1. Introduction

1. Introduction

Publicount is a contact-free people counting system based on radar technology to
determine customer traffic in a shopping centre or in certain areas of a shopping
centre.

To do this, sensors are installed above the relevant access points. These send
physical measurement data to a data-logger, also called sensor management centre
or SMCs, also installed in the entrance area.

The SMC evaluates the numbers of people entering and leaving and assigns the
people counts to the time of day. Customer traffic data are stored in the SMC for the
last 30 days.

A number of these SMCs are linked to a PC which stores customer traffic data on a
long-term basis and allows further processing in graphic or tabular form.

These operating instructions contain information on

- assembly of the counting equipment (positioning and cabling of the SMCs

and sensors)

- configuration of the counting equipment (operation of all firmware versions)

- firmware updates for the counting equipment (SMCs and sensors).

Warning: Failure to follow the guidelines for the assembly and cabling of

sensors/SMCs described in these operating instructions may
result in damage to the equipment!

2. Sensor installation

2. Assembly of sensors

This chapter describes how the sensors have to be projected (location of projection
fields, number of sensors to be installed) and how the sensors are connected to the
SMC (connector assignment).

The sensors are integrated into the ceiling or into cable channels or suspended
directly from the ceiling.

Warning: Sensor mountings must be insulated for correct operation. The

sensor should not have any contact with other electrical power
circuits, e.g. the earth circuit. Failure to comply with this
instruction may result in damage to the sensor.

2.2. Number of sensors to be installed

The number of sensors to be installed depends on the firmware version of SMC
used.

2.2.1. SMC Firmware 1.x

The number of sensors to be installed depends on the installation height and the
width of the section to be covered.

The distance between the sensors is installation height / 3. The distance between
the wall and the outside sensors is installation height / 6.

Operating Instructions HUZ3 8 / 8

2. Sensor installation

2.3. Position of the projection field

For correct operation, the sensors must be projected in such a way that

• there are no moving parts within the sensor field, such as:
o entrance doors which swing through the sensor field

exception: glass doors without metal gridding

o escalators, fans

• there are no people present in the sensor field for long periods, e.g.
o if there are goods located within the sensor field which the customer

walks around a number of times and so is counted more than once

o if queues form here.

• the construction on which the sensors are mounted is vibration-free.

In addition the following points must be taken into account with respect to the position
of the projection field:

• If the projection field lies too far inside the shop there is the likelihood that

people will remain within the projection field for a considerably longer time
(they come in and then think first of all about where they want to go / goods
displays in the vicinity of the entrance area / ...).

• If the projection field lies too far out it is possible for people to be counted who

have not entered the shop (looking in from outside and then going away again
/ walking outside along the line of the sensor field / ...)

• If the entire entrance area is not covered, then people can walk in such a way

that they do not cross the counting area (see Fig. 2.3-1)

• The projection field should not be directed at metal flooring elements (if the

store is in the construction phase, mats can be used which do not contain any
metals)

Getting the projection right is crucial for later adjustment. If the projection is poorly set
up, a counting accuracy of 95% can only be achieved with a very great deal of
adjustment, or possibly not at all.

If the client wishes the sensors to be positioned differently (e.g. for optical
reasons), it must be pointed out that this means that a counting accuracy of
95% can no longer be guaranteed.

A few examples of the position of the projection field are given on the next page.

Operating Instructions HUZ3 9 / 9

2. Sensor installation

The following illustration shows the entrance of a store (the dark rectangles represent
the wall where the entrance ends). For counting to be correct, the projection fields
must be arranged to that their centre line covers the entire entrance area.

Inside

Fig. 2.3-1 Position of projection fields at the entrance

All sensors in this entrance area are to be given the same entrance number in the
configuration assignment (e.g. all entrance 1).

In the following illustration, the entire entrance area is not covered, which means that
people can walk in such a way that they do not cross the counting area.

2. Sensor installation

2.5. Connector assignment

Each sensor is connected to the SMC via a 6-core, flexible shielded ............ cable.

