4.4 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.

4.5 Inputs and Outputs

The device features two analogue/digital inputs and four digital outputs (PWM capable).

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.

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.
