Structure and mode of operation
AD105D A05569_01_X00_00 HBM: public 7
3 Structure and mode of operation
The AD105D digital transducer electronics are part of the range of electronics
developed by HBM for static and dynamic weighing processes. They record
the measurement signals of connected sensors with strain gages. The trans
ducer electronics digitally condition the signals and deliver a fully-filtered,
scaled and digitized output signal for direct connection to bus systems or PCs
via the RS‐485 interface or CANopen. The transducer electronics can simply
and quickly be adjusted to the relevant system via various parameters.
The AD105D forms a unit with the transducer and cannot be replaced sepa
rately without recalibrating the system (SZA/SFA command). Loads cells or
force transducers, that are temperature compensated and for which the zero
value is set, can be used as transducers.
The PanelX software is available as a free download from the HBM website for
setting all the parameters in full, for realizing dynamic measurement signals,
and for frequency analysis of the dynamic system: www.hbm.com → Services
& Support → Downloads → Firmware & Software → PanelX.

Digitization is followed by filtering, using digital filters adjusted by the software
(FMD, ASF). The ICR command changes the output rate (measured values
per second).
In the working standard calibration of the transducer electronics (as-delivered
condition), 0mV/V corresponds to zero and the maximum capacity is either
1,000,000digits (NOV≠0), or 5,120,000digits (NOV=0). The two parameters
LDW and LWT enable you to adapt the characteristic curve to your require
ments (scale curve) and you can use the NOV command to standardize the
measured values to the required scaling value (e.g. 3000d). Detailed informa
tion can be found in the command documentation in the Online Help for the
PanelX program.
You also have the opportunity to
Sswitch from gross to net signals,
Sactivate an automatic zero on start up function,
Sactivate an automatic zero tracking function,
Slinearize the input signal with a third order polynomial,
Sactivate various digital filters. Filters with cut-off frequencies below 1Hz,
fast-settling filters for dynamic measurements, notch filters, and mean value
filters are available.

Read out the current measured value via MSV?. The format of the measured
value (ASCII or binary) is set with the COF command. You can also use the
COF command to activate the automatic measurement output. The measured
values are transmitted in the following format, depending on the COF com
mand:
Output format Input signal Output when NOV=0 Output when
NOV>0
Binary, 2 chars. (INT) 0 …maximum

0 …1,000,000 digits 0 …NOV
3.3 Adaptive interference suppression
Regardless of the mode of operation, you can use the ADF command to acti
vate automatic interference suppression with adaptive filters. Interference fre
quencies are automatically found during the measurement and suppressed by
comb filters and averaging. The maximum filter settling time can be limited with
the TMA command.
3.4 Digital output
Use the digital output as a limit switch, for example. The gross or net value is
monitored depending on the parameters for the LIV command.
Gross or net value≥switching threshold: low output voltage (≤1V)
Gross or net value<switching threshold: high output voltage (≥6V)
You can also use the POR command if you deactivate the limit value function
(LIV1,0;):
POR0; Low output voltage (≤1V)
POR1; High output voltage (≥6V)
POR,0; LED OFF
POR,1; LED ON

Structure and mode of operation
AD105D A05569_01_X00_00 HBM: public 11
The voltages relate to the GND potential. The maximum power loss of the
switching transistor is 250mW. In the default settings, the LED function is ac
tive and indicates whether the power supply is present.

Mechanical installation
12 A05569_01_X00_00 HBM: public AD105D
4 Mechanical installation
You can install the AD105D in a transducer by mounting the motherboard on
the side of a transducer, for example. Ask HBK for a suitable shielding plate, if
necessary.
You must use a shielded housing and shielded cable if you do not mount the
AD105D within a closed (electrically conductive) transducer housing.
Notice
The AD105D is not protected against electrostatic discharges (ESD). Static
discharges can destroy the electronics.
Therefore ensure you have discharged any static charges before touching the
motherboard parts or connections.
Important
Before installing several transducer electronics modules in a plant with a bus
system, please note the following:
Before establishing a connection to the bus system, connect the transducer
electronics individually to a PC to set different addresses.