A shielded 8-pin RJ45 connector is used on the SMC side and an unshielded 6-pin
RJ45 connector is used on the sensor side. The shielding is applied on one side of
the SMC.

Warning: If the shielding is applied to both sides, this may result in damage

to the sensor.

The RJ-45 sockets of the SMC also have contact lugs for shielded RJ-45 connectors,
so that, as an alternative, the shielding can also be applied to the connector housing
instead of pin 1 and pin 8.

The LEDs on the RJ-45 sockets of the SMC come on when a data transfer with a
sensor occurs on the corresponding port or this is attempted on the part of the SMC.

3. Connecting MSPs together

3. Connecting SMCs together

If a number of SMCs are required in order to cover all the entrances and/or access
ways in a store, these are to be connected via the RS485 data bus in a ring line open
on one side.

Cable ................ is used, as with the connection of the sensors.

The shielding is connected on one side of the cable with the shielding of the modular
connector.

Warning: Applying shielding to both sides may result in communication

errors and, with the HUZ2(b), also to damage to this.

Results are displayed and counting data are stored long-term on a PC. For this
purpose, PUBLICOUNT GmbH offers Publicount Soft and Publicount View software.

The RS485- Ports of the SMC are supposed for the data request. The RS232- Ports
are supposed for User Configuration of the SMC, maybe with use of a Bluetooth­Module. So the SMC initialises a Bluetooth Module after Power On. A Modem
connected to RS232 will loose its Configuration in case of this initialisation.

4.1. End equipment connected to the RS232 port of a single SMC

This option should only be considered for small units with just one SMC and a
maximum line length of 20 m between SMC and PC.

For this, the SMC must be also positioned next to the end equipment.

Option 1: PC and SMC are connected via a standard zero modem cable. The

data connection to the SMC is via the RS232 port. An additional 230 V
connection must be available for the PC.

Option 2: Ethernet server and SMC are connected with a standard zero modem

cable. The data connection to the SMC is via the RS232 port. An
additional 230 V connection and the Ethernet connection / modular
RJ45 must be available for the server. Both connections to the Ethernet
server are plug connections.

Option 3: Modem and SMC are connected over a RS485 Converter. The data

connection to the SMC is via the RS485 port. An additional 230 V
connection and an analogue telephone connection must be available for
the modem. Both connections to the modem are plug connections.

4.2. End equipment connected with the RS485 bus for more than one SMC

This option must be adopted when a number of SMCs are used.

For the sensors, cable .......... should be run from a free bus connection on the first

SMC to the end equipment in position.

The bus is connected to the RS485 converter in the usual way here.

The RS485 converter has a 9-pin SUB-D plug as its RS232 data connection. The
end equipment is connected to it as already described in the previous section.

The RS485 converter does not need its own 230V connection. Power is supplied to it
from the connected SMC and for this reason the bus line between SMC and
converter must be a 4-core line (connector arrangement the same as the connection
lines between SMC and sensors). Cable shielding is provided on both sides.

5. Operating the SMC

A terminal programme is required for operating the SMC.

The connection between PC and SMC can be produced via a zero modem cable to
its RS232 interface or, optionally via Bluetooth.

With Bluetooth, the stages described in Appendix A4 must be followed in order to
make a connection.

5.1. Terminal settings

The HyperTerminal supplied with Windows, for example, is suitable as the terminal
programme. This is found under

Start – Program Files – Accessories– Communication - HyperTerminal

The settings are:

Baud rate 9600
Data bits 8

Parity none
Stop bits 1
Flow control none

In addition, under

Start – Setting – System control - Keyboard

the delay must be set to short and the repeat rate to high.

5.2. General operation

The following commands function independently of the SMC firmware and SMC
being used. In contrast to the HUZ2, the two ports (RS232, PC) are separate in the
SMC, i.e. there are no outputs over RS485 during the configuration of the SMC via
RS232. Therefore data may be called up by the PC over RS485 parallel to
configuration.

5.2.1. Interrogation into SMCs connected

If key 'a' is depressed for 2-3 seconds, the connected SMC responds with the
message

HUZ3 Version 1.1 = PCHUZ91 English - Address 1

This gives the firmware version, language and address of the SMC. The address is
set to 1 at the factory.

