TECHNICAL KNOW-HOW

7.1

Termination resistors

Termination resistors are located on each side of the trunk line. The impedance is approximately 60 Ω

between CAN-HIGH and CAN-LOW.

Exception: In a large network with long stub lines, the longest distance between two devices should be es-

timated. It is also recommended to choose the longest distance in a network that consists of more than one

passive junction box.

Connection for diagnostics

We recommend providing a free connection for diagnostics. A port of the junction box or an extra Y-con-

nector in the network can be used. This access is important for fast diagnostics with büS stick and the

Bürkert Communicator software.

Furthermore, it can be used for measurements with external tools, e.g. GEMAC CANBUS Tester 2. In this

case, a measurement connection at both ends is recommended.
