- How do I find the network name of my device as well as its MAC address?
Network device designation and MAC address
Registration of the devices on the network (device designation and MAC address)
Find out how to determine the network name of the device as well as the MAC address of TCP/IP devices.
1. Determining the network name of the device
The devices are registered with the device designation per nameplate on the network.
2. Determining the MAC address of a TCP/IP device
To determine the MAC address, a ping must first be sent to the IP address of the measurement device, then use the command "arp –a".
The IP address can be determined by using the program IF Config for devices with the serial number 12xxx with 400kHz total sampling rate and serial number 13xxxx and 14xxxx. For all other devices, use the program TCP/IP Config. The accompanying notes will work for both programs.
Start the program imc DEVICES IF-Config, it is located in the Start folder of imc DEVICES.
Find your measuring device in the network, then go to the "LAN configuration". The current IP address can be read here.
Go to "Start," then "Run" and in Windows NT, 2000, XP and Vista enter "cmd" and in Windows 95, 98, Millennium, "command".
In the DOS shell (MS-DOS input form), manually enter "ping" followed by the IP address (e.g., ping 10.0.10.11) and press "Enter". Next, type "arp –a" and again press "Enter". Now the MAC address is determined. It is listed after the IP address in the "Physical. address" that you used to "ping".
- How can I tell if the UPS in my measurement device is defective?
Turn on the imc measurement device and simulate a power failure.
If the function of the UPS shuts down after the set UPS time +5 seconds, then the UPS is functioning.
f the device shuts down before this amount of time, then either the UPS battery has not had enough time to charge or the UPS is defective.
To charge the device, plug the device into a power supply for six hours in the ON position. Then, the power failure can be re-simulated.
- In imc Online FAMOS, how can I create a “fast” GPS channel?
To create a "fast" GPS channel, simply use an appropriate, quick reference channel and use this with the "CreateVChannelInt". To use this feature, the control constructs must be enabled in Online FAMOS.
Geben sie folgende Zeilen in Online FAMOS mit Steuerkonstrukten ein:
VC_Satellites = CreateVChannelInt (Channel_001, pv.GPS.satellites)
VC_Longitude = CreateVChannelInt (Channel_001, pv.GPS.longitude)
VC_Latitude = CreateVChannelInt (Channel_001, pv.GPS.latitude)
VC_Speed = CreateVChannelInt (Channel_001, pv.GPS.speed)
The Channel_001 is the quick reference channel, thus providing the "time track" for the virtual channel "VC_Satellites". For each value the GPS Mouse delivers, there is a corresponding process vector variable.
- Why does the importing of TEDS information not work with imc CRONOSflex ISO2-8?
At this time importing of TEDS information for this module is only supported without "preparation":
turn on device -> connect with software -> activate all channels -> import TEDS
- Why can't I find my imc CANSAS module on the CAN-bus?
Module not found
I can't find my imc CANSAS module on the CAN-bus
1.) Is the CAN-bus is terminated correctly?
Both ends must be terminated with a terminator (124 ohms according to CiA). (See Figure 1) If the module or instrument has only a CAN-bus connection, e.g., imc CRONOS-PL, then the termination should be made via a Y-cable and a terminator.
2.) Is each module set to the same transfer speed/baud rate?
All CAN-bus participants/modules being operated at a given node must be set to the same baud rate or else communication between the participants in the bus is not possible.
3.) Does the set baud rate and cable cross-section size match the cable length?
The transfer rate on the bus is dependent on the cable length, the cable cross-section and the number of nodes. The greater the cable length, the lower the possible transmission rate will be and a larger cable cross-section must be selected. (see Figure 2)
For more information, see the current imc CANSAS Manual
- Why is my NetBEUI measurement system not displayed in the network search with MS Windows XP?
In contrast to other MS Windows versions, under MS Windows XP you must follow different instructions for installation of the NetBEUI protocol. If you already have NetBEUI on your PC, uninstall it before the new installation process and restart the PC.