In the example Firmware version 1.1 = PCHUZ91 (emulated version)

Language English

Address 1

If a number of SMCs are connected to the RS485 bus, this cannot be interrogated
with 'a'.

5.2.2. Activating the SMC

The SMC is activated as follows:

1. Hold key '0' down for 2 - 3 seconds

2. Enter the address of the SMC (e.g. 1 for address 1)

3. Confirm input with Enter

The response by the SMC contains additional operational options, e.g. start a control
count.

Operating Instructions HUZ3 19 / 19

5. Operating the MSP3 – Firmware 1.x

5.3. Firmware 1.x

Firmware version 1.x represents the replacement firmware for HUZ2 versions 60, 61,
90 and 91.

For operation the sensor versions RN-SE2, KF or KF32.x are required.

All points of the HUZ2 firmware are contained in this, under other names. In contrast
to the HUZ2 versions, the SMC differs in the following points:

- in-counts / - people / ... renamed as „Counts in“ / "Person in“ / ...

- out-counts / - people / ... renamed as "Counts Out“ / Person out“ / ...

- The "Demo Modus“ has been renamed "Control Counting“ and is selected

using key 'c’. As up to 12 inputs are possible, the entrances to be displayed
can be selected by key 'd' (Display Entrance).

- The "Test Modus“ has been renamed "Live Mode“ and is activated with key 'l'.

- "Basic settings" and "Assignment" have been brought together in a

configuration menu which is opened with key 'c' (Configuration Menu). This
menu also displays the firmware version of the sensors. The operation of this
menu is described below.

- The SMC has a Bootloader, by means of which it is possible to update the
SMC firmware.

- All parameter inputs (e.g. address) can be interrupted with ENTER or ESC.

The following remain the same:

- Connected SMCs are interrogated with key 'a':

- Activate the SMC by keeping key '0' depressed (approx. 2 seconds), then

enter the SMC address and confirm with ENTER.

- Auto-test is still selected using key 's'. All data stored are lost with the auto­test.

In the text below there is first a description of the setting parameters of SMC version

1.x, with their meanings. Then the operation of the SMC is described.

Operating Instructions HUZ3 20 / 20

5. Operating the MSP3 – Firmware 1.x

5.3.1. Sensor measurement data, counting parameters of the SMC

If a person crosses the sensor field, the following measurement data are produced:

1: a 0 i 0 o 0
2: a 32 i 5 o 0
3: a 63 i11 o 0
4: a 75 i19 o 0
5: a 96 i31 o 0
6: a116 i41 o 0
7: a115 i48 o 0
8: a125 i48 o 0
9: a 18 i 0 o 0
10: a 17 i 0 o 0
11: a 0 i 0 o 0
12: a 0 i 0 o 0

Each line represents a period of 140ms.

In the first column (a) is the amplitude measured (signal strength), in the second (i)
and third (o) the number of counts measured for In and Out directions.

Counts are path impulses and contain directional information. By crossing the sensor
field a person always produces approximately the same number of path impulses.

These impulses are evaluated and added as soon as they reach a certain signal
strength (amplitude > 10). Therefore this value is dependent on the Gain amplitude
set.

If the counts measured exceed the threshold value set for Counts In, Counts Out,
then a person is counted.

In the example a person crosses the sensor field in the In direction.

The setting parameters should be such that 50..50 counts are measured for a
person of average size. If fewer counts are measured, the amplitude should be
increased. If more counts are measured, the amplitude should be decreased.

Operating Instructions HUZ3 21 / 21

5. Operating the MSP3 – Firmware 1.x

Group Delay parameters give the measurement period after the count threshold has
been exceeded. As counting behaviour, especially with a number of people (groups),
is affected by this, this parameter is referred to as Group Delay.

e.g.: Counts In = 40 , Group Delay = 2

In the example above, the threshold in line 6 (a116 i41 o0) is exceeded. The
measurement of this person is now ended after 2 lines (Group Delay –setting).

The next measurement of a person can then start.

