a dialog box will appear saying, "new hardware found". It will find the driver if you have installed WebAccess. If you move the USB key to another port, it will re-install the driver (and you will get the pop-up dialog box again) if you have Plug-n-Play enabled
In general, the shipping and handling procedures suggested for the Sentinel Pro conform to the industry standards for handling electronic printed circuit boards. Your company may already have appropriate work areas and procedures in place.
Do NOT re-install the Hardkey driver if you are replacing the Hardkey or changing from Parallel to USB, if you have Plug-n-Play enabled (in Windows 2000 and XP, this is the default).
If WebAccess starts and complains that the Hardkey not found, and the key is plugged in, try testing the LPT port or USB port by printing over them to a printer.
Next, verify that your license control file matches your Hardkey. You may have pot configure a project with less than 150 tags (i.e. a project with just a SCADA node) in order to see both Hardkey and License file serial numbers.
If you have rebooted your PC, and can print over the port (LPT1 or USB), then try re-installing if WebAccess complains it cannot find key or there is a Hardkey mismatch.
The Rainbow Hardkey drivers are found at
You can reinstall the driver from the setup.exe in the Rainbow folder.
Remember to remove the USB Hardkey.
If you installed the USB key before installing WebAccess, you should unplug the USB key and then remove the Sentinel USB key using Add/Remove Hardware applet in the Control Panel (Start ->Settings-> Control Panel -> Add/Remove Hardware). The User should then Install (or re-install) WebAccess SCADA Node software. This should repair the system and make the USB key operational.
