10 Other sensor functions
10.1 Device address (0x2000) and baud rate (0x2001)
In the case of a change the device address and baud rate do not become effective
until after a reset (reset application, reset communication or hardware reset).
The inclination sensor from ifm is delivered with the device address (ECU) 25 and a baud rate of 250
Kbits/s.
10.2 Address claiming
The JN2301 sensor with SAE J1939 protocol supports the "dynamic address
claiming". At the factory, the device address of the sensor is preset to 25.
With this address, the sensor logs in to the network during start-up. If there is
no address conflict, i.e. no other network participant has the same address, the
sensor automatically starts the communication.
Arbitrary address capable (CA)
If the device address of the sensor is already used in the network, the participant
with a higher priority will be accepted by the network. The rejected lower prioritised
network participant will be assigned another valid address.
The rejected lower prioritised network participant will be assigned another valid
address. In this case the device address will change from 25 to 128 (or higher).
Valid values for the device address can be assigned from 0 to 253. (Device address 254

0; 255

10.3 Limit frequency digital filter (0x2043)
With the sensor it is possible to make continuously arising angle values insensitive
to external interfering vibrations.
Using a configurable filter (digital FIR filter) interfering vibrations can be
suppressed. The limit frequency of the filter is set via the FIR filter step (index
2043h).
