CAN bus
The CAN bus is connected to the device with two 5-pin M12 connecters male/female
(see „Casing antenna HG 73350“ on page 6.). There they can be found as BUS1 and
BUS2, which are allocated as follows:
The connectors of the inputs BUS1/BUS2 are connected in parallel, i.e. there is no in-
put or output. If the interpreter is installed at the end of the bus line, a CAN terminator
has to be installed. Those terminators can be ordered form different manufacturers
and are availbale for most plugs and jacks. The CAN connecters can also be used as
power supply.
ATTENTION!
Do not c24V to pin 4 or 5!
3.2.3
Power supply and serial interface
Here a 5-pin M12 panel plug is used, in the figure „Casing antenna HG 73350“ on
page 6 this plug called PWR RS232 has the following pin allocation.
This connection serves the power supply. Additionally the serial interface RS 232 can
be used for parametrization.
