Mounting – Chapter 4
These panel jacks provide connection to the antennas. It is irrelevant whether one or
two antennas are connected. When using only one antenna, ANT1 or ANT2 can be
chosen. The displaying of CD1/CD2 on the front panel (see „Position of the LEDs“ on
page 19.) refers to the corresponding antenna input. The input voltage of ANT1 and
ANT2 are processed internally as US1/UD1 or US2/UD2.
4.2.2 CAN Bus (HG G-73350)
The CAN bus is connected to the device via two 5-pin A-coded M12 connectors
male/female (see „Casing dimensions interpreter HG G-73350/HG G-73351“ on
page 14.). There they can be found as BUS1 and BUS2, which are allocated as fol
-
lows:
The connectors of the inputs BUS1/BUS2 are connected in parallel, i.e. there is no
input or output. If the interpreter is installed at the end of the bus line, a CAN termi
-
nator has to be installed. Those terminators can be ordered form different manufac
-
turers and are available for most plugs and jacks. The CAN connectors can also be
used as power supply.
4.2.3 Profibus (HG G-73351)
Two 5-pin B-coded M12 male/female, indicated as BUS1 and BUS2 in Figure 1
above. There they can be found as BUS1 and BUS2, which are allocated as follows:
NOTICE
Damage to the device
If the voltage on the bus lines is too high, the bus driver in the interpreter and
possibly even other devices connected to the bus can be damaged.
Pin 4 or 5 must not be connected to voltages > 24 V!
