No Computer Connection / No Recording Possible
You cannot establish a connection to the computer. The USB-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 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-ME-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-ME-System directly to a USB port, not via hub.
