Welcome to the Wireless2100-System
The Wireless2100 in vivo recording system is the all-in one solution for amplifying, recording, and
analyzing in vivo data from four, eight, sixteen or thirty-two channels. The system consists of small
sized headstages with integrated A/D converter, a receiver, and an interface board with connectors
for additional analog and digital data in and outputs. For data acquisition and analysis, the easy to
use software package MC_Rack is included.
Headstages are available with 4, 8, 16 or 32 channels. Each Wireless2100-System can operate with any
type of headstage. With its excellent signal-to-noise ratio, adjustable sampling rate and wide frequency
range, the W2100-Systems are a versatile solution for spikes, LFP, EEG, ECG, and ECoG. The headstage
records analog signals from the electrodes. The signals are amplified and digitized directly on the
headstage, and transmitted to the receiver via radio communication in the 2.4 GHz frequency band.
Digital data transmission guarantees a long effective range without loss in data quality. Additional in-
and outputs on the interface board allow the synchronization of the data with external devices, and the
simultaneous recording of additional analog data, for example from a microphone.
As advanced option, the Wireless2100 system allows the possibility to record from up to four
headstages with one receiver simultaneously (at a reduced sampling rate). You can connect two
receivers to one interface board, thereby building a system for up to eight headstages. It is possible to
position four receivers in one room, thereby having a four-fold system with a total of sixteen headstages,
from which you can record in parallel.
Furthermore, the modular design of the Wireless2100 headstages allows the customization with
additional functions based on customer requests. At the moment, only the basic recording option is
available. Optional modules for electrical and optical stimulation, as well as motion tracking are under
development.

System Components
The Wireless 2100-System consists of three main components: the headstage with battery, the receiver,
and the interface board, which is connected to the computer. Accessories are the signal generator, the
remote control to reactivate the headstage, and the USB-charger for the battery. The components are
presented in detail below.
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. Each Wireless2100 receiver and interface board is able to operate with any type of headstage.
Headstages are equipped with Omnetics or single row connectors. Please see table below for an overview
of available headstage types/connectors. For other connector types, adaptors are available on request.
Please contact the MCS support team for detailed information.
Please see the table for the dimensions and weights of the headstages. The specifications apply to
headstages without additional functions.

Each headstage has a battery connector and two LEDs, blue and red. The headstages are coated with
transparent blue material as protection against water and dirt. The standard gain of the headstages
is 100, and the frequency range is 1 Hz to 5 kHz. A lower cut off frequency of 0.1 Hz is available on
request.
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" in the Appendix.
Summary of Sampling Rates per Channel for the four Headstage Types:
W2100-HS4:
25 kHz per channel simultaneously on all 4 channels, also 40 kHz when using
2 channels.
W2100-HS8: 25 kHz per channel simultaneously on all 8 channels, 40 kHz when using
4 or 2 channels.
W2100-HS16: 25 kHz per channel simultaneously on all 16 channels, also 25 kHz when using
8 channels and 40 kHz when using 4 or 2 channels.
W2100-HS32: 10 kHz per channel simultaneously on all 32 channels, 25 kHz when using
16 or 8 channels, 40 kHz when using 4 or 2 channels.
Battery Options
Batteries of the Wireless2100 are always external, not built in the headstage. Standard batteries are
available with different capacities, 30, 100, 200 and 300 mAh. Custom batteries are available on request.
They can either be connected directly on the headstage with a double plug or with a cable connection,
for example, with a backpack on the back of the animal. Backpacks for rat and mice are available as
accessories. Please see the images below.
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. Layers with additional functions are only added on request,
to avoid unnecessary weight and cost.
At the moment, only the basic recording option is available. Optional modules for electrical and optical
stimulation, as well as motion tracking are under development. It will be possible to customize
a headstage when it is ordered, and add additional layers with additional functions. A modification
of already existing headstages is not possible.
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. The position of the antennas can have an influence on the transmission efficiency.
With a clear line of sight between sender and receiver, an effective transmission range of 5 m is
guaranteed under normal circumstances. Under good conditions, the actual range can be much further.
