4.2.1.2
CAN Bus
The CAN bus is connected to the device with two 5-pin M12 connectors male/female.
They are named CAN1 and CAN2 and are allocated as follows:
ATTENTION!
Under no circumstance c24V with pin 4 or 5!
NOTE!
The connectors of the inputs CAN1/CAN2 are connected in par-
allel, i.e. there is no input 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 from different manufacturers and are available for
most plugs and jacks. The CAN connectors can also be used as power supply.
4.2.2
Turn-on characteristics
Upon applying the operating voltage, the antenna requires 10 seconds startup time.
During this period, it is possible to start a firmware update (also refer to section 4.2.4
Following this period, the actual program starts. If configured accordingly (also refer
to Figure 16 on page 39), the transmission coils will be automatically tuned. This pro-
cedure takes another 16 seconds.
4.2.3
Interfaces
4.2.3.1
Serial (RS 232)
The serial output may be configured in various ways. The transmission rate is adjust-
able at 19200 or 38400 Bd, the output protocol may be chosen as either „Montir only“,
„transparent“ or „3964R“, the content of the output telegrams is configurable for the
last two. From a parameter list the required parameters may be selected.
