3Connecting IRMA 6 (optionally with angled M12 connectors)
Connect IRMA 6 to power supply
Connect IRMA 6 from component
to the on-board power supply via the wire strands of the power
supply cable K-M12POW-B-oE-04-2m.
Mind the correct connection points (+, - and shield) in the
connection block of the vehicle and See section "Ensuring
power supply", p. 14 for time relay for 30 min overrun power.
Connect IRMA 6 with Ethernet
Connect IRMA 6 from component with the switch via the
M12 system Ethernet cable K-M12CAT5-XX-xm. Via Ethernet
the connection to the OBU and to the service PC is made.
Only possible with service PCs having an Ethernet interface.

Connect IRMA 6 to PC
Connect IRMA 6 with the PC via switch from component with
the M12 system Ethernet cable K-M12CAT5-XX-xm and the
outgoing adapter cable KQ-M12CAT5-RJ45-01-xm for service
purposes (update, configuration).
Only possible with service PCs having an Ethernet interface.
Connect IRMA 6 to door contact (on
demand)
Connect the wire strands of the cable from component either
directly to the door control unit or establish a circuit with the wire
strands via a limit switch (external power supply from vehicle
required).
See cabling diagram for wiring overview of IRMA 6 in the vehicle,

4Configuring IRMA 6
Provide a DHCP server in the LAN. Open DNS. Connect IRMA 6 via the RJ45
service cable with your pc. Enter the device number in the browser bar.
Start configuring IRMA 6. Change the language via “English”.
On the left side you find the navigation:
•for configuring IRMA 6
•updating IRMA 6
•checking logged error messages
•visualizing counting data of IRMA 6
Click on CONFIGURATION to get to the points INSTALLATION and ETHERNET At the point INSTALLATION you set:
•door/function area
•sabotage detection
• status LEDs
•installation parameter

In the section “Door /Function Area” you set the:
•“Function Area Address”
•with the “FA” according to real door / fa number in vehicle
•“Door Address”with the setting value which is, as a rule, identical to the
“Function Area Address” (FA) in an Ethernet installation; and
•“Door Close Delay” with the value of the time determined between the door
closing signal sent by the on-board computer and the actual mechanical
closing of the door.
In the section “Status LEDs” you set “OFF”, as this is the default LED setting of the
sensor.
In the section “Installation Parameter” you set the parameters
for the placement of IRMA 6 according to the measures in the vehicle.
Measure the values for each installation parameter in the vehicle
and enter them. (See graphics below for each installation parameter
in vehicle).

Mounting height Door to sensor distance

Side view
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
Door to sensor distance is the horizontal distance from the sensor to
the (closed!) door.
This parameter marks the boundary between the inside and the outside
of the vehicle in 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.

Vehicle edge offset Rotation angle X
positive value negative value positive angle negative angle
Side view
Vehicle edge offset is the difference in level between the adhesive marker
and the vehicle edge with the door open. The vehicle edge may be below or
above the adhesive marker. Measure the difference in height between
the vehicle edge and the adhesive marking and:
Rotation angle X is the inclination angle of the sensors visual axis (=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. Measure the sensor‘s angle of rotation
(e.g. using a suitable smartphone app) and enter the value measured.
•Set the measured value as positive (> 0 mm)
if the vehicle edge is below the adhesive marker.
•Set the measured value as negative (< 0 mm)
if the vehicle edge is above the adhesive marker.

Left / right wall distance Left / right door clearance
Left/right wall distance is the left-hand/right-hand sensor monitoring
area up to the left/right lateral boundary in the vehicle interior.
Left/right door clearance (passage width) is the horizontal distance
between the sensor and the left/right opened door parallel to the vehicle edge.
Enter 0 mm if there is no opened door in the sensor viewing range.
Set 0 mm if there is no obstacle between the adhesive marker and
the left/right lateral boundary when the door is open.