The receiver does not need an own power supply. The device is connected to the interface board via
eSATAp cable for data transfer and power supply.
Wireless2100 Interface Board
The interface board is the third element of the Wireless2100-System. It provides connectors for
additional analog input channels and digital trigger in- and outputs.
The interface board is connected to the receiver with an eSATAp cable. The connection to the data
acquisition computer is realized via USB 2.0 high speed cable. The interface board has an own power
supply.
Front Panel of the MCS Interface Board
Two Status LEDs
The status LEDs indicate the link status of receiver 1 and / or receiver 2. They light up when one or both
receivers are connected to the interface board via eSATAp cable.
Auxiliary Channels
Two reserve auxiliary channels are available for future use. They have no function at the moment.
Digital IN / OUT
A Digital IN / OUT for 16 digital in- and output bits is available (68-pin MCS standard connector) on the
rear panel of the interface board. On the front panel four digital IN and four digital OUT connectors bits
are also accessible via Lemo connector, DIG IN bit 0 to bit 3 and DIG OUT bit 0 to bit 3. If access to more
bits of the DIG IN / OUT channel is required, it is necessary to connect a Di/o board with a 68-pin standard
cable. This Di/o board is available as optional accessory.
Power LED
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.
Rear Panel of the MCS Interface Board
Toggle Switch On / Off
Toggle switch for turning the device on and off. The Wireless2100-System is switched to status "ON"
when the toggle switch is switched to the left. 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.
Power IN
Connect the power supply unit here. This power supply powers both, the headstage and the interface
board of the Wireless2100-System. The device needs 12 V and 2.5 A / 30 W.
Ground
If an additional ground connection is needed, you can connect this plug with an external ground using
a standard 4 mm jack.
Digital IN / OUT
A Digital IN / OUT for 16 digital in- and output bits is available (68-pin MCS standard connector). Please
read chapter "Pin Layout" (Digital IN / OUT Connector) in the Appendix for more information about the
pin layout of the connector. The Digital IN / OUT connection accepts or generates standard TTL signals.
TTL stands for Transistor-Transistor Logic. A TTL pulse is defined as a digital signal for communication
between two devices. A voltage between 0 V and 0.8 V is considered as a logical state of 0 (LOW),
and a voltage between 2 V and 5 V means 1 (HIGH).
The Digital OUT allows generating a digital signal with up to 16 bits and read it out, for example, by
using a Digital IN / OUT extension Di/o from Multi Channel Systems MCS GmbH. You can utilize this
digital signal to control and synchronize other devices with the Wireless2100-System. Bit 0 to 3 of the
Digital OUT are separated and available as Lemo connector DIG OUT 0 to 3 on the front panel of the
interface board. So if you need only one, two, three or four bits of the digital signal, you don’t need the
additional Di/o.
The Digital IN can be used to record additional information from external devices as a 16 bit encoded
number. The Digital IN is most often used to trigger recordings with a TTL signal. The 16 bit digital input
channels is a stream of 16 bit values. The state of each bit (0 to 15) can be controlled separately. Standard
TTL signals are accepted as input signals on the digital inputs. Unused input bits, which have an undefined
state, should be masked in the "Trigger Detector" of MC_Rack.
Warning: A voltage that is higher than +5 Volts or lower than 0 Volts, that is, a negative voltage, applied
to the digital input would destroy the electronics. Make sure that you apply only TTL pulses (0 to 5 V) to
the digital inputs.
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. Signals on
the analog channels are amplified with a gain factor of 2.
Two USB Connectors
Both USB connectors are used to transfer the amplified and digitized data from all data channels and the
additional digital and analog channels to any connected data acquisition computer via USB high speed 2.0
(type A - mini B) cable. Data from one receiver (1) is transmitted via USB connector 1, and the data from
the second receiver (2) via USB connector 2. While using only one receiver, it is not necessary to connect
the second USB.
Important: It is recommended to connect the USB cables to different USB ports of the computer.
Do not use an USB hub!
