Wireless System Manual

1.2 Welcome to the Wireless Recording System

The innovative wireless recording in vivo system is the all-in one solution for amplifying, recording, and analyzing in vivo data from four, eight, sixteen or thirty-two channels. The bandwidth of the amplifier is 1 Hz to 5 kHz. The sampling rate is software controlled and user defined. With a resolution of 16 bit the accuracy of your data is guaranteed.

The sampling rate is up to 40 kHz when using two electrode channels of the W4-System or four electrode channels of the W8-System and up to 20 kHz when recording on all channels of the W4or W8-System. For the W16-System the sampling rate is 10 kHz when recording on all 16 channels or up to 20 kHz when recording on 4 or 8 channels. Respectively, the sampling rate for the W32System is 5 kHz when using all 32 channels and up to 10 kHz when using 16, 8 or 4 channels only.

The system includes everything you need: Small sized headstage with integrated A/D converter, digitized transmission and a powerful receiver. For controlling the easy to use software package MC_Rack is available. With its excellent signal-to-noise ratio, the W4-, W8-, W16- or W32- Systems are the ideal solution for spikes, LFP, EEC, ECG, and ECoG. Additional inputs to the receiver allow the synchronization of the data with external devices.

The headstages of the systems are extremely small and lightweight and. allow the recording of neuronal activity in freely moving animals. A/D conversion at up to 20 kHz sampling rate in the headstages decrease the bandwidth for data transmission. Thus, it enables a long transmission range and low power consumption at the same time. This makes flexible long time experiments in large environments possible.

With one system it is possible to use up to four headstages in parallel for measuring several animals one by one. With several complete systems you can record from several animals at the same time. Even so the wireless systems can be adapted to different electrode connectors.

The headstage is designed energy efficient. The standard battery (100 mAh) of a headstage permits continuous recording of all channels for more than 2 hours. Recharging is then realized via USB. When doing experiments with animals insensitive to weight, MCS also offers larger batteries, which provide longer recordings. For the W4-System a smaller 30 mAh battery (1.5 g) is available. Please contact Multi Channel System MCS GmbH for more information on battery options.

The battery can be fixed on the top side of the headstage or can be stored in a special backpack adapted to the size of the animal.

Wireless System Manual

The connector of the headstage is connected to the electrode which is implanted into the brain of the laboratory animal. The external connector of the implanted electrode is fixed, for example with dental cement.

For maximum flexibility, MCS offers headstages with connections to all probes on request.

The headstage records analog signals from the electrodes. The integrated A/D converter converts the analog signals into digital signals, which are sent to the receiver via radio communication in the 2.4 GHz frequency band. Thus, it enables a long transmission range and low power consumption at the same time. This makes flexible long time experiments in large environments possible.

The headstage and the receiver should be placed near to each other in the experimental setup. They may have a distance to each other of about 5 m without data loss.

First Tests of the Headstage with a ME/W-Signal Generator

For initial testing the Wireless-System you do not have to operate with a laboratory animal, but you can use a signal generator.

The ME/W-System Signal Generator is a convenient tool for the user. As a variable substitute for laboratory animals you can use the ME/W-SG as you would set up a research experiment.

That means you can test your Wireless-System and data acquisition settings without using valuable biological samples. It has the advantage that you do not need an animal, you reduce the number of animal experiments and save laboratory equipment. Please connect the headstage to the signal generator as shown on the picture. Please read the data sheet in the Appendix for operating the ME/W-Signal Generator device.

Charging Set

The charging set for the storage battery works via any USB connector. To recharge the battery, please connect the charging set to an USB port of the computer and plug the battery into the back of the charger.

The red LED on top indicates that the device is on. The yellow LED indicates that the storage battery is being recharged. After approximately one hour the green LED indicates the end of process.

Hardware

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.

Wireless System Manual

3.3 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.

In "Edit" menu choose "Data Source Setup". The following “Channel Layout” dialog appears.

Select USB-MEA in the left drop down menu of "Data Source". The W8-System "MCS WPA8 (S/N xxxx)" will automatically appear in the right drop down menu. In "Source Layout" the check box “1 dimensional” is predefined and the "Number of Channel" in total is “8”.

Enable the check box "Digital Input Channel" if you want to display external TTL signals, feeded into the W8-System via Lemo connectors on receiver and interface board. Deselect the check box, if you do not need additional digital channels.

Add the W8-System and a display to the virtual rack. Click "Hardware" tab.

