Warnings
1. This device is for research use only!
2. The main device / the actual ETT Olfactometer is not MRI compatible.
3. Only the ETT Odorant carrier, tubing, respiratory belt and the applicator/nose piece are MRI
compatible and thus allowed into the magnet room.
4. Feed all tubing through an appropriately sized wave guide to avoid damage to it.
Software Installation (ETTDirectControl)
Access to our installer
For registered users, we are offering all our software as a download on our website
(emergingtechtrans.com). Access will be provided during the purchase of the device via email contact
with our support. Additional accounts can be created at any time upon request to
[e-mail].
With access to our support section (Figure 1) there are two to three different versions of
ETTDirectControl accessible. Depending on your request, we can unlock specific preview version access.
All installer packages describe supported operating systems and contain all necessary dependencies in
the package. Should it be required, we are also providing links to the driver and library packages below
separately.
It should be noted that the previous stable version, while still actively maintained is limited in its
features to support our users that are still using Windows XP. To use all new features, download the
current stable / release version. Please look at the Meaning of Update Rings on page 13, to find out
more about each version.
