Kvaser Memorator Light Hardware
This section describes the CAN channel, power supply, LED indicators, and other
aspects of the hardware.
3.1
Hardware installation
The Kvaser Memorator Light may be inserted in any free USB socket on the host
computer. You do not need to switch the power off before inserting or removing the
device.
For the Kvaser Memorator Light to communicate with the host computer, the
correct version of the Kvaser driver and firmware must be installed. The firmware is
downloaded and installed directly on the Kvaser Memorator Light and the driver is
installed on the host computer. The latest version of the driver and firmware can be
downloaded from http://www.kvaser.com/download/.
The driver is installed by running the file
kvaser_drivers_setup.exe
.
See also Section 5.5, Updating the firmware, on Page 16 for more information.

3.2
USB connector
The Kvaser Memorator Light has a standard USB type “B” receptacle connector.
Connect it to your PC using any high quality, USB 2.0 certified cable. The
maximum USB cable length is 5 meters (approx. 16.5 ft.). If you need a longer
cable, you can use USB hubs or USB extension cables with a built-in hub. By
chaining up to 5 hubs, you can achieve a cable length of up to 25 meters (approx.
83 ft.)
As USB cables become longer they are more sensitive to EMI, because they make
a longer antenna that can pick up more noise. These issues can be mitigated by
using higher quality cables with better shielding. Thicker cables tend to be better
than thin ones, and braided shielding tend to be more reliable than only foil.
Furthermore, longer cables may introduce signal degradation and timing issues
