IX-228
IX-228S
Overview
The IX-228 Data Acquisition System has 10 input channels and a low voltage
stimulator. The IX-228S adds an isolated high voltage stimulator. Channels 1 and 2
can be configured for isolated recording of biopotentials or as DC-coupled inputs.
Channels 3 though 10 each include a transducer amplifier. This recorder exhibits
the high resolution and low noise required for small animal cardiovascular
research, oocyte clamp, and high-end metabolic research applications.

High Voltage Stimulator (on IX-228S): Suitable for applications ranging from
human striated muscle studies to pacing a rodent’s heart during pressure-volume
loop recording. Connected via HV safety connectors.
CH1 and CH2: Suitable for DC recording and biopotentials. Two-channel
configuration of the bioamplifier allows simultaneous recording of any combination
of ECG, EMG, or EEG signals. A range of high-pass filters (DC, 0.03, 0.3 Hz) and
low-pass filters (10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 150, 200, 300, 400, 500,
600, 700, 800, 900, 1000, 2000, 3000, 4000, 5000, 6000, 7000, 8000, 9000,
10000, 20000 Hz) can be chosen in LabScribe2. Connected via the C-AAMI cable.
Channels 3 through 10: Each channel is equipped with a transducer amplifier to
allow connection of virtually any physiologic transducer via a DIN8 connector.
Low Voltage Stimulator: Parameters for the stimulator, such as pulse width,
frequency and amplitude, may be changed “on the fly” using handy controls
located in the LabScribe2 software toolbar. Standard protocols include Pulse,
Train, Step, Triangle, and Ramp. BNC connectors.

How to Use the IX-228/S
The IX-228/S is controlled by LabScribe2 recording and analysis software.
LabScribe2 has an intuitive interface for setting up acquisition screens, calibrating
signals and analyzing data on up to 128 channels simultaneously at sampling rates
as high as 100K samples/second.
For teaching, LabScribe2 includes dozens of laboratory exercises, categorized by
subject areas. Each experiment contains a preconfigured Settings file and a
detailed pdf file with complete instructions for student data recording and analysis.
For research, LabScribe2 uses a comprehensive set of preconfigured analysis
routines, making analysis and interpretation quick and easy. Specific analysis
modules are able to analyze pressure signals, blood flow data, ECG recordings,
ventricular PV loops, and sonomicrometry dimension data.

To set up and start to use the IX-228/S:
1) Download LabScribe2 from www.iworx.com or load the LabScribe2 software
from the provided CD onto the computer. Be sure to install the software before
connecting the hardware for the first time.
2) Plug in and switch on the IX-228/S.
3) Double-click on the LabScribe2 shortcut to open the software. You should see
a message indicating that the IX-228/S has been recognized by the software.
4) If you are using the IX-228/S for teaching, load the appropriate Settings group
and select an experiment. The experiment should open with LabScribe2
preconfigured with appropriate settings. Follow the instructions on the
accompanying pdf to perform the lab exercise. There is no need to configure
the settings manually.
5) If you are using the IX-228/S for research, you can use the preconfigured
Research settings. It is also possible to create your own Teaching or Research
Settings files. Plug your transducers into the appropriate channels. Channels 1
and 2 are designed for transducers or electrodes requiring DC voltage settings
or a biopotential amplifier. They must be connected via the C-AAMI cable,
connected with pins into the Channel 1 and 2 inputs at the end of the cable.
Channels 3-10 include a transducer amplifier and receive the range of iWorx
transducers with a DIN8 connector.
6) The Channel 1 and 2 inputs can be configured in one of two different software
locations. In the LabScribe2 Preferences (in the Windows Edit menu, and the
Macintosh LabScribe2 menu), clicking on either Channel 1 or Channel 2 will
open an input configuration dialog. In the recording window itself, if you have
turned on Channels 1 and/or 2 in the Preferences, you can access this same
dialog by clicking on the channel bar just to the right of the channel name.

7) Choose one of the preconfigured modes or click on Input Manager to open a
dialog that allows you to choose the appropriate filters and input range for
your experiment. If you wish to create your own mode, click on New and
name the new mode in the text box. Click OK.

8) Return to the Input Manager dialog and choose your mode from the Current
Mode list. Choose the appropriate high-pass filter, low-pass filter, and input
range from each of those dialogs. Click OK.

9) Connect any other transducers to the Channels 3 though 10 DIN8 connectors
and turn those channels on.
10) If you are using the Low Voltage Stimulator or the isolated High Voltage
Stimulator (on the IX-228S), connect your stimulating electrodes to the
appropriate stimulator and use LabScribe2 to control the stimulator as
instructed in the LabScribe2 manual.
