1GENERAL INFORMATION
1.1 Functionality and Features of the CM_CAN_Combo
Figure 1-1: Capture_Module_CAN_Combo
The Technica Engineering Capture Module CAN Combo is used to capture the traffic
from the conventional CAN busses, as well as CAN-FD, FlexRay and RS-232 can be
captured without interfering the original networks.
Several devices can be used on the same setup, whenever more interfaces are needed,
and when other IVN technologies are present, the in-built-synchronization using
802.1AS allows for simultaneous use with the other “IVN2Eth Capture Modules”.

By the 100BASE-T1 port (PIN 9 and 10) in this connector, you get access to the
webserver by the default IP address (192.168.0.49 if not changed). To configure the IP
address, please see CHAPTER 4.3.2.
2.1.2 RJ45 Ethernet connector
There is one RJ45 Standard Ethernet connector on the front side for Gigabit Ethernet.
Here you can log and configure the device. And this port is for time synchronization
between different CaptureModules from Technica. For details please see CHAPTER
4.5.4.
2.1.3 Black MQS Connector Backside (26 pins, 2 rows)
Figure 2-3: MQS Connector backside
The pins marked with (P) or (M) are used for the CAN ports.
Pins marked with (G) are Ground Pins.
The user has to connect the (P) pin to the (P) pin of the periphery device.
The user has to connect the (M) pin to the (M) pin of the periphery device.
Note: For each CAN (-FD)-port there are 4 Pins available: 2 plus and 2 minus ports.
Both Plus and both minus ports are shortcut.
Advantage for using only 2 pins: there is no need to for a plugged CM_CAN_Combo
while using the testsetup.
Disadvantage for using 2 pins: The stub to the CAN-bus is as long as your cable.

CM CAN Combo User Manual

Advantage 4 pins: The stub is only 5mm (internal in the device) and no termination
needed.
Disadvantage: the device or a bridge connector has to be plugged.
Note: there is no internal termination in the CM_CAN_Combo for the CAN-Ports

2.1.5 Micro HDMI connector
This is an interface for programming and debugging (only for development.)
2.2 Other Interfaces
2.2.1 Rotary switch
The following IPs will be set as default for the CM_CAN_Combo.
You get access to the Webserver only by the configured configuration port. Out of the
box the 1000BASE-T-Port is set as the configuration port.
•Rotary switch on 0 -> IP: 10.104.3.64
•Rotary switch on 1 -> IP: 10.104.3.65
•...
•Rotary switch on D -> IP: 10.104.3.77
•Rotary switch on E -> IP: 10.104.3.78
•Rotary switch on F -> IP: 10.104.3.79 / Reset
2.2.1.1 Rotary switch in status 0 to D
The IP addresses are not configurable by software or by any user interface and can
only be changed by using the rotary switch. It is overtaken after 500ms by a software
reset. The current IP address is shown on the System Information tab. Access to the
CM_CAN_Combo is given through the defined configuration port: 1000BASE-T-port or
100BASE-T1 Ports on the Frontside (Host).
The set IP address is part of the TECMP header if TECMP is activated.
2.2.1.2 Rotary switch in status E
The IP address 10.104.3.78 is the default IP address. In this Rotary switch status the
IP address is configurable on the System Information tab. The configured IP address
is valid even there is a power reset, or the Rotary switch has been changed and is
switched back to “E”. The valid IP address in this Rotary switch position is part of the
TECMP header if TECMP is activated.
2.2.1.3 Rotary switch in status F
The IP address 10.104.3.79 is the default IP address. It is not configurable. The IP
address is not overtaken after changing the rotary switch from any position to position
“F”. There will be no software reset. A power reset is needed. But if there is a power
reset in this Rotary switch status, the CM_CAN_Combo will be reset to out of the box
status. Complete configuration will be lost and set to default.

CM CAN Combo User Manual

To get access again by another IP address, once a power reset is needed in another
Rotary switch position than “F”.
2.2.2 Status LEDs
The CM_CAN_Combo has several status LEDs at the front side of the case.
Figure 2-5: LED allotment on front of the device
Right side:
LED F:
The “FPGA” LED toggles (approx. 2 sec) during normal operation. If it is not blinking
or blinking faster, FPGA is damaged and must be repaired
LED H:
The “Host” LED can toggle at two different speeds:
oSlow toggle (approx. 1 sec) during normal operation
oFast toggle (approx. 0.2 sec) if device is in Bootloader mode
Left side:
These LEDs show the status of the connected devices to the 100BASE-T1-Port
LED H:
Connection to the Host/Microprocessor (1)
LED F:
Connection to the FPGA (2)
LED “on” (static) indicates LinkUp
LED blinking means communication on 100BASE-T1 Port

3ACCESS BY WEBSERVER
You can get access to the Webserver by connecting the device via the 1000BASE-T-
Port (RJ-45) to your PC. Here the IP address of the device is dependent on the status
of the rotary switch (see CHAPTER 2.2.1)
Or you get access to the Webserver by the 100BASE-T1 Port to the Microcontroller and
the default IP address 192.168.0.49. The default configuration of this port is as
100BASE-T1-slave.
1. Please go to the networkadapter settings and adjust the IP in the same range of
your CM_CAN_Combo, dependent on which port you are connected to.
2. Enter the IP Address in your standard web browser. For more information about the
IP addresses see CHAPTER 2.2.1 and CHAPTER 4.3.
Note: Chrome or Firefox are recommended.
