Note. Terminating resistors must be installed as close to external device/Product connectors as possible.

External device may include a terminating resistor. In such cases it is not required to install a terminating resistor from the external device side. Presence of a terminating resistor in the external device is determined on the basis of the external device documentation.

The GND power supply circuit (white wire) of BIS 20240 should be connected to the vehicle's body or to the battery, using the BR15 galvanic isolation unit.

Note. The number of products connected to one external device in this diagram is from 2 to 31.
