Baud rate
You can set baud rates from 9600 to 115,200 baud with the
BDR
command.
The factory setting is 9600 baud.
Saving settings
To complete the settings, save all of the parameters to the non-volatile mem
ory of the transducer electronics with the
TDD1
command.

CANopen interface
The CANopen interface operates according to the CiA DS301 standard (CAN
in Automation) - see also ISO 11898. Communication runs via two lines with
CAN HIGH and CAN LOW.
The level of all lines is relative to GND. The GND (0V) of the supply voltage
must therefore also be connected, but you must not connect GND to the
shield. Use a separate line to connect the digital ground of the nodes with the
GND (0 V) of the power supply.
Important
You must connect bus termination resistors (each 120
W
) at the start and end
of the bus. The transducer electronics modules
do not
contain a bus termina
tion resistor for CANopen. You can only connect the resistors at the ends of
the bus system. If you are using more than two terminating resistors, or they
are not located at the ends, communication will be limited (bus errors) or will
not work at all.
