MATRIX R2 CAN Installation manual
1 General
1.1 On this document
This document describes the installation of the IRMA passenger counting system IRMA MATRIX
(sensors and IRMA gateway) with CAN cabling as well as the connection to the on-board
computer.
MATRIX sensors are designed for installation above passage areas. They can be mounted in the
upper part of door trims (coves
DIST500-F in the flush mount version and DIST500-A in the surface mount version).
The connection of the MATRIX sensors to the power supply and the CAN BUS will be made with
specially developed connectors which are available in different versions with different
functionalities and properties. For an overview see section 12.1.2 on p. 64.

) either flush countersunk or on the surface (sensor versions
The IRMA gateway converts the door statuses provided by the door contacts into control signals
compatible with a CAN BUS for switching the sensors and thus the counting process of the
respective doors on and off.
The CAN signal is adapted to different software and hardware components such as IBIS, RS485.2,
J1708, switching outputs, RS232, thanks to the use of different IRMA gateway versions.
If the counting system is operated without an IRMA gateway, the control signals for starting and
stopping the counting operation at each door are sent by the on-board computer, see e.g. Fig. 48,
p. 73.
For installation of the system please follow the individual operations described in the document.
Items or steps not applicable or already clarified may be skipped. For more detailed information
on the components referred to in this document please see the data sheets of the individual
components and the "M12 components for IRMA sensors on the CAN BUS" catalogue on our

2 Important information when working with IRMA
MATRIX sensors
IRMA MATRIX sensors must only be installed by qualified expert staff trained by iris-GmbH
who observe the pertinent regulations and the installation manual.
In all considerations with regard to installation positions and orientation, it is assumed
2.1.1 New service software version required
Before starting the configuration of the IRMA MATRIX sensors, perform an update of the
"DIST500-Configuration Tool" service software to version "3.9.6.187" or higher. For more
detailed information on the software update see section 8.2.1 on p. 47.
2.1.2 Firmware
Important note:
Please bear the following in mind for firmware updates via an on-board computer!
Firmware versions having "1" as the first Fig. of the version designation must not be
installed any more.
The sensor firmware is continuously developed in order to keep up with technological
progress. As downward compatibility with the predecessor version is ensured from
firmware versions with "2" as the first Fig. on, different firmware versions in different
deliveries are by no means a functional restriction. The latest firmware version is: D5FC DIST500_Application_2.1.312.6797 - CE_CF_D0_D1_D4_D5.d5fc.
If a consistent firmware version is to be ensured for one order comprising several
deliveries, please indicate this requirement when placing your order.
2.1.3 Comparison of old and new counting firmware
The new firmware file
• D5FC-DIST500_Application_2.1.312.6797-CE_CF_D0_D1_D4_D5
added new parameters to the “Ethernet” and “Installation” tabs.
In the old firmware

3 Preparation of the installation
Careful preparation is required for successful and trouble-free installation of the IRMA
MATRIX passenger counting system. As the type of installation depends on the individual
conditions in the vehicle entrance area, the installation conditions must be checked in
preparation of the installation. The options for power supply and the connection to the onboard computer (on-board computer/unit) of the vehicle must be clarified before the
installation starts.

3.1 Vehicle data sheet
iris-GmbH offers a vehicle data sheet for vehicles which are to be equipped with the IRMA
passenger counting system. This data sheet serves to collect the main installation
conditions. Based on the information from the vehicle data sheet we can properly plan
your project in advance, thus helping you select the optimal components for your vehicle.
For a download of the vehicle data sheet please refer to our website
https://www.irisgmbh.de/wp-content/uploads/FL-Datenblatt-zur-Auswahl-derIRMA_0.2.pdf. A proved and tested help for us are photos of the coves (door trims) above
each of the doors with the doors closed and open (see alsoFig. 3). They show the space
available in each case and help select the correct sensors..
For each vehicle type, each year of construction and each equipment variant you need to
fill in individual vehicle data sheets which you return to the contact person of iris-GmbH
along with the pertinent photos.
3.2 Clarification of specific installation conditions
Please clarify the following circumstances well in advance of the installation as such:
• Does the vehicle lighting system or door mechanics interfere with the installation of the
sensors? An important help is a photo showing the installation situation in the upper
part of the door trim (see also Fig. 3.)