Wireless System Manual

There is an additional window in “Hardware” tab for the W8-System called “Wireless”, and the MC_Rack display shows an additional status line

The “Sampling Frequency” of the system depends on the number of channels which are in use. When recording with all eight available channels the sampling rate is limited to 20 kHz. Recording with one to four channels only is possible with a sampling frequency of up to 40 kHz.

Click the “Sampling Frequency” drop down menu and select the desired sampling rate.

Click “Amplification Gain” button “Enter”.

The “Enter Amplifier Gain” dialog appears. The fixed amplifier gain of 100 for the wireless headstage is displayed in the list. Please type 100 into the window above.

Software

Wireless Window

The additional window “Wireless” is for software control of the wireless system. In “Select Headstage” you can select one of the four headstages A, B, C, and D if more than one headstage is connected to the system. After pressing the button “Scan” the receiver scans which headstages are available. Then the user is able to select the desired headstage.

The appropriate channels of the selected headstage are chosen by clicking on the channel number. In the Wireless Window the selected channels appear pressed in as shown on the screenshot, Channel No 05, 06, 07, and 08.

To minimize energy consumption, you can switch off the headstage by clicking the button “Switch Off”. The headstage changes from “Stand By” modus into the “Switch off” modus. From “Switch off” modus it is not possible to switch a headstage back on via software control.

The blue LED mounted on the headstage of the W8-System indicates the recording phases. It can be switched into three modes via radio button. Select “Off” if the laboratory animal is disturbed by the light. Switching off the LED will save a little bit of energy. Select “Blink” and the LED flashes during recording. Select “On” and the LED will be on permanently. This feature can be used, for example for camera tracking.

The W32-headstage is equipped with two LEDs, the blue one and an additional red one.

The user has the same options to set the red LED. Both LEDs together improve the camera tracking, because with two LEDs it is possible to track the orientation of the headstage.

Choose a “RF Output Power” value from the drop down menu. The smaller the value, for example –6 dB, the longer the storage battery will support the recording, but the smaller the distance between animal and receiver.

Wireless System Manual

Strategies for Saving Energy

The standard recording time with a fully charged battery is 120 minutes at 20 kHz and 0 dB output power in a range of up to 5 m between headstage and receiver. Please read chapter "Power Consumption" in the Appendix.

To prolong the recording time until the battery has to be recharged on the one hand you can decrease the sampling frequency, on the other hand you can decrease the RF output power.

For example, when recording with 500 Hz sampling frequency you save 100 mA per hour and the energy of the storage battery lasts for a recording time of eight hours. This may be useful for experiments in epilepsy research.

For example, when recording with –18 dB at 20 kHz sampling frequency you save approximately 50 mA per hour, that means the recording time is 30 minutes longer compared to the time when recording with 0 dB. However, the transmission power will decrease respectively.

Starting the W8-System again after switching off via software

To switch the headstage back on after pressing the button "Switch Off", the user has two possibilities: Use the infrared flasher and illuminate the receiver LEDs next to the battery connector. Then press the button "Scan" in "Wireless Window" to reconnect to the headstage.

The second possibility is to unplug the battery from the headstage manually and to reconnect headstage and battery again.

Add a display to your rack.

The number of displayed channels depends on the number of selected channels in “Wireless” of “Hardware” tab.

For detailed information about the use of MC_Rack, please read the MC_Rack manual.

Software

Software Settings when Using different Types of Headstages with one Wireless-System

May be you will use your wireless system in different experimental setups, that is for example, first with an eight channel headstage and then with a four channel headstage. In this case you have to adapt the wireless system to the variable hardware requirements via MC_Rack software. MC_Rack needs specified driver units for each hardware component, which must be loaded when changing the type of the headstage.

The following example describes how to change a W8-System to a W4-System. The W8-System is already connected to the data acquisition computer and installed.

Open a new empty MC_Rack file and select “Data Source Setup”. The system with eight channels will be found and displayed.

Click the button “Change Wireless Device”.

Select the W4-System from the drop down menu “Wireless Device Type” and confirm with “OK”.

Wireless System Manual

The installation lasts a few seconds.

Please wait until the new driver has been loaded and the headstage is internally switched.

If you install the W4 headstage for the first time, a hardware installation assistant will appear. Please follow the installation instructions. If the drivers for the W4-System have been installed before, ignore this step and click the “Refresh” button in the “Data Source Setup” dialog.

Software

After the hardware installation process, please click the “Refresh” button in the “Data Source Setup” dialog to update hardware and software.

The W4-System will now be available in the “Data Source Setup” dialog. Select the desired headstage device from the drop down menu and start working as described above.

