FAQ - Frequently Asked Questions


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 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

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 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.

(ref. IT#19394)

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)

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!
