Slow data
Temperatures 14 bits,
Rates 14 bits,
Blood pressures 10 bits,
Analog output of slow data
Data is shifted to a 12 bit value to maximize use of the output range: 0 – 5 V for 0 –
4096 counts.

Capturing ASCII slow data from the serial output

ASCII values from any of the 4 serial output channels can be read and displayed on a
PC using HyperTerminal as follows:
1. Make an appropriate selection for the connection com number.
2. Set the following port settings: 115200 Bits per second, 8 Data bits, Parity None,
Stop bits 1, Flow control None.
3. Select File>Properties>Settings>ASCII Setup>ASCII Receiving.
the following are not checked: "Append line feeds..." and "Force incoming data
to 7-bit ASCII". Check "Wrap lines that exceed terminal width".

Capturing ASCII waveform data from the serial output

Waveform data streams from the serial port at a rate of 1800 8 bit bytes per second.
Waveform data is digitized using a 10 bit A/D, so 2 bytes contain a single measurement.
WaveGrab.exe can be used to capture the waveform data using a serial or USB PC port
and write it as a text file with 900 samples per second. The text file can then be
imported into a spread sheet program such as Excel.
To run the software, click on the WaveGrab icon on the desktop.
WaveGrab is executed on a PC an authorization code is required to activate the
software. The PC's ID code must be transmitted to SA instruments and then an
authorization code for that PC can be entered to activate WaveGrab.
