2Initial Operation of the Measuring Device
For the installation and operation of the measuring system, the applicable national regulations for the in-
stallation and operation of electrical systems, as well as the general rules of technology and these operat-
ing instructions are decisive.
Galvanic isolation between power supply and analog output
ground analog output = ground housing
2.1 Pin assignment supply voltage
Pin1: ground
Pin2: V- (0 V)
Pin3: V+ (24 V)
2.2 Pin assignment analog output
Pin1: 0-10 V analog output
Pin2: analog output GND (for 0-10V resp. 4-20mA)
Pin3: 4-20 mA analog output
Pin4: not connected
Pin5: not connected
2.3 Device parameterization
The device can be parameterized via the user interface (see chapter 3) or the TCP interface (see
chapter 4).

______________________________________________________________________________________
U447_ExactSonicP_B_e_220628

3User Interface
The user interface consists of an illuminated 7" touch display, which is embedded in the housing.
After starting, the tab graph is displayed. At the top, you can switch to the respective tab by tapping on
the corresponding tab.
3.1 Tab Graph
Task: of the instantaneous values (textual and graphical) and the quantity counter. Locking and unlocking
option of the user interface.
In the Tab Graph, the measured values in the available graphs are displayed averaged over a period of
100 ms. 200 measured values of 100 ms each are shown, which corresponds to an observation period of
20 seconds.
The graph offers different views, which can be switched through in the following order by tapping on the
diagram itself.
common graph for flow, temperature, pressure, humidity1with separate Y-axes
graph for flow
graph for temperature
graph for absolute pressure
graph for humidity1
three separate graphs for flow, temperature, pressure and humidity1
Die unit of the flow value can be set in the Tab Settings (see chapter 3.3).
By tapping on the symbol or on the upper right edge, the interface can be locked or unlocked. To
unlock the security code, which is „71334“ by default, is required. It is recommended to change the
security code directly after initial operating (see AK command „ESCO“ in chapter 4.4.5) to protect the unit
against unauthorised access. The interface is automatically locked again after the set "Display switch-off
and TCP lock time" (see chapter 3.3 or AK command „EDTT“ in chapter 4.4.5) has expired.

______________________________________________________________________________________
U447_ExactSonicP_B_e_220628
8/18
3.2 Tab Control
Task: Starting and stopping the measuring function, resetting the quantity counter, restarting and
shutting down the unit.
In Tab Control the measurement can be paused. The graph is no longer updated when the measurement
function is stopped; the last measured value is permanently displayed. The measurement data via TCP
interface also no longer change, the last measured values are always transmitted. The analog output is
also frozen at the last value.
The quantity counter (forward, as well as backward) can be reset to 0 by tapping the "Reset" button.
To restart or shut down the unit properly, use the buttons in the lower section. It is always advisable to
shut down the unit properly to avoid loss of data (settings, quantity counter, ...).

4TCP Interface
4.1 Communication between evaluation unit and ExactSonic P
The communication between the evaluation unit and the ExactSonic P takes place via TCP via the built-in
RJ45 socket. In this communication, the master is the evaluation unit, the ExactSonic P is the slave. The
master sends a command, whereupon the slave responds accordingly. The protocol, which is referred to
here as the AK protocol, was implemented according to the VDA standards of the "Standardisation of Ex-
haust Gas Measurement Technology".
4.2 Interface Specification
The interface is an RJ45 socket (8P8C) according to the ISO/IEC 11801 standard. Any standard network
cable can be used, which is also commonly used with PCs..
4.3 Security
Access to the device via TCP is provided with a security code. This is set to "71334" at the factory. This
should be changed directly during initial operation in order to protect the device from unauthorized access
(see AK command „ESCO“ in chapter 4.4.5).
The query commands (Axxx) can be used at any time without entering the security code. To query or
change the settings or to control the device, it must first be unlocked with the "STLK" command and the
security code. The device is blocked again after the blocking time for display and TCP (see command EDTT
in chapter 4.4.5), as well as after a restart.
4.4 Protocol Description
Each telegram begins with an STX (Start of Text) as the first byte. The second byte can be any ASCII
character, the blank character is preferred for reasons of readability. This is followed by four bytes of the
AK command. This is followed by a blank as the 7th byte, a capital "C" as the channel identifier, the chan-
nel number (see respective AK command), another blank and then the data bytes.
If no data bytes are sent to the device, the command is interpreted as a read command. If the command
contains one or more data bytes, it is considered a write command. Each command is concluded with an
ETX (End of Text).).
The AK commands are divided into three categories.
query commands (Axxx)
setting commands (Exxx)
control commands (Sxxx)
The response telegram no longer contains the channel identifier "C" and the channel number. The error
status is contained in its place, which signals no error with "0" and an error with unequal "0”. Measured
values for which the error status signals an error should not be used for evaluation, but discardedIf the
error status permanently shows an error, the device must be restarted or checked..
