Multi-point connection using daisy chain
Daisy chain connection is a multi-point network topology based on connecting multiple terminals in a ring. The
wiring consists on connecting the TX terminals of each device to the RX terminals of the next device. An example of
daisy chain wiring of multiple Nix is shown in the next figure.
Termination resistor
The use of
termination resistors at the RX side
of each differential pair (120 Ω between RX+ and RX- of
both host and slave) is essential for correct operation of the RS485 communication.
For long cable
distances (> 10 m) a termination in the TX side
is also recommended.
Nix Servo Drive version 1.1.0 includes a termination on the RX terminals. Therefore, a 120 Ω termination
resistor should be placed at the end of Nix TX line (RX of the host). Nix Servo Drive version 1.2.0 includes a
termination on the TX terminals too.
Suggested termination resistor: Xicon