R2 CAN Installation manual
• Have optical door safety systems been installed in the vehicle?
In exceptional cases IRMA and the door safety systems can influence each other. This
needs to be checked. See the document: KDAN_AppNote_Türsicherung_0.1_en.pdf
• Is the presently applicable max. installation height of the sensors of 2.40 m exceeded?
• Are there steps in the entrance area?
• Which are the height and width of the doors? In the event of unfavorable door
dimensions (very wide and low doors), the installation of 2 sensors can provide optimum
coverage of the field of monitoring. This decision must be made in consultation with irisGmbH.
• Are there objects in the door area permanently interfering with sensor operation while
the doors are opened and closed?
Such interfering objects are e.g. handrails, separating and guiding surfaces, seats located
in the door area or projecting into it, etc. It is possible that the reflecting surfaces of such
objects interfere with the measurement and thus distort the counting results.
Possible measures to be taken:
If there are interfering objects in the close-up range of the sensor, their influence can be
minimized by suitable modifications of geometry such as: observing a distance to
vertical guiding elements or modifying the surfaces, e.g. slanting or blackening them.
• How are the doors opened?
• Are the doors are opened automatically via an electric-pneumatic or hydraulic
system?
• Are the doors opened manually by actuation of a pushbutton in the passenger
compartment or by the first passenger boarding the vehicle or alighting from it by
pushing the door open or cranking it open?
• Are the doors opened in any other way?
Which one?
• How is the door status signalized?
• For counting, the sensor needs to receive an activation signal before.
Normally the activation and deactivation signals are transmitted by the on-board
computer in the form of a pre-defined message.
• Has the on-board computer received the necessary information on the door status
for sending such a message?
e.g.
• Door release,
• Green loop (ATG signal),
• Status for each door
• If the on-board computer cannot provide the technical option of sending
such a signal, please contact iris-GmbH to clarify possible alternatives.
• How is the 24 V DC voltage supply ensured?
• The distribution of the vehicle-provided on-board voltage supply does not form
part of the normal scope of delivery by iris-GmbH.
Is it made available at each door before the start of the installation?

• The supply voltage must not fall below 16°V, e.g. with an excessive number or
consumers or with the motor switched off.
• The optimal solution is a switch-off delayed by approx. 30 minutes so that
counting is possible even with the engine (and/or the on-board network)
switched off.
• Is a time-delayed power supply via the on-board network possible or
• does a timing relay need to be connected to permanent plus (see also
section 6, p. 34).
3.2.1 Important information on sensor placement
• Install the sensors in the centre of and as closely as possible to the door.
• The maximum distance between the sensor and the vehicle inside wall must not exceed
20 cm. Mounting sensors at a larger distance from the door must be agreed with irisGmbH before the installation.
• Install the sensors on a horizontal surface. The maximum permissible deviation from the
horizontal plane is ±5°.
If the upper door trim does not allow direct mounting, you can achieve the required
horizontal sensor position using suitable sensor mounts. Please agree any use of sensor
mounts with iris-GmbH before the installation.
• With such a sensor mount, the sensor must be placed no more than 5 cm above the
lower end of the vehicle wall.
• Objects standing vertically in close proximity to the sensor up to a distance of 3 cm from
the sensor surface can impair the counting result and must be avoided.
Fig. 4: Maximum distance to the end of vehicle inside wall
• The installation orientation must be observed in all cases; it complies with the markings
on the rear of the sensor, see Fig. 5:

• “Interior" must face inwards when mounted.
• In the sensor's close-up range of up to 3 cm from the sensor surface there must not be
any horizontal objects which might affect the counting result.
Fig. 5: Label on the rear - Observe mounting orientation!
3.2.2 Installation in center position above the door
Generally one sensor is used for each door. It is installed in center position in the upper
area of the door trim at a right angle to the stream of the passengers boarding the vehicle
and alighting from it.
Clear passage width

Open door leaf
Fig. 6: Determination of the center of the clear passage width
First you need to determine the clear passage width of the door. Objects projecting into the
passage must be taken into consideration when measuring (see item (3) in Fig. 6).

On typical bus doors being e.g. 2.05 m high and 1.30 m wide and with the sensor in the
optimum position in the center of the upper door trim, the entire (clear) passage area to be
monitored is covered by one sensor.
If it is not possible to install the sensors in the centre of the doors or of the doors are very
wide / low, the installation position and the number of sensors for each door must be
discussed and agreed in advance with iris-GmbH.

