9.3.6 Selecting the communication
Here you can define the configuration of the digital interface.
Serial RS 232
Data output via the RS 232 interface.
CAN
Data output via CAN bus.
AutoDetect
The connected collector is automatically detected and the
data is output accordingly.
▶
Select the data transmission speed of the CAN interface.
The selected speed must comply with that of your CAN bus; otherwise, no com-
munication will be possible.
50 / 125 / ...
▶
Select the speed in kBaud.
Term. CAN
Connects a 120 Ω resistance to terminate the CAN strand.
This option should always be activated.
Here you can display the set node ID of the online particle monitor. You need it in
order to address CAN commands correctly and/or to assign CAN signals correctly.
▶
Select the data transmission speed of the RS 232 interface.
The selected speed must comply with that of your system; otherwise, no commu-
nication will be possible.
Here you can select the data which is to be transmitted via the digital interface.
You can transmit the current measured and voltage values as well as the time.
You can transmit one, two, or all three values.
For the "Communication/Autom.transm./Spec.voltage" setting, a BAUD rate
of 115200 BAUD is required.
9.3.7 Configuring the display
The display illumination will by default go out after ten seconds ("Dimming 10 s").
You can, however, also switch it on permanently ("Continuously").
9.3.8 Sensor parameters
In this menu item, you can display different parameters of the online particle monitor:
Here, the last measurement results of the size classes as well as the index of the
