You can request a new activation code for your software here: Tinytag Explorer Activation Code.

If you require a copy of the software on a CD, please contact your local supplier.

By default, the current Tinytag Explorer 4.7 software is set to detect data loggers automatically.

If you are using an earlier version of the software you can upgrade free of charge here: Tinytag Explorer Upgrade.

To check the automatic com port detection is turned on, go to Options and Communication Options and make sure the Use fully automatic com port detection option has been selected.

If you are using Tinytag Explorer 4.6 or below, go to Options and Communication Options and select the correct port from the list displayed (if more than one is listed, try each in turn.  Usually, USB cables and pads will instal as the highest com port on the list). 

If the above doesn't resolve the problem, your USB cable may not have installed correctly.  To check whether this is the case, and to manually install the cable please see Manually Installing Drivers for USB Cables and Pads sections below.

It is recommended that USB pads and cables are used with Tinytag Explorer 4.7 or above (from this version of the software USB devices are automatically installed and detected).

You can upgrade free of charge to the latest version of Tinytag Explorer here: Tinytag Explorer Upgrade.

If you cannot connect to your data logger after installing 4.7, the USB drivers for your device may not have installed correctly.

To check whether the USB drivers for your device have installed correctly you should do the following:

- Plug in your USB cable or pad

- Go to your Device Manager

Windows XP Users: Start Button >> Control Panel >> System >> Hardware >> Device Manager

Windows Vista & Windows 7 Users: Start Button >> Control Panel >> Hardware and Sound >> Device Manager

- If the cable has installed correctly, it should be listed under Ports (COM and LPT) as a USB Serial Port with a COM number in brackets after it.  If this is the case and Tinytag Explorer is set to automatically detect loggers and still cannot connect, please contact your supplier or Tinytag Technical Support for further assistance.

- If the cable has not installed correctly it may be listed as a Gemini USB serial cable with a yellow exclamation mark next to it under Unknown or Other Devices.

- If this is the case, right click on the entry and select Update Driver (this will start a Hardware wizard running).

Windows XP Users:

- The first page of the wizard will ask you if Windows can search the internet or Windows Update for drivers, select the No, not this time option and click Next.

- Select the Install from a specific location option and point the wizard at the folder:

C:\Program Files\Tinytag\Tinytag Explorer\Drivers

And Next.

- Once the cable drivers have installed, click Finish.

Windows Vista & Windows 7 Users:

- Select the Browse my computer for driver software option and click Next.

- Point the installer at the folder:

C:\Program Files\Tinytag\Tinytag Explorer\Drivers

And click Next (you may be prompted to confirm your agreement to the installation).

- Once the cable drivers have installed, click Finish.

- If the device is still listed with a yellow exclamation mark against it, repeat the above process once again to set the device up as a COM port (the installation is a two-step process, first installing the drivers for the cable, and then setting up the cable as a COM port).

When you have gone through the installation for a second time the device should move to Ports (COM and LPT) and list as a USB Serial Port with a COM number in brackets after it.

Your cable or pad should now be ready to use, if you still cannot communicate with your data logger please contact your supplier or Tinytag Technical Support for further assistance.
