3.2 Receiver
The receiver is the second element of the Wireless-System.
The receiver of the Wireless-System receives the digitized signals sent from the headstage
in a distance of about 5 m. The device is equipped with four antenna to prevent data loss.
Two Lemo connectors on the front panel, labeled with D0 and D1 are available to feed in TTL
signals for synchronization of the Wireless-System with other devices. For example, when passing
a light barrier, feeding the animal or other events which manipulate 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 receiver indicate the status of the system: The green LED
indicates that power is on, the system is ready for recording. The blue LED flashes in a slow
frequency, when the system is in stand by modus. The blue LED flashes in a fast frequency
during data recording.
The receiver and the interface board respectively do not need an own power supply. They
are powered by the USB high speed cable connected to the data acquisition computer.