The sCON (connector for sensors) was developed particularly for IRMA MATRIX sensors for
the connection to the power supply and data transmission units.
Depending on the sensor variant, different sCON variants are available, differing in their
geometry and function:
• The sCON-S (standard) provides for the electrical connection of IRMA MATRIX sensors.
It can be used for all IRMA MATRIX sensor versions. The sensor interfaces are routed
outwards in the form of connecting lines with M12 connectors.
• The shape of the sCON-F-12 is flat and adapted to the sensor geometry which allows
the housing to simultaneously provide for mounting and electrical connection of the
sensors. This shape permits a reduction of the required installation depth behind the

. The sCON-F-12 is equipped with interfaces in the form of M12 connectors.
cove
The differences in the required installation depth due to the use of different
sensor/connector combinations are show in section 12.1.2 on p. 64.
Please note the sensor/connector combinations possible. See overview in Table 3.

4.2 Installation of the IRMA gateway
6 holes with a diameter of 4.8 mm each are provided on the IRMA gateway housing for
mounting to the vehicle. At least 4 of these holes must be used for screwing down the
housing.
When installing the IRMA gateway, see to it that sufficient space is available for connecting
the connectors (space required approx.: 200 mm x 226 mm).
When installing the IRMA gateway, a low-resistance connection must be established
between the IRMA gateway housing and the vehicle chassis. This can be achieved by
screwing the IRMA gateway directly to the vehicle chassis (electrically conductive material).
Use a tooth-lock washer for mounting.
.
If the low-resistance connection cannot be realized in this way for reasons of standards or
because the chassis is non-metallic (e.g. glass-fiber reinforced plastics), an additional
grounding cable must be fitted (yellow/green, conductor cross-section >4 mm²,
recommended length: ≤ 25 cm), see Section 5.3.3, p. 31.
4.3 Numbers of IRMA MATRIX sensors per door
The following diagram (Fig. 15) serves to determine the number of sensors for each door,
depending on the height and/or width of the door.
1 IRMA MATRIX sensor must be used if the intersection point of door height and door
width comes to sit to the left of the blue line.
2 IRMA MATRIX sensor must be used if the intersection point of door height and door
width lies between the blue and red lines.
The values indicated are recommendations - in case of deviations please contact irisGmbH.

5.2 Installations in accordance with EN 50343 (railway vehicles)
For installations in accordance with EN 50343 (for railway vehicles) cables of the iris cable
characteristic "K3" must be used (see section 5.1). This cable is additionally shielded, which
yields sufficient electrical isolation.

R2 CAN Installation manual
Use cable clips to secure all cables every 30 cm. The cables must not be fixed to parts which
can normally be shifted or replaced during maintenance.
When fixing the cables in their positions the minimum distance to power lines/conductor
rails of 20 cm and to battery or binary control lines of 10 cm must be observed.
The cables must be laid with sufficient reserve length so that they can be re-fitted to
connectors at least three times.
When laying the cables the minimum bending radii given in the "Components for IRIS
sensors on the CAN BUS" must be observed.
The shield of the cabling must be connected to the potential of the vehicle chassis as often
as possible via a low-resistance connection - i.e. at each sCON connector. This is done either
by directly mounting it to the chassis or by the additional installation of chassis grounding
cables.
Yellow-green cables with a line cross section of 4 mm² must be used as grounding cables
(see section 5.3, p. 29 et sequ.).
At all clamps and disconnectable plug connectors the individual cables must be identified
in a practical manner. The individual cables are to be marked with a label attached to the
cable at approx. 10 cm from the connector.
Requirements to auxiliary material such as cable clips, marking clips, shrinkdown tubing:
Only such auxiliary material must be used which is resistant to the conditions to which the
cables are exposed, e.g. resistance to diesel fuel. Its fire behavior must comply with the
requirements of EN 45545.
For the operating characteristics, cable lengths, technical data and item numbers please
refer to our catalog "IRMA MATRIX components for Ethernet installations".
5.3 EMC-compatible installation/grounding in accordance with EN 50153
In order to achieve EMC-compatible installation in motorized vehicles (E1, e1 permit) and
railways (EN 50121-3-2) and to observe EN 50153 (Railway applications - Protective
provisions relating to electrical hazards), it must be ensured that the connection between
the housing of the sensor and IRMA gateway and the chassis potential is conductive. For
this purpose an additional connection is installed between the device housing and the
chassis. This is realized either by screwing the housing down directly on bare and uncoated
metal surfaces or by the installation of an additional grounding cable.
The grounding cable (yellow/green, line cross section 4 mm²) should be as short as
possible. We recommend not exceeding a length of 25 cm, if possible. It is installed
between the sCON or gateway housing and a suitable point on the chassis (see section
5.3.1, 5.3.2.).