With a low Group Delay value, more people are counted overall. However, the
counting accuracy for individual people deteriorates.

With a high Group Delay value, fewer people are counted overall, but the counting
accuracy for individual people is better.

Collection of counting parameters

The following parameters are set separately for each sensor:

Gain sensor amplification setting

Counts In threshold value for counting one person In

Counts Out threshold value for counting one person Out

The following parameters are set once for all sensors:

Group Delay Sensor group delay under one sensor

Group Delay Mid group delay between two sensors

5. Operating the MSP3 – Firmware 1.x

The following setting parameters exist for the sensors:

Entrance The entrance to which the sensor is assigned. The SMC can

handle up to 12 entrances here.

Sensors monitoring the same entrance must also be given the
same entrance number.

Sensors monitoring different entrances must be given different
entrance numbers.

5.3.3. Live Mode

In Live Mode the measurement data of the individual sensors are displayed. This is
started after the activation of the SMC (see 5.3.2) by pressing key 'l’. The SMC then
responds as follows:

___________________________ LIVE MODE _____________________________
<r> Reset of already counted persons
<c> Configuration menu
<d> Display sensor
<e> End

The commands possible are displayed here, a brief description of which follows:

r Reset people already counted
c Call-up the configuration menu
d Select sensors displayed, e.g. 1 for sensors 1&2
e End Live Mode

The measurement data from the sensors are issued as follows.

a 0 0 1 ic 0 0 0 ip 0 0 0 oc 0 0 0 op 0 0 0
a 0 0 1 ic 0 0 0 ip 0 0 0 oc 0 0 0 op 0 0 0

Each line represents a period of 140ms. The measurement data are:

a Amplitude
ic Counts In
ip Person In, number of people counted In
oc Counts Out
op Person Out, number of persons counted Out

In each case 2 sensors and an imaginary sensor located between the sensors are
displayed. This latter counts people passing between 2 sensors.

Operating Instructions HUZ3 25 / 25

5. Operating the MSP3 – Firmware 1.x

The measurement data for the imaginary sensor are calculated as follows:

Amplitude = Amplitude of first sensor * Amplitude of second sensor
Counts In = Counts In of first sensor

Counts Out = Counts Out of first sensor + Counts Out of second sensor

Counts are added as from an amplitude of 30.

If amplitude “---“ is issued, communication with the sensor has failed. In this case
the cable connection to the sensor should be checked.

5.3.4. Control Counting

Under “Control Counting“ the people counted per entrance are listed. Control
counting is started after activation of the SMC (see 5.3.2) by pressing key 'c’. The
SMC then responds as follows:

_________________________ CONTROL COUNTING ________________________
<r> Reset of already counted persons
<c> Configuration menu
<d> Display entrance
<e> End

EN 1 i 0 o 0 EN 2 i 0 o 0 EN 3 i 0 o 0 EN 4 i 0 o 0

The commands possible are displayed above:

r Reset people already counted
c Call up the configuration menu
d Select entrances displayed (EN), e.g. 1 for entrance 1...4
e End control counting

Underneath, the people counted are displayed:

EN Entrance
i People In = number of people counted in
o People Out = number of people counted out

5.3.5. Automatic Calibration

Behind "Automatic Calibration“ there is an installation assistant to determine counting
parameters. This calls up all the setting parameters of the SMC and the sensors. The
counts are set automatically - in which each sensor is crossed 7 times per direction.

Automatic calibration is started after the activation of the SMC (see 5.3.2) by
pressing key 'a'. The SMC responds as follows:

____________________ AUTOMATIC CALIBRATION _________________________
<l> Delete last displayed value
<n> Next sensor
<e> End

HUZ address 1 (1..32)=

First the address of the SMC on the data bus is requested. If this is entered, or
skipped (ENTER or ESC), additional parameters are requested. After parameter
interrogation, the following is displayed on the screen:

Sensor 1
Assign sensor to entrance: 1 (1..12)=
Reverse 0 (0..1)=
Gain 50 (5..100)=
runs needed 7 in: 0 0 0 0 0 0 0 out: 0 0 0 0 0 0 0

For automatic calibration, "Sensor 1" must be crossed seven times is each direction.
Each measurement value (Count) is given in the bottom line. The last value
measured can be deleted by pressing key 'l’. When calibration of the sensor is
finished, the SMC responds with

counts in= 43
counts out= 46
Save values? 1: (0..1)=

If a '1' is now entered, the new parameters are saved. Pressing a '0' rejects the new
parameters.

