5 Troubleshooting
5.1 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.
5.2 No Computer Connection / No Recording Possible
You cannot establish a connection to the computer. The USB-MEA256-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. You get an error message when starting
the recording in MC_Rack after a successful computer connection.
Possible causes:
? The power LED is not lightning. 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 USB-MEA256-System is connected via 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 USB-MEA256-System directly to a USB port, not via hub.