5.4 CAN cabling
All available CAN components are shown in the Annex in section 12.2 p. 65 et sequ.
Connection examples can be found in section 12.3 from p. 68 on.
• An IRMA CAN BUS is a line-type BUS with short branch lines to the BUS devices.
• The sensor is connected to the IRMA CAN BUS with special connectors (sCON).
• The BUS - sensor connection of the sCON-S (standard) is a branch line from its
CAN interface to the sensor connection. Any further sensors are connected to the
BUS via M12 H couplers.
• sCON-F-12 is equipped with two CAN connections. In addition to the electrical
connection of a sensor to the IRMA CAN BUS they also serve as a Y coupler, due to
their internal wiring. The BUS is continued from the second CAN connector to the
next sensor. At the last sensor a termination is installed.
• IRMA CAN sensors are connected to the CAN BUS with 5-pole M12 CAN connectors (m/f)
(for a description of the CAN connectors see section 1.3.1, p.9).
• From the data transmission point of view the maximum line length of the IRMA-CAN
BUS is 40 m.
• H couplers ensure branching (branch line) to up to two CAN BUS devices per coupler.
The branch length describes the maximum length between a device (sensor, IRMA
gateway, CAN USB converter) and the CAN BUS (coupler).
• The maximum branch length (at 125 kbit/s) is 2 m.
• Unused branches on H couplers must be closed using M12 plug screws or closing caps.
• All devices (IRMA gateway, sensors and USB converter) can be located at any place in the
IRMA-CAN BUS.
• The individual devices are interconnected with K-M12CAN-XX-xm CAN cables and M12
H couplers of the CAN type ("XX"= 03 for K2
lengths available).
Special care is required when connecting an H coupler. After insertion of the positivelocking plug-in connection it must be possible to tighten the knurled nut of the connector
simply by hand. Otherwise the connection is wedged and must be opened again.
When screwing a connector to an H coupler the maximum torque of 0.4 Nm must not be
exceeded.

R2 CAN Installation manual
If cables in direct proximity to H couplers are tied up, ensure that the connections are not
bent. There is the risk of the connectors becoming wedged which will result in interruption
of the contact and destruction of the plug-in connection in operation.
Therefore the tightening of e.g. a cable clip is permitted only on the solid base body of the
H coupler or at a distance of approx. 15 cm from the plug-in connectors.
Generally the beginning and the end of the maximum IRMA CAN BUS must be fitted with a
resistor (terminator). For this purpose use a termination cable and a termination connector.
Their functionality is identical.
• The termination connector (m) of the CAN type is connected to the open end of
the last coupler if the power supply and the IRMA gateway are located at the
beginning of the CAN BUS (see e.g. Fig. 44, p. 69).
• In the event of the installation of the IRMA gateway in the middle of the line, the
termination connector is connected to the last H coupler (see e.g. Fig. 45, p. 70).
• The termination cable K-A21-M12CAN-TRoP-XX-32cm is installed between the
IRMA gateway and the M12 cable system of the CAN type if the power supply and
the IRMA gateway are located at the beginning of the installation (see e.g. Fig. 44,
p. 69).

6 Power supply
The nominal voltage of the sensors is 24 V. If a gateway is installed, it must also supplied
with 24 V DC. The supply of 12 V DC is not permissible; a step-up transformer is required.
Direct connection to permanent plus is not permitted by VDV 457.
The connection to the power supply must be protected by a fuse or an automatic circuit
breaker (5 A, quick-acting - for up to 8 sensors and IRMA gateway).
Counting must be ensured even with the vehicle engine switched off (e. g. at the terminal
stop). For this purpose it is necessary to have the power supply of the sensors after-running
for approx. 30 minutes.
If no 30-minute power after-running can be provided in the vehicle, a timing relay which
can be set to at least 30 minutes (dropout/OFF delay) must be used for the after-run of the
power supply. The switch-off delay of the timer relay is activated at the moment the
ignition voltage is no longer applied.
A timer relay with e1 approval is available as optional accessory.
This sketch shows a possible switching variant in the motor vehicle sector- Fig. 22.