By pressing key 'n' (Next Sensor) the sensor is skipped.

If no sensor is connected to the present sensor port, „Sensor 4 Not Connected“
is displayed.

If "Frame Error“ is displayed behind the parameters, the last communication with the
sensor failed.

In order to alter the parameters of a sensor, the sensor no. (1..12) must be entered
and confirmed with ENTER. The SMC now asks for the sensor parameters of the
series.

Initialise sensors

Init Sensors starts the initialisation of all sensors connected. The firmware version of
the sensors is requested. Then all ports where no sensor is connected are set to "Not
Used“.

NOTE: If a sensor is set to Not Used, no sensor interrogation will be

started on this port. Sensors connected subsequently will not be
recognised!!!
If the version number of a connected sensor is not read out
correctly, communication with this sensor is disrupted (cable
defective, sensor defective, plug connections, ...).

5.3.7. Sensor measurements, control counting

The points described here should ensure that people are counted correctly. If it is not
possible to keep to the limit values described here (e.g. due to disruptions) this
should be documented in the setting/installation report.

The sensors are measured in the following sequence:

1. Set any existing fans, blowers, ... at the entrance to the standard setting
(according to personnel). The setting should be documented in the setting
report.

2. In LiveMode check that no communication errors occur with the sensor.

3. In LiveMode set the amplification so that

o Amplitude remains < 10 when no person is crossing the sensor field.

o When a person of average size crosses, 40..50 counts are measured.

o When a person crosses, no counts are measured in the other direction.

Example: one person crosses the sensor in the inward direction, but
CountsOut are measured in addition to CountsIn.

4. By means of Automatic Calibration determine the threshold value for
CountsIn / CountsOut.

parameters (Gain, CountsIn, CountsOut) according to the count deviations.
The way in which the control count is to be carried out is described below.

o Increase threshold value for Counts if too many people are counted

o Reduce threshold value for Counts if too few people are counted.

The control count is carried out as many times as necessary to achieve this.

Operating Instructions HUZ3 31 / 31

6. Operating the sensors

5.3.8. Agreeing control counts

In the control count, "25 people / sensor“ are counted.

Example: Entrance with 2 sensors Î control count to 25*2 = 50

Entrance with 4 sensors Î control count to 25*4 = 100

In the control count, only customers are counted (not in-house personnel). People
are counted as follows:

- People under 1.40m are not counted (0 people)

- People with children / shopping trolleys count double (2 people)

- Wheelchair users count double (2 people)

If the entrance to be measured has low traffic (few customers), personnel should be
included if possible. The way in which the control count is carried out should be
documented in the installation instructions.

The control count has been achieved when the following criteria have been met:

- During the control count the count result of the SMC deviates from the actual
value by fewer than 5 people.

- After the control count, the count result of the SMC deviates by less than 5%
from the actual count.

- The count trend of the SMC is the same for both directions of counting (not
that too man people are counted in but too few people are counted out).

5.3.9. Firmware update for the SMC

For the SMC3 Firmware Update, the "MegaLoad“ programme from the MicroSyl
company (www.microsyl.com) is required.

The update can be done via RS232 or RS485 (Bluetooth is not supported). The cable
connection should not be longer than 10m. The following baud rates are supported
for this:

RS232 all baud rates
RS485 9600 baud

Update with 9600 baud

In order to carry out the update with 9600 baud, the MegaLoad programme only is
required.

The new firmware (as a hex-file) is selected under Open.

The corresponding Comm Port, and 9600 bps, is selected under Comm Setup.

Operating Instructions HUZ3 33 / 33

6. Operating the sensors

The " Monitor“ button is used for opening an Input-Output window. The SMC can be
operated as on the terminal.