5 Operating a Wireless System

5.1 Experimental Setup

First step to set up an experiment with the wireless system is to implant an electrode into the laboratory animal. The electrode has to be fixed, for example with cement used in dental technic, to guarantee a tight position of the electrode in the desired area of the brain. The electrode connector must be available on the skin surface of the animal. Implant a ground option additionally, if necessary.

Use of the Reference and Ground Electrodes

For in vivo experiments it is necessary to provide a good option for grounding (GND) and a well placed reference (REF) electrode. Therefore all headstages of the Wireless-System are equipped with electrical isolated pins for a ground and a reference electrode.

Important: For good signal quality you should use dedicated reference and ground electrodes!

The reference electrode is used to measure the relative potential differences in relation to the recording electrodes. It should be out of a similar or the same material as the recording electrodes and it should be of comparable size. The reference is ideally placed near the recording electrodes, but not in active tissue.

The signals from all electrodes are amplified and then each signal from the recording electrodes is compared to the signal from the reference electrode. The difference is measured by the analog to digital converter (ADC) and digitized.

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).

Wireless System Manual

To make sure that the animal and the headstage are set to the same electrical potential, a grounding connection is also necessary. A good ground option is usually a large conductor, such as a screw or a silver wire implanted under the skin of the animal.

Experimental Setup

Connect the receiver to the USB interface, and the USB interface to the data acquisition computer. Switch on the computer and start the MC_Rack program.

Make sure that the storage battery of the headstage is charged and plugged in properly. The battery can be fixed on top of the headstage with a magnet or it can be stored in a special backpack on the back of the animal.

Connect the wireless headstage to the electrode connector on the skin surface of the test animal.

Connect the receiver via MCS Bus cable to the interface board and the USB cable to the data acquisition computer. The cable between receiver and interface board is 5 m, longer cables are available on request. The USB cable between USB interface board and computer is 2 m. The receiver and the interface board are powered by the computer.

The software MC_Rack is for data acquisition and data analyzing. Please read the MC_Rack manual for detailed information.

Operating a Wireless System

5.2 Operating Modes

Recording Mode

Set up all components of the Wireless-System. Start MC_Rack and add the Wireless-System as data source. Please read chapter “Starting MC_Rack”. Define the amplifiers gain of 100 and select the sampling frequency in the “Hardware” tab.

Make sure the storage battery is completely charged. Connect the battery to the white connector on the headstage.

In the “Wireless” window of the MC_Rack “Hardware” tab, press the button “Scan” to find the headstages available. After that the user is able to select the desired headstage (A, B, C, D) when using more than one headstage. All eight recording channels are selected by default. Deselect the channels you do not need.

The Wireless-System is in recording mode now. You can start recording by pressing the “Start” button in MC_Rack. The storage battery allows recording of approximately two hours.

After the experiment stop the recording by pressing the “Stop” button.

The “Recording Mode” is indicated by a high frequent flashing of the blue LED on the headstage.

Stand By Mode

To save energy the Wireless-System changes from “Recording Mode” into “Stand By Mode” immediately after stopping the recording. The “Stand By Mode” allows starting the recording again at any time. In this mode the storage battery lasts for up to eighty days depending on the recording time before.

The “Stand By Mode” is indicated by a very weak and slow flashing of the blue LED on the headstage.

Switched Off Mode

To save more energy than in “Stand by Mode” you can switch the headstage off.

In the “Wireless” window of the MC_Rack “Hardware” tab, please press the button “Switch Off” to switch off the selected headstage.

In this mode the battery lasts for up to 130 days depending on the recording time before.

Switching the headstage on from this mode is not possible via software control. To do so the user has two possibilities: Use the infrared flasher and illuminate the receiver LEDs next to the connector for the battery. The flasher and the headstage should have a distance of about 5 to 10 cm. The second possibility is to unplug the battery from the headstage manually and to reconnect headstage and battery again.

Then press the button "Scan" in "Wireless Window" to reconnect to the headstage.

Wireless System Manual

Operating up to four Headstages rotatory with one Wireless-System

It is possible to operate up to four different headstages connected to one Wireless-System in a rotatory system. The headstages are discriminated via frequency band for the radio communication. Each headstage is labeled with a letter (A, B, C, D). Please see the bill of delivery for the assignment of the headstage and the frequency band. (When using one single headstage only, the headstage is automatically A without a label.)

After pressing the button “Scan” the receiver scans which headstages are available. Then the user is able to select the desired headstage.

After recording from the first headstage, you can choose the second headstage in the “Wireless” window, the third and the fourth.

