7 Troubleshooting
The following hints are provided to solve special problems that have been reported by users. Most problems
occur seldom and only under specific circumstances. Please check the mentioned possible causes carefully
when you have any trouble with the product. In most cases, it is only a minor problem that can be easily
avoided or solved.
If the problem persists, please contact your local retailer. The highly qualified staff will be glad to help you.
Please inform your local retailer as well, if other problems that are not mentioned in this documentation
occur, even if you have solved the problem on your own. This helps other users, and it helps MCS to
optimize the instrument and the documentation.
Please pay attention to the safety and service information in the separate manuals of the related products
and in the software help. Multi Channel Systems has put all effort into making the product fully stable and
reliable, but like all high-performance products, it has to be handled with care.
7.1 No Computer Connection / No Recording Possible
You cannot establish a connection to the computer. The Portable ME-System channel layout is not available
in MC_Rack. When loading a previously saved virtual rack file, you will get an error message and the
simulator will be started automatically.
Or you get an error message when starting the recording in MC_Rack after a successful computer
connection.
Possible causes:
? The power LED is not lighting. The supply power is not connected or there is a technical problem with
the instrument.
Check the power source and the cable connections. If this does not solve the problem, contact your local
retailer for support.
? The power LED is lighting. The USB port might not support USB 2.0 or might not be working.
Check the USB port. Only full speed USB 2.0 ports can be used. Try another USB 2.0 port.
? You can establish a connection, but get an error message when starting the recording in MC_Rack. The
bandwidth of the USB port is not sufficient for recording. This can be the case if the Portable ME-System is
connected via a USB hub, and a second device that sends or receives continuous data streams, for example
a web cam or USB speakers, is connected to the same USB port.
Connect the Portable ME-System directly to a USB port, not via a hub.