The 4-wires can be used for power supply (wires: red and black) and/or for connection to
the CAN communication of the BUS (wires: white and blue).
If certain wires are not required, they must absolutely be insulated in order to avoid any
accidental contact resulting in communication disturbances of the sensors.
If the power is supplied at the beginning of the CAN BUS, the number of sensors is limited
to a maximum of 4 (for installation examples of the power supply at the beginning see Fig.
44, p. 69 and Fig. 45, p. 70).
If the power is supplied in the center of the CAN BUS, this limitation does not apply (see Fig.
45, p. 70 and Fig. 46, p. 71).
For installations with more than 4 sensors we recommend connecting the IRMA gateway
and the power supply in the center of the BUS.
Generally the following applies to operation of 4 sensors:
In case of continuous operation in the lower limit range of nominal voltage (16.8 V), the
permissible cable length is reduced from 50 m to approx. 22 m. The effective cable length
can be reduced by connecting the power supply in the center of the CAN BUS. If longer
cable lengths are required, the permissible cable length can be extended by connecting an
additional power supply. It must be ensured that there are no potential differences
between the power supply systems.

7 The IRMA gateway as an interface adapter
The IRMA gateway serves as an adapter between the CAN interface and other interfaces.
Depending on the IRMA gateway version, the following interfaces are possible:
• IBIS interface with unit IRMA-Gateway-4-IBIS, see section 7.1.2 , p. 40
• RS485.2 interface with unit IRMA-Gateway-4-RS485.2, see section 7.1.3, p. 40
• J1708 interface with unit IRMA-Gateway-3-J1708, see section 7.1.4, p. 41
• RS232 interface with unit IRMA-Gateway-3-RS232
• switching outputs with unit IRMA-Gateway-0-OSW4
7.1 Door signal input and on-board computer connection
The cable for connecting the IRMA gateway with the door signal inputs and the on-board
computer is connected to connector "V".
The door signal input provides the information on the door status, i.e. whether the door is
open or closed. Passenger counting is to be interrupted while the door is closed! For this
purpose it is necessary to have the door signal available without delay.
Table 6: Logical evaluation of the door signals
Door open/closed
logically positive logically negative
Door open (including door
+9 ... +32 V DC 0 ... +6 V DC
opening and closing
"Logically negative" is the preferred alternative if the sensor is to count passengers also
when no voltage is applied at the door signal input (e.g. if the ignition of a bus is switched
off). The door contact logic is configured in the sensor (section 8.2, p. 47, "Door Polarity").
The IRMA gateway offers two options for evaluating the door signals which can be
activated by using different cable sets:
1. Potential-free switch - Here an internal voltage (generated in the IRMA gateway) is
applied and the switching status evaluated accordingly.
2. Evaluation of voltage levels - Here voltages from the vehicle are evaluated, e.g. from the
door control.

8 Sensor configuration
8.1 Connection to the service PC
For the configuration a laptop with Windows XP, Vista, 7 or 8 is required.
The service laptop is connected either
• via a CAN USB converter (accessories) to an USB interface on the PC
(see section 8.1.1)
• or via a connector for MATRIX sensors equipped with a CAN interface and an ETHERNET
interface, such as
• the connector of the CON-S-CAN-ETH-23-K2-x-y type (see section 8.1.2.1, p. 45)
• or the sCON-F-12 (see section 8.1.2.2, p. 45).
8.1.1 PC connection via CAN-USB converter (accessory)
A CAN-USB converter transfers the CAN signal to the service PC. We recommend using the
CANproUSB by company "Softing". In order to use the CAN-USB converter on the service PC,
the pertinent driver must be installed on the PC. If you are working with the CAN-USB
adapter, we urgently recommend that you use the latest version of the CAN driver by
company "Softing":
CAN_Driver_API_Manual_LeanCANopen_Programming_Samples_Windows_8_7_Vista_XP
_V5.17.015_130617_01.zip
For connecting the converter the CAN BUS is opened at any point and the CAN-USB
converter inserted into the bus with a SubD-9/M12 adapter without termination (see Fig.
23). A coupler connection which is not in use can be opened for this purpose, or a new line
is installed with an additional coupler (see Fig. 24). Then connect the converter's USB
connector to the service PC. The CAN-USB converter can "listen in" without interrupting the
communication to the on-board computer.

