    Wireless2100 Headstages The headstage is the first of the three elements of the Wireless2100-System. The headstages are small and lightweight to allow recordings in freely moving animals. Headstages are available with 4, 8, 16 or 32 channels.

  • Page 9: Sampling Rate

    Sampling Rate The Wireless2100-System can sample the maximum of 32 channels with 10 kHz per channel. Depending on the number of selected channels, the sampling rate can be increased even more. If multiple headstages are operated simultaneously with a single receiver, the sampling rate is limited to 2 kHz per channel. For details please see chapter "Technical Specifications"...

  • Page 10: Modules For Additional Functions

    The standard battery (100 mAh) of a headstage permits continuous recording of all channels for more than 2 hours. Empty batteries can be replaced without removing the headstage, and recharged while the experiment can be continued with a second battery. Modules for additional Functions W2100 headstages have a modular design.

  • Page 11: Wireless2100 Receiver

    Wireless2100 Receiver The receiver is the second element of the Wireless2100-System. One receiver of the Wireless2100-System can receive the digitized signals sent from up to four headstages. Four antennas are used for data transmission, one antenna submits control signals to and from the headstage.

  • Page 12: Wireless2100 Interface Board

    The power LED near to the MCS logo on the front panel of the interface board should light up when the Wireless2100-System is "ON", and the device is connected to the power line. If not, please check the power source and cabling.
  • Page 13 The device is switched "OFF" when the toggle switch is switched to the right. If the Wireless2100-System is "ON", and the device is connected to the power line, the power LED on the front panel of the interface board should light up. If not, please check the power source and cabling.
  • Page 14 Analog Channels Eight Analog IN channels are available via 20 pin connector. Please read chapter "Pin Layout" (Analog IN Connector) in the Appendix for more information. The additional analog inputs are intended for recording additional information from external devices, for example data from a microphone Two of the eight analog channels (analog channel 1 and 2) are directly accessible via two Lemo connectors.

  • Page 15: Accessories

    Accessories Default accessories of the Wireless2100-System are the signal generator, the remote control to reactivate the headstage, and the USB charger for the battery. ME/W-Signal Generator The ME/W-System Signal Generator can generate a number of pre-defined sine waves and artificial biological waveforms and feed it into all types of headstages.

    Be careful when using a Virus Scanner. These programs are known to disturb MC_Rack, and even data loss may occur. When using a Wireless2100-System it is recommended to connect a high performance computer with a separate hard disc for program files and data storage. The provided possibility to make long term experiments with a sample rate of up to 40 kHz needs high memory capacity.

  • Page 17: Wireless2100 Hardware Setup

    Connect the interface board with a USB2.0 port of a computer where MC_Rack is already installed. Avoid USB 3.0 ports (USB 3.0 ports are blue). Do not use USB hubs.  Switch on the Wireless2100-System on the interface board. LEDs on the interface board and receiver should light up. ...
  • Page 18 Click "Configuration" in "Source Layout". Enable the check box "Digital Input Channel" if you want to display external TTL signals, fed into the Wireless2100-System via Lemo connectors on the interface board. Deselect the check box, if you do not need additional digital channels.
  • Page 19 „Wireless” Window of Hardware Tab The additional “Wireless” control panel is an extension of the hardware tab, which is only visible if a Wireless2100-System is connected. Click button "Scan" to see all available headstages. Headstages are only available for the system if the battery is connected, if they are within transmitting range, and have not been switched off previously by software command.
  • Page 20 In this tab "Infos" about the connected Wireless2100-System are listed. Click the "Audio" tab of the dialog. On the interface board of the Wireless2100-System you can connect an audio system "Audio OUT" (3.5 mm phone jack) to make the electrical activity audible. This audio output is real-time. Headphones or a speaker can be connected directly to the Audio OUT.

  • Page 24: Experimental Setup

    Experimental Setup First step to set up an experiment with the Wireless2100-System is to implant an electrode into the laboratory animal. The electrode has to be fixed to the skull, for example with dental cement, to guarantee a stable positioning of the electrode in the desired area of the brain. The electrode connector must be available on the skin surface of the animal.
  • Page 25 When external interferences, for example heartbeats, muscle potentials, breathing, disturb the measurements, both, the recording and the reference electrodes measure the same disturbance and the noise signal is removed because only the difference between recording and reference electrode is digitized and transmitted (Common Mode Rejection).

  • Page 26: Troubleshooting

    Please do not use, for example, a mobile phone equipped with blue tooth or a WLAN connection or a microwave in the vicinity of headstage and receiver otherwise it may cause trouble in data transfer.
