3.2.3. System installation instruction

Operator Room

Connect the Fiber Transmitter to the desired PC or video output device HDMI port. To utilize the computer’s DVI or DisplayPort interface, use the DVI/DisplayPort-to-HDMI adapter that comes with the system.

Connect the EDID adapter straight to the fiber transmitter, this will give the right screen settings to the computer and also make the computer remember the NNL monitor when it’s turned off.

Connect the fiber cable to the Fiber Transmitter and feed the fiber cable through the waveguide into the MR suite.

Connect the micro USB to the Fiber Transmitter and to the computers USB port. If a DVD/BluRay-player is used as a source, connect the USB cable to the supplied USB power supply.

The Fiber Transmitter also acts as an USB hub, providing access to the monitor camera and the USB connectors at the rear of the monitor.

Magnet Room

Danger: The LPS contains ferrous material and extreme caution must be used while moving and installing the device in the MR suite. Improper handling of LPS within a magnetic field of greater than 20mT may result in serious injury or death. Only technicians with knowledge of the risk of introducing ferrous objects into the MR are allowed to perform the installation.



First decide where to place the LCD Monitor. It is normally located at the back of the scanner or at the side of the patient bed. Consider the length of the power cable from the LPS to the LCD.

Then decide where to place the LPS. Use a gauss meter to measure the magnetic field at this location or use the technical drawings for the magnet room to ensure that the LPS location is at below 20 mT (200 Gauss). Note that the LPS must be located near an AC power outlet.

Before taking the LPS into the magnet room, verify that the path which the LPS will be moved to the installation location, is outside the 20 mT (200 Gauss) limit.

Once the final location for installation has been selected and the path for moving the LPS

into the magnet room has been determined, only then should the installation take place. For safety reasons, only the installer should be present in the magnet room during the installation.

Secure the LPS in a fixed location where the magnetic field is less than 20 mT (200 Gauss). A Kensington Lock should be attached to the back of the LPS (4) to avoid unwanted movement by untrained personnel. The Kensington Lock should restrict movement of the LPS to always be outside a 20mT (200 Gauss) limit.

Connect the fiber cable to the fiber input on the LPS (7).

Connect the LCD power cable between the LCD Monitor and the LPS. Start by connecting the end that is to be connect to the LPS end (1).

Connect the fibers that are bundled into the power cable. On the LCD monitor, use the connector that is marked with “Fiber input”only.

Connect the power cable to the LPS (5) and to the mains outlet. Switch on the LPS (3) and confirm that the backlight of the LCD lights up and the NNL splash screen is present.

Thanks

Warning

IMPORTANT! The end with the ferrite bead is to be connected to the LPS first. It can be identified by the rectangular shape and a warning label relating to ferromagnetic material. This has to be done before connecting the cable to the LCD monitor.
