1General
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 (coves1) either flush countersunk or on the surface (sensor versions
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.
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
website: https://www.irisgmbh.de/en/technical-documents/irma-matrix/ (IRMA MATRIX >
Cables).
1A cove is a paneling in the vehicle, here in particular above the door, into which the sensor is to be fitted.

2Important 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.
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
•D5FC-DIST500_Application_2.0.0.5072 Single Count Category-
3521_CE_CF_D0_D1_D4_D5
In all considerations with regard to installation positions and orientation, it is assumed
that the observer is inside the vehicle.
