In this section you can read more about the CAN channels, power supply and LED
indicators.
3.1
Hardware installation
For the Kvaser Memorator Light HS v2 to communicate with the host computer, a
compatible version of the Kvaser driver and firmware must be installed.
After the driver has been installed on the host computer, the firmware may then be
downloaded and installed on the Kvaser Memorator Light HS v2.
The latest version of the driver and firmware can be downloaded from
www.kvaser.com/download.
The driver is installed by running the file
kvaser_drivers_setup.exe
.
The Kvaser Memorator Light HS v2 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 information on how to upgrade the firmware, see Section 4.5, Updating the
firmware, on Page 14.
3.2
USB connector
The Kvaser Memorator Light HS v2 has a standard USB type “B” female connector.
Connect the device to your computer using any high quality USB 2.0 certified
cable. The maximum USB cable length is 5 m (
∼
16 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 an effective cable length of up to 25 m (
∼
82 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 tends to be more reliable than
only foil. Furthermore, longer cables may introduce signal
degradation and timing issues that, if necessary, can be mitigated
using shorter cable segments combined with hubs that amplify
the signal and handle delays on a per-cable basis.
3.3
CAN channels
The Kvaser Memorator Light HS v2 has one CAN Hi-Speed channel with a 9-pin
D-SUB CAN connector (see Figure 2 on Page 8). See Section 4.2, CAN
connectors, on Page 12 for pinout information.
