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 8.1.2 "PC connection via Ethernet interface", p. 44.
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:

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).
"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:

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:
Rev. 1.6 2018-09

• 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).