1. Insert the Windows XP CD-ROM and go to the folder Valueadd\MSFT \Net\NetBEUI.
2. Copy Nbf.sys to %SYSTEMROOT%\System32\Drivers.
3. Copy Netnbf.inf to the %SYSTEMROOT%\Inf.
4. Click on Start, then Settings, then Control Panel, then double-click on Network and Dial-up connections.
5. Right-click on the entry for "Local Area Connection" and select "Properties" from the context menu which appears.
6. On the index card "General", click on the button "Install...".
7. In the dialog which then appears, select "Protocol" and then "Add...".
8. It should now be possible to select the NetBEUI protocol in the list. Select NetBEUI and click on OK.
9. Restart the computer.
Note: Administrator rights for your PC are required.
- Which version of imc CANSAS supports Kvaser Leaf SemiPro HS?
The interface is supported by the imc CANSAS Version 1.9 R4.
- My measurement data are incomplete. How can I repair this?
Among other things, incomplete measurement data occur if the UPS in the device is defective and, is therefor, not allowing the device to shut down correctly.
To repair the incomplete measurement data, follow these steps: First, download the following file:
Then, simply copy Repair.exe and dirrepair.bat into the folder with the defective files (Make a Back-up first!) and execute dirrepair.bat. After this, you should now have access to the defective data.
Unfortunately, this doesn’t work in all cases. Always make sure that you make a back-up copy of your data. If this solution hasn’t worked, please contact the imc Hotline.
- Why doesn't the shunt calibration in my CANSAS module function correctly?
CANSAS and shunt calibration
The shunt calibration in my CANSAS module doesn't function correctly.
When performing a shunt calibration, channels that are set for half or quarter bridge measurement, cannot be open. Otherwise, during shunt calibration, incorrect readings will occur.
We therefore recommend to not set wired channels on the voltage measurement with maximum range or to not transmit over these channels (change CANSAS software to "without CAN message")
- How do I install my Kvaser interface (supplied by imc) so I can use it with imc CANSAS?
Insert the supplied driver CD and follow the installation instructions. Alternatively, you can also download the driver at the following link:
Only after the driver is installed should you connect the interface to the PC.
After the connection to the PC, the Windows Wizard will appear and display “Found New Hardware”. Since you have already installed all the necessary driver data, you need only click through the menu. Windows detects and connects the driver data in this step automatically.
In the last step, the interface in the imc CANSAS software can be found under Extras -> Interface Activate. Then, click on “board”:
KVASER GmbH ???(USB/PCI/PXI/ExpressCard/PCMCIA)
Then, check the box next to “(re)activate interface”
- Why does the Diskstart not work, as soon as I measure with a digital imc CRONOSflex module?
The Diskstart with digital CRFX modules(See manual of imc CRONOS system family) is not supported at this time. The Diskstart with those modules is supported with imc software version as of 2014-03-19.
- I installed the driver for the imc CAN/USB adapter, but my interface is not detected! Why?
Up to the end of 2014, the imc CAN/USB adapter was supplied. At the end of the imc CANSAS installation, the dialog refers to the driver of this interface.
How you set up the Kvaser Leaf SemiPro HS interface for the imc CANSAS is described in the FAQ below.
- Why am I receiving implausible measurement values from my test system?
Implausible measurement values
I am receiving implausible measurement values from my test system.
Often times the problem can be traced to inadequate grounding of the device or the shielding on the signal wires. Through potential differences between the modules, and other connected devices, such as a laptop, BUSDAQ, etc., there can be compensation currents that can cause disturbances, and in the worst case, could destroy the module.
1. Grounding of the CANSAS module
Because it is anodized, the aluminum case itself is, generally, poorly conductive. Therefore, the locking bolts of the DSUB connector sockets should be used for grounding the device.
