USB Interface
The USB interface board is the third element of the Wireless-System.
The interface board is connected to the receiver with a MCS Bus cable, which is about 5 m long.
Longer cables are delivered on request. The advantage is that the interface board can be placed
near to the data acquisition computer in a different room than the experimental laboratory and
the test animal will not be disturbed in excess of the experimental setup and the scientist. The
connection to the data acquisition computer is realized via USB high speed cable, respectively.
Two additional Lemo connectors are available to feed in TTL signals for synchronization of the
Wireless-System with other devices, for example when the test animal is passing a light barrier,
when the animal is feeded or other events, which are manipulating the experiment. The check
box "Digital Input Channel" in "Data Source Layout" must be activated when using the external
digital data, otherwise it is not possible to display the external data on the MC_Rack screen.
Please read chapter “Starting MC_Rack”.
The two LEDs on the back of the interface board indicate the status of the system: The green
LED indicates that power is on. If the green LED flashes, you have to install the newest version
of MC_Rack software, which automatically will update your system with the drivers needed.
When the hardware is successfully installed, the green LED illuminates stable. The blue LED
flashes in slow frequency, when the system is in stand by modus. The blue LED flashes in fast
frequency during data recording.
The interface board does not need an own power supply. It is powered via USB high speed cable
by the data acquisition computer.
