CAN Bus Termination
There are no internal termination resistors on either CAN channel inside the device. Therefore,
a proper termination of the CAN bus is needed, and the user has to make sure the CAN bus is properly
terminated at both ends.

Table 5 Inputs and Outputs
A load connected to a digital output pins DO1-DO3 may draw significant current. In case digital outputs
are used in a user application, it is strongly suggested to power the device from
an external power
supply
and not over USB. Otherwise, USB power limits might be exceeded.
4.6
USB
Micro-USB connector uses the standard pinout, and can be used for firmware upload or in
application as a virtual COM port.
4.7
Galvanic Isolation
The device does
not
have any galvanic isolation. The user has to make sure there are no ground loop
in his setup.