2. Shielding on the signal wires
Basically, to stay within the limits with respect to EMC and EMI, the use of shielded and grounded cables are necessary. In many cases, the use of a cost-effective, multi-conductor and simple shielded cable (also for multiple channels) is sufficient. (see Figure 1)
However, it may be necessary in other cases, to use double shielded cable. That is, common grounded (CHASSIS) and jacketed, within which individual (also more) coaxial cables are placed.
In particular, to avoid increased interference (noise), this process may be necessary if under the following conditions:
- "Higher" internal resistance of the signal source (> 100 Ohms)
- Signal sources not grounded (isolated or high impedance over CHASSIS and/or ground reference of the supply)
(see Figure 2)
3. Grounding from the CAN-Bus
Long CAN bus wires between the grounded module and the CAN data logger (device) can cause compensation currents on the bus. Therefore the CAN-bus shielding should only be opened at one end.
For more information, see the CANSAS Manual Version 1.6, section 5.4
- Why does my imc CRONOSflex ISO2-16-2T not measure?
At the moment the Module imc CRONOSflex ISO2-16-2T is only supported with the following software versions:
- imc DEVICES 2.8 R3 SP9 (13.12.2013) + AddOn 04.02.2014
- imc DEVICES 2.8 R5 SP1 (13.11.2013)
- I ordered an imc USB Interface and I received a Kvaser Leaf SemiPro HS Interface for my imc CANSAS. Is this a mistake?
No. At the end of 2014, the imc CAN/USB interface was replaced by the Kvaser Leaf SemiPro HS Interface, which is currently the best on the market.
- How do I find out if a device has a CAN1 or CAN2 interface?
- Connect your measurement device to the PC
- Open imc DEVICES and connect to the device
- Now go to: Devices -> Properties...
- After saving, open the window Device Configuration
- In the table, find the entry MFBus-Module
- Click on the "+" on the left side of the column, a new row("Type") will become visible
- On the right side of the row, you can now read the type of fieldbus interface
- If it has the label CAN (MCAN), then it is always a CAN 1 Interface
- If it has the label CAN (MBUS_X), then it is always a CAN 2 Interface
- What should I consider when using Li-Ion batteries?
Because of the unavoidable self-discharge of Li-Ion batteries (smart batteries), it is recommended that the device be reconnected to a power supply no later than after 3 months of operation to fully charge the internal Li-Ion batteries.
- The batteries recharge automatic when the device is connected to a power supply.
- Charge time per Li-Ion battery: up to 3 hours
- The storage of discharged smart batteries is not recommended and can possibly render them (the battery pack) unusable!
- Capacity per Li-Ion battery:
- 69 Wh (small, CRFX/HANDLE-LI-IO-L)
- 95 Wh (large, CRC/B-Li-IO-1 and -2)
* pertains to imc CRONOScompact (CRC/B-Li-IO-1 und -2) and imc CRONOSflex (Power Handle: CRFX/HANDLE-LI-IO-L)

- Can my measurement device be retrofitted with a SSD hard disk?
SSD hard disk
Can my measurement device be retrofitted with a SSD hard disk?
Yes it can!
An internal 128 GB SSD hard disk (SATA) is available for imc CRONOSflex (CRFX-400,CRFX-2000) and for imc CRONOScompact.
An SSD hard disk offers the significant advantage over IDE disks by having improved vibration resistance.
An additional advantage over the IDE is also an increased temperature range. The IDE functions between 0°C to +50°C. The SSD hard disk is specified for a temperature range between 10°C to +70°C.
Notice: Not every comercially available SSD hard disk is compatible with imc devices. The SSD hard disks that we offer were specifically chosen and tested by us.
For additional questions, please contact your local imc partner, or contact us via the Hotline.
- What is there to consider about flash disks?
Flash disks: What is there to consider?
Which brand of flash disk do we recommend? What is there to consider?
In principle, any commercially available PCMCIA flash disk or CF memory card can be used. However, the cards on the market differ in writing/reading rates, timing and power consumption. In the "worst-case" this could lead to data loss.
Please take note of our white paper "How to use removable media".
Caution: We recommend using factory tested flash disks, since data overflow means loss of test data!
