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
1
) 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

A cove is a paneling in the vehicle, here in particular above the door, into which the sensor is to be fitted.