After activating the SMC (see 3.1.2), the Update Menu is opened by pressing key 'u'.
The SMC then responds as follows:

================== Firmware Update Version 1.0 =====================

Select Source: 0=RS232 / Bluetooth
1=RS485
source =

The source is requested here (RS232 / RS485). After entering the source and
confirming this Enter, a security code (5247) is requested in order to confirm the
execution of the update. After this code has been entered, the update is started.

With MegaLoad, progress is displayed under Message. With 9600 bauds, the update
takes about 1 minute and has been successfully completed when "All Done in
87433ms“ is displayed under Message.

If the update is not to be carried out, this can be interrupted with ESC.

Newer versions of MegaLoad:

With newer versions of MegaLoad there are additional options in the form of check
boxes. These must all be deleted!

Operating Instructions HUZ3 34 / 34

6. Operating the sensors

Update with other baud rates

As the update takes quite a long time with 9600 bauds, an even higher baud rate can
be used with an RS232 connection. For this, the terminal is required in addition to the
"MegaLoad“ programme.

The baud rate for updating is selected under MegaLoad (e.g. 115200bps).

With 9600 bauds, the Update menu is called up in the terminal as described above
and all inputs are carried out for starting the update.

After entering the security code 5247 and confirming this by Enter the connection to
the terminal must be cut and restored by MegaLoad.

The update starts with the baud rate selected.

5.3.10. SMC Error Log

With HUZ2 versions 90 and 91 there is an error protocol which is also called up from
PCSoft 6.2.

The file contains information on any errors which may have occurred with the SMC /
sensors, and what these were. In addition the ErrorLog contains information on when
the SMC was switched on.

The file structure will be described first of all, and then some examples are given of
the possible entries.

6.2. Auto-test

As from sensor version KF32.2, auto-testing of the sensor is possible. This auto-test
measures the noise level of the radar module for approx. 20s and issues the
measurement result. The auto-test is carried out as follows:

1. As the auto-test measures the noise level for approx. 20s, the sensor field
must be free of movements during the measurement. For this, the sensor is
laid, with the antenna, on a vibration-free surface (e.g. on the floor).

2. As with the firmware update, connect the sensor direct to the PC and start the
terminal.

3. Press 'x' approx. 6 times in succession. The sensor responds with

KF-Sensor 32.3 Boot

u = Firmware Update
s = Selbsttest

4. The auto-test is started by pressing the ’s’ key. The following appears

=== Start Selbsttest ===....

on the screen. The dots shown progress.

5. After approx. 20s the sensor gives, e.g., the following measurement result:

CH1: max=523 , min=502 , diff=21 , avr=512
CH2: max=542 , min=476 , diff=66 , avr=503
Modul OK

The top line shows the measurement data from channel 1, the bottom line
from channel 2 of the radar module. Max/ Min is the highest/lowest value
measured, Diff if the difference and Avr the average value measured.

The auto-test is complete when

CH1 Diff < 28

A1 - Separating an installation cable

Structure ( I-Y(St)Y )
The installation cable used
in communications and
security technology consists
of a PVC sheath. Beneath
this there is a metallic plastic
shield providing static
protection and a plastic core
wrap. Between these is the
tracer wire which is
connected to ground.
Underneath are the double
conductors (pair stranding)
which are arranged in
layered stranding.

When the installation cable
is to be used, the sheath,
the static protection and the
core wrap must be removed.
A knife is used for this. Care
must be taken here to ensure that the tracer wire is not broken and the double
conductors are not damaged. When removing the sheath it is important that the core
does not come apart. It is best if the core is held together with a cable tie or wire.
When separating, the double conductors are twisted together and grouped into
bundles (5 double conductors in each).

A3 - Known errors with the SMC firmware

A3.1 –SMC Version 1.1

Operator output changeover changes from RS232 to RS485

With the SMC, the RS232 and RS485 interfaces are independent of each other. If the
SMC is activated via RS232, then this also responds on the RS232 line only (there is
no data output on the RS485 interface).