The Extended data sheet for IRMA MATRIX contains a detailed description of the
nameplate.
“Door Address/Door Contact Input (1…4, for Gateway only)” – The door contact input
starts or stops the counting operation of the IRMA MATRIX sensor.
In case of an existing CAN gateway installation the door contact input corresponds to the
door signal inputs of the gateway. The corresponding value must be between 1 and 4 and
is assigned to just one sensor or one sensor group.
With an Ethernet installation the setting value for the “Door Address” is, as a rule, identical
to the “Function Area Address” (FA).
“Door Close Delay” - (only on the CAN BUS with gateway) - The parameter determines for
which period of time after the “Close door” signal the door will still be monitored and
persons can be counted (setting range: 0 to 65,535 ms = 1 min 09 s).
Determine the time between the door closing signal sent by the on-board computer and
the actual mechanical closing of the door and enter this value.
“Door Polarity” - (only on the CAN BUS with gateway) - Here the door contact polarity can
be selected as either “logically positive” or “logically negative”,
logically positive meaning: 0 V = “Door closed2; 24 V = “Door open”
logically negative meaning: 0 V = “Door open”; 24 V = “Door closed”
If several signal sources are present on the vehicle, set "negative"8, since the counting is
still active when the door is open and the ignition is switched off.
“Mounting Height” - indicates the mounting height of the sensor in mm.
Drop a perpendicular from the sensor centre to the floor and mark the foot of the
perpendicular on the floor with an adhesive marker.
The distance from the sensor to the adhesive marker is the mounting height.
Measure the distance and enter the value measured.

“Left Wall Distance” – is the left-hand sensor monitoring area up to the left lateral
boundary in the vehicle interior.
Set 0 mm if there is no obstacle between the adhesive marker and the left lateral boundary
when the door is open.
“Right Wall Distance” - is the right-hand sensor monitoring area up to the right lateral

order to differentiate between boarding the vehicle and alighting from it. If the installation
distance exceeds 20 cm, absolutely contact iris-GmbH.
Measure the distance and enter the value measured.

“Rotation Angle X”- is the inclination angle of the sensor around the X axis when the
vehicle is stationary on a level plane. Sensors directed towards the inside have a positive
angle. This angle must not be > 5°; otherwise the counting accuracy is reduced.

9 IRMA gateway configuration
9.1 Connection of the IRMA gateway to the PC
Your PC must have free USB or RS232 interface
• A PC without a free RS232 interface needs to have an additional USB RS232
converter. (We have had good experience with converters with an FTDI chip set
FTDI US232R-100 - available as accessory).
• After installation of the relevant drivers the USB interface is detected as a COM
interface.
Use service cable K-A21-C-RS232-o1-xxxx (7-wire cable, available in lengths of 3 m, 10 m,
15 m). Connect the service interface "C" of the analyzer with the RS232 interface of the
service P!
9.2 Configuration of the IRMA A21 gateway with the "A21 Assistant"
The service software for the configuration of the IRMA gateway is the "A21-Assistent"
which is a subprogram to the "IRMA-A21-Windows_Release 5" software. The service
software program is available for downloading on
documents/service-software/ by the name of "IRMA-Setup_Release_5.x.x_User.zip". It will
be installed on the service PC automatically.
The "A21-Assistent" is a subprogram of the "IRMA-A21-Windows Release 5.x.x" service
software.
Start the "A21_Assistent" software:
Select the "Windows button" on the PC desktop. Open the program directory "IRMA-A21Windows Release 5" by clicking on it (see Fig. 40 on the left, p. 56).