Audio OUT
To the Audio Out (3.5 mm phone jack) you can connect an audio system to make the electrical activity
audible. This audio output is real-time. Headphones or a speaker can be connected directly to the AUDIO
OUT. Only two channels at a time can be converted into sound (Stereo).
Side Panel
Sockets for connecting up to two receivers via eSATAp cable.
Please use the connector labelled HS/RE 1 when working with one receiver only.
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. With those artificial signals it is possible
to test the functionality of the complete system without the need to use an actual animal. Please read
the ME/W-SG data sheet in the "Appendix" for connecting and operating the ME/W-Signal Generator.
Charging Set
The charging set for the 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 with
the provided adaptor cable W2100-C-B-Ch. The regular charger Wireless-C-HC is used for batteries with
100, 200 or 300 mAh. The charger Wireless-C-LC is used for the 30 mAh battery only.
Important: Charging the 30 mAh battery with the wrong charger can lead to severe damage and even
fire! Do not recharge any battery without supervision!
The red LED on top indicates that the device is on. The yellow LED indicates that the battery is being
recharged. After approximately one hour the green LED indicates the end of process.
Remote Control
The headstages can be switched off with a wireless software command. To reactivate the headstage,
it is either necessary to disconnect and reconnect the battery, or to turn it back on with the remote
infrared remote control Wireless-F. Just point the remote control at the headstage and press the button.
You need to aim at the receiving LEDs next to the battery connector with a distance of 5-10 cm.
System Setup
The following chapter describes how to set up the hardware and software and test the functionality
of the Wireless2100-System.
MC_Rack Installation
System Requirements
One of the following Microsoft Windows ® operating systems is required: Windows 8.1, Windows 7,
Vista, or XP (English and German versions supported) with the NT file system. Other language versions
may lead to software errors.
Recommended operating system settings
The following automatic services of the Windows operating system interfere with the data storage on the
hard disk and can lead to severe performance limits in MC_Rack. These routines were designed for use on
office computers, but are not very useful for a data acquisition computer.
Turn off automatic Windows Update.
Deselect Windows Indexing Service for all local disks.
Turn off Optimize hard disk when idle (automatic disk fragmentation).
It is also not recommended to run any applications in the background when using MC_Rack.
Remove all applications from the Autostart folder.
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. Please remove data and
defragment the hard disc regularly to ensure optimal performance.
Installation
Please check the system requirements before you install the software. MCS cannot guarantee
that the software works properly if these requirements are not fulfilled.
Important: Please make sure that you have full control over your computer as an administrator.
Otherwise, it is possible that the installed software does not work properly.
Double-click Setup.exe on the installation volume.
The installation assistant will show up and guide you through the installation procedure.
Follow the instructions of the installation assistant.
The Wireless2100-System driver and MC_Rack are installed (or updated) automatically. MC_Rack
is updated on a regular basis. Please check the Download section of the MCS website to get the latest
version for free (http://www.multichannelsystems.com/software/mc-rack).
Wireless2100 Hardware Setup
Place the receiver within transmission range of your experimental setup. To get optimal results,
keep the distance as short as possible.
Place the interface board not further then 2 m away from the receiver, and connect the two with
the eSATAp cable.
Connect the power supply to the interface board.
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.
Connect a charged battery to a headstage.
MC_Rack Setup
Start MC_Rack. To define the Wireless2100-System as data source, please open the "Data Source
Setup" in the "Edit" menu.
The "Channel Layout" dialog opens.
Select "USB" in the left "Data Source" drop down menu. The “Wireless W2100” is automatically
selected. 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.
Add the “Wireless W2100-System” via "Edit" menu to the virtual rack.
Click "Hardware" tab.
“Settings” Window of Hardware Tab
Most of the settings are predefined. Click the “Sampling Frequency” drop down menu and select
the desired sampling rate. The sampling rate depends on the type of the headstage and the number
of channels in use. In the example on the upper screenshot an 8-channel type headstage is selected.
When recording with all eight available channels the sampling rate is limited to 25 kHz. Recording
with one to four channels only is possible with a sampling frequency of up to 40 kHz.