Important
The AD105D is an unshielded motherboard and is thus not EMC-tested. Either
install the electronics in a closed (electrically conductive) transducer housing or
in a separate EMC-tested housing.
Connect the transducer, AD105D housing, and cable shields to a joint ground
to realize effective shielding against electromagnetic interferences. The elec
tronics is protected against interferences with filters on the interfaces and exci
tation voltage.
5.1 Transducer connection
A 4-wire shielded cable is sufficient for connecting the transducer. If the trans
ducer has a 6-wire cable, the bridge excitation voltage and sense lead must be
connected as illustrated in Fig. 5.1. The connection should be as short as pos
sible. Depending on the bridge resistance of the transducer being used and the
length and cross-section of the transducer cable, there may be voltage drops
that can reduce the bridge excitation voltage. The voltage drop on the connec
tion cable is also dependent on the temperature (copper changes its resistance
with the temperature). The output signal of the transducer changes proportion
ally with the changing bridge excitation voltage. The 4-wire circuit used here
will result in measurement errors if temperatures fluctuate. This is caused by
the temperature-dependent cable resistance.
When establishing a measurement chain where the electronics are positioned
outside the transducer, ensure that the AD105D uses a rectangular carrier fre
quency for the bridge excitation. The cable length between AD105D and the
transducer should therefore be limited to max. 100cm. A max. length of 30cm
should not be exceeded for precision applications (≥3000d).

5.2 Bus connection
Important
Before installing several transducer electronics modules in a plant with a bus
system, please note the following:
Before establishing a connection to the bus system, connect the transducer
electronics individually to a PC to set different addresses.
The transducer electronics are supplied with an RS‐485 or CAN bus interface
(CANopen standard CiA DS301). The interface of the transducer electronics
relates to the GND, while the interfaces of the bus nodes must also relate to
the GND.
Use a shielded cable as the interface cable. The shield should always be con
nected to the ground potential at both ends.
Details of the procedure for setting up the transducer electronics and an expla
nation of the various settings, including for the interfaces, as well as the rele
vant commands, can be found in the online help of HBM's PanelX program,
which you can download free of charge from the HBM website: www.hbm.com
→ Services & Support → Downloads → Firmware & Software → PanelX.
For the interfaces, read the sections relating to your interface in the chapter
headed "Communication via one of the interfaces".

6 Interfaces
6.1 RS-485 2-wire interface
You can either connect a single transducer electronics module via the RS-485
interface or, by configuring a bus system, connect up to 32 transducer elec
tronics modules to one RS-485 interface. In this, all the electronics modules
are connected in parallel on one line. The total length of the line may be up to
500 m. The software uses the different addresses to differentiate between the
transducer electronics modules. If the control computer only has an RS-232 or
USB interface, an interface converter is required.

Fig. 6.1 Connection of several electronics to a PC via RS‐485
The interface signals T/RA and T/RB are switched in parallel for all AD105Ds
and the control computer. The transducer electronics already include the nec
essary bus termination resistors (termination resistor) that can be activated
with the STR software command. So no additional bus termination resistors
are needed on the electronics end. The ground reference for all of the interface
signals is based on the supply voltage ground (GND).
Address range
An address is necessary to be able to identify the nodes in the bus system un
ambiguously. The address may be between 0 and 89. The factory setting for
the address is 31. Set a different address with the ADR command.

Interfaces
AD105D A05569_01_X00_00 HBM: public 17
Baud rate
You can set baud rates from 9600 to 115,200baud with the BDR command.
The factory setting is 9600 baud.
Saving settings
To complete the settings, save all of the parameters to the non-volatile mem
ory of the transducer electronics with the TDD1 command.
6.2 CANopen interface
The CANopen interface operates according to the CiA DS301 standard (CAN
in Automation) - see also ISO 11898. Communication runs via two lines with
CAN HIGH and CAN LOW.
The level of all lines is relative to GND. The GND (0V) of the supply voltage
must therefore also be connected, but you must not connect GND to the
shield. Use a separate line to connect the digital ground of the nodes with the
GND (0V) of the power supply.
Important
You must connect bus termination resistors (each 120W) at the start and end
of the bus. The transducer electronics modules do not contain a bus termina
tion resistor for CANopen. You can only connect the resistors at the ends of
the bus system. If you are using more than two terminating resistors, or they
are not located at the ends, communication will be limited (bus errors) or will
not work at all.

The maximum cable length is the total line length, calculated from the length of
all the stub lines for each bus node and the line length between the nodes. The
length of the stub lines per node is limited and depends on the bit rate being
used.
Bit rate
The bit rate factory setting is 125kBit/s. To change the bit rate use the PanelX
program or a configuration tool for CANopen. The transducer electronics sup
port the LSS protocol as defined by CiA DS305. So you can change the bit rate
and address with the PanelX program or a CANopen configuration tool. Gener
ally the change can only be made for one node. If necessary disconnect the
node from the bus system or deactivate the other nodes.