10.2 Test ride/signal recording
A test ride with signal recording requires an Ethernet connection to the service PC. The
band width of the CAN BUS is not sufficient for transmitting 3D graphics data. For the PC
connection via Ethernet it may be necessary to change the connector to a version with an
Ethernet interface. See section
It is, however, possible to check the counting accuracy by directly connecting a laptop to
the RS232 service port of the IRMA gateway.
The test ride can be made using the "IRMA TestRide" software tool.
For a download of the "IRMA TestRide" service software please refer to our website:
https://www.irisgmbh.de/en/technical-documents/service-software/
It is downward compatible with the predecessor version and should be updated at regular
intervals (software revision at the moment of issue of these instructions: 2.8.1.37).
8.1.2 "PC connection via Ethernet interface", p. 44.
.
"IRMA TestRide" is a software tool determining the accuracy of the counting operation.
Furthermore, it stores graphics data from the sensor helping to check and improve the
system installed, if necessary. An intuitive input mask enables manual recording of the
counting results. The comparison between the manual counting data and those recorded
automatically then allows a conclusion on the accuracy of the passenger counting system.
The relevant instructions "KunDok instructions for IRMA TestRide" describe the individual
steps of operation: https://www.irisgmbh.de/en/technical-documents/service-software/
11 How is the optimum counting accuracy achieved?
Optimum counting accuracy is only possible if the following facts and conditions are taken
into consideration:
• Any disturbances caused by external infrared signals must be eliminated by taking
adequate measures in cooperation with iris-GmbH.
• If problems occur during installation, please inform iris-GmbH.
• The sensor must be installed in its optimum position:
• The maximum installation height of the sensors of presently 2.40 m must not be
exceeded.
.
• The sensor is mounted in such a way that passengers in an upright and natural
body position can pass the sensor field of view in both directions.
• Placement in the middle of the door area, perpendicular to the flow of passengers
entering and leaving the train;
• On installation, the correct orientation of the sensor was ensured (see Fig. 5, The
marking "Exterior" faces toward the outside).
• The sensor is placed as closely as possible to the vehicle wall, but at a small
distance from the vertical separating and guiding surfaces (mounted in a range of
3 cm to 20 cm from the vehicle wall).

• The passengers show purposeful behavior and can mount the vehicle and alight from it
walking upright. If the passengers jump and skip, this hampers optimum counting; the
same applies to persons mounting the vehicle and alighting from it between stops
without a platform compensating the height difference.
R2 CAN Installation manual
• The sensor must be installed horizontally. The maximum permissible deviation
from the horizontal plane should be < ± 5°.
• On doors with special dimensions (installation height < 1.90 m and very, very wide
door areas) the installation must be performed in consultation with iris-GmbH. If
necessary, 2 sensors are installed above the door.
• In the sensor's close-up range of up to 3 cm there must not be any horizontal
vehicle parts such as separators, stationary parts of the mechanical door systems.
12 Annex A
12.1 Mounting variants of IRMA MATRIX sensors
The connection of the IRMA MATRIX sensor to the power supply and the CAN BUS is made
with specially developed connectors which are available in different versions with different
functionalities and properties. For an overview see section 12.1.2 on p. 64.
12.1.1 Mounting sets
The mounting set required for attaching a MATRIX sensor, e.g. DIST500.7-A07.OC is not
part of the delivery and must, therefore, be ordered separately. For an overview for the
selection of the appropriate mounting set see the table on p. 65.

12.3 Connection examples
12.3.1 Installations with sCON-S (standard) for CAN
Fig. 44, p. 69 shows a possible installation in a vehicle with 3 doors. The sensors are
connected to the IRMA CAN BUS with the sCON-S for CAN. The IRMA gateway is located at
the beginning of the CAN BUS.
Fig. 45, p. 70 shows a possible installation of 4 IRMA MATRIX flush mount sensors in a
vehicle with 4 doors. The IRMA gateway is connected in the center of the CAN BUS.
12.3.2 Installations with sCON-F-12
Fig. 46 and Fig. 47 from p. 71 on show two possible installation variants in a vehicle with 3
and one with 4 doors. The DIST500-F MATRIX sensors of the flush mount version are
mounted and connected using sCON-F-12
The voltage supply via CAN is effected after a joint or after 4 IRMA MATRIX sensors.
Characteristics: Fig. 71, p. 71 shows a vehicle with 3 doors; each of the doors is monitored
by one sensor. The IRMA gateway is located at the beginning of the CAN BUS.
In Fig. 47, p.72 4 doors are monitored, the IRMA gateway and the power supply are located
in the center of the CAN BUS.

.
12.3.3 Installation with second power supply in articulated bus
(with sCON-S)
Fig. 48, p. 73 shows an installation where all control signals for the sensors from the onboard computer are realized via a CAN BUS. Connection to the on-board computer is made
with the CAN cable K-M12CAN-S-01-1m (M12 connector (m) and 4 wires, see item 10 on
the left). After the CAN cable has been fed through the articulation, a second power supply
is connected to the CAN BUS (large cable length) via a T-coupler (M12-CAN-CON). In
contrast to the first power supply, the cable K-M12CAN-S-01-1m with an M12 connector
(m) is used here for connection to the T-coupler.
The unused wire ends (construction, white) must be insulated.
18
IRMA MATRIX sensors of the flush mount version (DIST500-F) can only be wired with sCON-F-12.