“Offset Correction” Window of the Hardware Tab
The “Offset Correction” can be used to correct for offsets caused by the connected electrode. The
“Learn Offset” button detects the difference to 0 on all channels individually. Activating the "Offset
Correction" function will subtract those differences from all incoming data to correct the offset.
„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.
On the right side the "Available Headstages" are listed with type and serial number. Highlight the desired
headstage and click “Select”. The headstage will now be displayed in the "Selected Headstage" window.
The serial number, the type and the status of the battery charging is displayed. Deselect the headstage
by clicking the button "Deselect". The LEDs on the selected headstage will blink, if they have not been
switched off. In the example above the blue LED is in “Blink” mode, the red LED is off.
On the “Channel” list, any combination of channels can be selected for recording. On the screenshot
above, the first 16 channels of the headstage are selected. Deactivation of channels reduces energy
consumption of the headstage and might allow higher sampling rates
A selected headstage which is not recording is in stand by mode, where it uses about 10 % energy
compared to active recording. To shut it down completely, use the “Switch Off” button. A headstage
which has been switched off will no longer show up in a scan. To reactivate it, you need to shortly
disconnect the battery, or use the infrared “IR-Remote Control”. Aim at the headstage from 5 to
10 cm distance.
The LEDs can be used for motion tracking and/or as status indicator of the headstage. They can be set
to “On”, “Off” or “Blink”. LEDs set to “On” will be on all the time on a selected headstage, regardless
of the recording status. If they are set to blink, they will blink slowly in standby mode and faster while
the headstage is acquiring data.
Click the "Info" tab of the dialog.
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. Only two channels at a time can be converted
into sound. Select one "Mono" or two "Stereo" channels, switch the audio channels on and off and
adjust the sound volume via the sliders.
Data Display
Add a data display to the rack
. By default, the available channels will be displayed in numeric order.
To design a display layout which resembles the layout of a specific electrode, select the "Layout" tab
of the display. You can design a grid with a number of rows and columns of your choice. Each electrode
channel can be assigned to any position. Once created, this configuration can be saved as user channel
map (”*.cmp” file) for future use. See below a layout for an electrode with four shanks, with four
electrodes each.
Operating multiple Headstages
It is possible to operate different headstages connected to one Wireless2100-System. The headstages
are discriminated via frequency band for the radio communication. Each headstage is labelled by the
type (W16) and the serial number (S/N 1230). Please see the bill of delivery for the assignment of the
headstage and the frequency band.
Sequential Recordings
After pressing the button “Scan” the receiver scans for available headstages in range. Then the user
is able to select the desired headstage. Click on one of the headstages in the "Available Headstages"
window and press the button "Select".
After recording from the first headstage, deselect the headstage by clicking the button "Deselect".
Now you can choose a different headstage and repeat the process. For sequential recording, the full
sampling rate for the respective headstage type is available.
Parallel Recordings
Operating multiple Wireless2100-Headstages in parallel with one computer is still under development.
It will be possible to run two receivers connected to one interface board, each recording from up to four
headstages in simultaneously.
To control the different recordings independently, start one instances of MC_Rack for each headstage.
In “Data Source Setup” assign the Wireless2100 receivers via serial number to the instances of MC_Rack.
With a maximum of eight instances, it is possible to select a different headstage in each MC_Rack
instance and control the recording independently. Already selected headstages become invisible
for other scanning receivers. When doing parallel recordings, the sampling rate is limited to 2 kHz.
First functional Tests
Set up the Wireless2100 hard- and software as described above. Make sure all components are connected
and the Wireless2100-System is switched on at the interface board. Connect a charged battery and the
ME/W-Signal Generator to your headstage. See the ME/W-Signal Generator datasheet in the Appendix
for details on connector and orientation.
Open the MC_Rack software and build a rack with a Wireless2100 data source and a data display as
described above. At the signal generator, select the signal type “Spikes”. You should see a noise level
of about 20 μV (peak to peak) and a signal amplitude for the largest spikes of 360 μV.
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. A ground electrode is essential, a reference electrode
is recommended.
