Set DeviceNet baud rate on the MA
The DeviceNet baud rate is defined for the entire network in the planning tool/control. The
baud rate is set on the MA 255
i
via the baud rate selector switch. Only if the baud rates are
the same is communication with the MA 255
i
possible.
Set the baud rate of the gateway via the
S3
rotary switch to the value defined in the control.

Finally, close the housing of the MA 255
i
.
Attention!
Only then may the supply voltage be applied.
Upon startup of the MA 255
i
, the device selection switch and the address settings are
queried and the gateway automatically sets itself to the Leuze device.

Check the applied voltage. It must be in the range b18V … 30 V DC.
Connecting functional earth FE
Ensure that the functional earth (FE) is connected correctly.
Unimpaired operation is only guaranteed when the functional earth is connected properly.
All electrical disturbances (EMC couplings) are discharged via the functional earth connec-
tion.
On delivery, the SWIO 1/2 are connected in parallel on PWR IN/OUT. This connection can
be separated with a jumper.
