The setting will be active after a restart of the device.
When selecting “AUTO”, the type is determined by the physical voltage level at the digital interface. The automatic determination of
the type (RS232 or CAN) is done when the device is turned on.
CANopen and CAN J1939 are operated with the same physical voltage levels. If “CAN” is detected, the CANopen protocol is
activated (factory setting). If J1939 shall be used, “AUTO J1939” hast to be activated. For further information see chapter 16.3
"Configuration".
11.8 Baud rate CAN
The baud rate describes the transmission speed for the CANopen and the CAN J1939 protocol. The physical unit is kilobits per
second.
The following settings are available:
› 125 BAUD
› 250K BAUD
› 500K BAUD
› 1000K BAUD
› TERM. CAN
With the activation of „TERM. CAN“, the transmission line in the device will be completed with a terminating resistor of 120 Ohm.
11.8.1 Node ID CAN
The Node ID is the address, with which the device can be addressed via the CAN bus. The Node ID is required for CANopen and
CAN J1939 protocol.
Setting range: 1 … 127 (decimal)
Factory setting: 10 (decimal)
11.8.2 Baud rate RS232
The baud rate describes the transmission speed for the RS232 protocol. The physical unit is byte per second.
The following settings are available:
› 9600 BAUD
› 19200 BAUD
› 57600 BAUD (Transmission speed for firmware updates)
› 115200 BAUD
If the device is connected via RS232 interface, the parent instance must always be operated with the same baud rate.
11.8.3 Automatic transmission
With the activation of the automatic transmission, the measurement results are transmitted via RS232 interface immedi-
ately after a measurement. The transmitted data string corresponds to the response to the command “RVal”. For further
information see chapter 16.2 "Read commands".
Example for a data string:
