4.3.2 Connectors
The CAN connectors embedded in the lower half of the front panel are used for both CAN
signal communication and power supply. The interface cable connects the measurement
module to the data acquisition system (PC) and to the power supply. The multi connectors
in the upper half of the front panel are designed for connecting the sensor cables to the
measurement module. If required, the measurement modules can be connected to ground
by using the M6 threaded mounting hole in the top side of the housing.
4.3.2.1 CAN sockets
The CAN sockets are connected in parallel so that the signals are always present at both
sockets. Both sockets can be used for either CAN IN or CAN OUT. This enables simple cabling
with only one cable between two measurement modules. At the end of the measurement
chain, a CAN termination resistor is plugged into the open CAN socket.
NOTE!
i
Be particularly careful when connecting third-party devices to a measu-
rement bus with HV AD CAN TBM Series measurement modules.
 Make sure that the configuration settings are compatible for all
devices (same CAN bit rate, different CAN identifiers).
 Make sure that this work is only carried out by qualified and trained
personnel.
NOTE!
i
The CAN sockets for CAN signals and power supply are connected in
parallel and have identical pin assignments. The signal applied to a
specific pin is therefore always available at both sockets
 Make sure that this work is only carried out by qualified and trained
personnel.
CSM uses LEMO 0B sockets as standard for the CAN sockets. The following plug with plug
insert is required for connecting a cable to this socket:

4.3.2.2 8-pin multi connectors LEMO Redel
Two sensors with sensor excitation (HV AD4 IF20) or four sensors without sensor excitation
(HV AD8 OW20 und HV AD4 XW20) can be connected to an 8-pin multi connector.
LEMO 2P sockets are used as standard for the measurement inputs.
Two plugs with socket insert (female) are currently available for connecting a sensor cable
to an HV AD CAN TBM measurement module:
fCFC.H08.TLA.Cxxx (code C for HV AD4 IF20)
fCFB.H08.TLA.Cxxx (code B for HV AD8 OW20)
fCFD.H08.TLA.Cxxx (code D for HV AD4 XW20)
In addition, an orange-colored bend relief is available for these plugs:
fGMA.2B.xxx.DS (orange for HV AD4 IF20 and HV AD8 OW20)
fGMA.2B.xxx.DR (red for HV AD4 XW20)