With Version 1.1. it is possible, due to a fault on the RS485 line, data call-up by the
PC, that output is switched to the RS485 port. This has the following effects on the
user side:

- In ControlCounting, the SMC does not appear to continue counting

- In LiveMode, there is no further data output

- The SMC does not appear to be reacting any more

Output is switched back to the RS232 interface by pressing any key (e.g. Esc).

In the configuration menu, Entrance=241 is displayed for one sensor

According to InitSensors in the configuration menu, Entrance=241 is set for the ports
used (no sensor connected), in order to identify this for PC data call-up.

If a sensor is added, Entrance must be set to the new value manually.

Entry=241 is displayed in the ErrorLog

This value is the equivalent of Entrance=0, meaning no sensor connected.

Errors are displayed in the ErrorLog for unused ports

These errors can be ignored.

A4. Optional: Connection via Bluetooth

Using Bluetooth a wireless connection to the SMC is possible during the
configuration and parameter setting phase of the counting equipment. This means
that the expensive RS232 cabling, which can be a nuisance for the client, can be
dispensed with.

The Bluetooth modules used with Publicount have a maximum breadth of range of
100m in the open (Class 1). In real installations, when the SMC is installed behind
walls, cover plates etc., the remaining breadth of range is around 30..50m.

A Bluetooth adapter is required for each SMC, as well as one for the service PC
(Notebook) locally. From the PC outwards, a cable-free connection arrangement to
each SMC is then possible.

Once a Bluetooth connection has been set up between PC and SMC, the PC and
SMC behave as they would if connected together by an RS232 line (cable back-up).
However, setting up a Bluetooth connection does require a few stages, which will be
illustrated below.

A4.1. Producing the connection to the SMC

1. Setting up the SMC for Bluetooth:

Disconnect the SMC. Plug the Bluetooth module into the RS232 port and
connect it up again (mains cable). The module is recognised by the SMC
immediately it is switched back on and configured. Plugging in the module with
the equipment running is not permissible.

2. Setting up the PC:

Connect the Bluetooth adapter to the USB or serial interface (RS232) and start
the "Hyper-Terminal“ programme. The Bluetooth module should respond with
an "OK " message.

3. Interrogation of existing Bluetooth equipment:

In order to be able to set up a Bluetooth connection, you need to know what
other Bluetooth equipment is located within this environment. The command
“at+btinq?“ is used for this. The PC module may respond with the following
outputs:

000B5316118C,HUZ-3,001F00
000B53160DB0,HUZ-3,001F00
000B53160EF8,HUZ-3,001F00

The response means that 3 Bluetooth SMCs are located in the immediate
vicinity. The first 12 digits here represent the Bluetooth module address by
means of which access to the relevant SMC is possible.

Operating Instructions HUZ3 52 / 52

Appendix

4. Entering the password, making the connection :

The Bluetooth connections used by Publicount for the SMC are coded for
security reasons and provided with a password. Setting up a connection
between PC and SMC is only possible if the password and Bluetooth address
of each SMC are known.

The following example of a sequence produces just one Bluetooth connection
to an SMC:

at+btkey=”HUZ3-0408-001”
atd 000B5316118C

The first command sets the password on the PC side. It is identical to the
serial number of the relevant SMC and has the format <HUZ3-mmyy-number>
(example: “HUZ3-0408-001“). The second attempts to set up the connection
between PC and SMC. The PC module should respond with “OK“ to both
commands. If the connection is made, the module then issues the message
“CONNECT 000B5316118C“, or otherwise “ERROR“.

The connection to the SMC has now been made.

A4.2. Other commands

Break connection:
Once made, a connection can be broken again with the following command
sequence:

+++
ath

The PC module should respond with “OK“ to both commands. If the connection is
then finally broken, “DISCONNECT“ should then be set. The PC module is now free
for a new Bluetooth connection.

Restore last connection:
With the command “atd“ the last connection used is restored. All connection data
remain in existence, even after the Bluetooth module has been switched off.

Reset the PC module
The PC module can be reset by means of the command "at&f". After resetting, the
module again responds with “OK“. If the Bluetooth module does not send a message
to the PC, a Reset must be carried out.