Operating up to four Wireless-Systems in parallel with one Computer

It is also possible to operate up to four different complete Wireless-Systems with one data acquisition computer. This way, you can experiment with up to four laboratory animals contemporaneous. The headstages are discriminated via frequency band for the radio communication again. Headstages and related receivers are labeled for differentiation.

Set up the Wireless-Systems and connect them to the data acquisition computer. Start as many instances of MC_Rack software as you need. In “Data Source Setup” assign the Wireless-Systems via serial number to the instances of MC_Rack.

6 Troubleshooting

6.1 Troubleshooting

Most problems occur seldom and only under specific circumstances. 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.

or D

to assign the headstage to A, B, C or D, which is indicated by the green color

in the "Found" button

To change your selection you can simply choose a new assignment. The information whether the headstage is A or C for example, will be permanently stored on the headstage and can be changed at any time. Power the next headstage and assign it to another letter or to another system with a different "Frequency ID" the same way as described above.

In the screenshot above, different headstages are assigned to the four Wireless-Systems connected to the data acquisition computer, defined by the "Frequency ID" and the labels "A", “B”, “C” and "D".

Appendix

Click the button "Distribute default" to keep the "Frequency ID" in a line, ID 1 to ID 4.

If you try to give the same frequency ID to different systems you get an error message. "Frequency ID each ID must be different!". Please choose another ID.

When using a second data acquisition computer nearby to record from an additional wireless systems, please make sure that the frequency IDs differ from each other. Otherwise the systems will interfere.

To change the high pass filter, press the button "Change". The "Change High Pass" dialog will open. Click the radio button of the desired frequency 0.1 Hz or 1 Hz. This information will be permanently stored on the headstage.

Wireless System Manual

To Do Checklist before start working with a Wireless-System in a new configuration:

1. Start the Wireless-System Config program. The main window opens.

2. When connecting more than one Wireless-System to the data acquisition computer the main window appears twice or more. Please make sure that each system on one data acquisition computer has a different frequency ID. Your Wireless-System(s) is / are now detected by the Wireless-System Config tool. The serial number of your receiver(s) is / are displayed in "Found Wireless-System S/N".

3. Choose your W-Type from the drop down menu, which possibly is already chosen.

4. Now please connect the first headstage to a battery. The headstage switches on, that means the blue light flickers

Important: Configure only one headstage at a time!

6. Press "Select W4" to define the headstage as "A", "B", "C"; or "D" . This step determines the frequency band of this particular headstage.

7. The established connection is indicated by the green color of the "Found" button.

8. Disconnect the first headstage, which is configured now. Connect the next headstage and configure it either to the same Wireless-System (receiver) with the same frequency ID, but to another frequency A, B, c or D. Or you connect the headstage to another Wireless-Systems and perform the same procedure as described above.

10-pin single row connector for W4 and W8 (single row) and MPA8I headstages.

40-pin Omnetic connector for W32 headstage and for μPA32 preamplifier.

20-pin Omnetic connector for W8 and W16 headstages and for μPA16 preamplifier.

Connect the W8-headstage (single row connector) of the Wireless-System to the 10-pin single row precision connector. The W4-headstage needs an adapter to fit into the single row connector. Connect the μPA32 of the ME-System and the W32 headstage of the Wireless-System to the 40-pin Omnetic connector. Connect the μPA16 of the ME-System and the W16 and the W8 (with Omnetic connector) of the WirelessSystem to the 20-pin Omnetic connector.

Connect the wireless headstages W8 and W16 according to the guide posts as shown on the photos beside. The orientation of the W32 does not matter.

Additionally it is possible to connect the MPA8I-System to the ME/W-SG. Please insert the MPA8I headstage together with the adapter in correct orientation into the 10-pin single row connector as shown on the photo below. The MPA8I headstage is equipped with an 11-pin connector, that is why one of the pins is not connected. The bottom of the MPA8I headstage (black side) must show to the bottom of the signal generator. The free pin of the 11-pin connector must be on the right side.

MPA8I headstage connected to the ME/W-SG

Please connect the MPA8I headstage with the provided 10-pin double row adapter in correct orientation to the ME/W-SG.

W4 headstage connected to the ME/W-SG

Please connect the W4 headstage with the provided 6-pin double row adapter in correct orientation to the ME/W-SG.

The ME/W-Signal Generator is a very convenient tool for users of the Wireless-System and / or for users of ME-Systems. Use the ME/W-SG instead of setting up a complete experiment for training, controlling, and troubleshooting purposes.