Battery Options
Make sure that the battery of the headstage is charged and plugged in properly. The battery can be fixed
on top of the headstage or it can be stored in a special backpack on the back of the animal. Batteries are
available either with a cable or fixed on a circuit board with a double connector to be plugged in directly
on the headstage, please see the images below.
Use of the Reference and Ground Electrodes
For optimal signal quality in in vivo experiments it is necessary to provide a good grounding (GND) and a
well placed reference (REF) electrode. Therefore all headstages of the Wireless2100-System are equipped
with dedicated pins for a ground and a reference electrode.
The reference electrode 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).
To make sure that the animal and the headstage are set to the same electrical potential, a ground
connection is also necessary. A good ground option is usually a large conductor, such as a scull screw
or a silver wire implanted under the skin of the animal.
Important: Please connect all unused inputs of the headstage to ground (GND) to prevent floating!
If you do not use all inputs of a headstage, for example, when using a headstage with eight channels
and a probe with four electrodes, the open channels are floating and disturb the recording of the
connected channels. It is necessary to ground the open channels physically. Deselecting the channels
in the “Hardware” tab of the software has no effect.
Positioning of the System Components
If possible, always provide a clear line of sight between the headstage and the receiver and keep the
distance as short as possible. In a larger cage, ideally position the receiver in the centre on top of the
cage. The position of the antennas does have an influence on the quality of the connection, so in case
of connection issues, it might help to play around with the antenna positions. Two out of five antennas
receive data from one transmitter on the headstage. One antenna is for metadata only. In theory, the
ideal position is if the two antennas of one receiver are orthogonal to each other, like in the image below.
However, as the signal is reflected by surrounding objects, the ideal position can be quite different in each
setup.
Optimizing Energy Consumption
The power consumption of the Wireless2100 headstage mainly depends on two parameters: The number
of channels and the sampling rate. To save power, the headstage automatically goes to standby mode
while not acquiring data. To decrease the power consumption while recording the most effective
measures are to decrease the sampling rate as far as possible and switch off channels with irrelevant data.
While not doing experiments, it is recommended to disconnect the battery or switch the headstage off via
software command. It is also possible to decrease the sending power of the transmitters, if the distance
between headstage and receiver is small.
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. This helps other users, and it helps MCS to
optimize the instrument and the documentation.
Please pay attention to the safety and service information of chapter "Important Safety Advice".
Multi Channel Systems MCS GmbH has put all effort into making the product fully stable and reliable,
but like all high-performance products, it has to be handled with care.
Potential Problems
The headstage sends signals to the receiver in 2.4 GHz frequency band. That is why devices, working
in the same frequency band may disturb the data communication between headstage and receiver.
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.
Important: For bandwidth reasons it is not recommended to use an USB hub to connect the
Wireless2100-System to your computer.
Technical Support
Please read the "Troubleshooting" part of the manual or help first. Most problems are caused by minor
handling errors. Contact your local retailer immediately if the cause of the trouble remains unclear. Please
understand that information on your hardware and software configuration is necessary to analyze and
finally solve the problem you encounter.
If you have any question or if any problem occurs that is not mentioned in this documentation, please
contact your local retailer. The highly qualified stuff will be glad to help you.
Please keep information on the following at hand
Description of the error (the error message text or any other useful information) and of the context
in which the error occurred. The more information on the actual situation you can provide, the easier
it is to track the problem.
The serial number of the device. You will find it on the bottom side of the main unit.
The software of MC_Rack version you are currently using. On the "Help" menu, click "About
MC_Rack". The displayed dialog box shows the version number.
The hardware version of the Wireless2100-System you are currently using is displayed in the
“Hardware” tab of the starting dialog.
The operating system and service pack number on the connected computer.
The hardware configuration (microprocessor, frequency, main memory, hard disk) of the connected
computer. This information is especially important if you have modified the computer or installed new
hard- or software recently.
Storage Batteries
Batteries and accumulators do not belong in normal household waste and, thus, must always be disposed
of within the framework of existing legislation.
Please store the batteries absolutely dry at a temperature of about 10 °C.
