Radical-7 Signal Extraction Pulse CO-Oximeter Operator’s Manual 4-31

Trend Setup and Use

INTRODUCTION

The Radical-7 can store up to 72 hours of trend data captured at 2 second intervals. The trend

data can then be transferred to a PC for evaluation.

A serial cable is required to connect the Radical-7 to a PC.

Trend data is stored in non-volatile memory, so it is not erased when the instrument is shut off.

A trend data download is initiated using the TrendCom utility which downloads the trend data and

saves it to an ASCII text (.out) file with an output delimiter option.

TRENDCOM UTILITY INSTALLATION

Copy the TrendCom utility from the TrendCom CD (not included) onto a PC running

MS-Windows.

TRENDCOM UTILITY OPERATION

NOTE: Ensure the appropriate USB-Serial software driver is installed on the PC, if using a USB-

Serial cable. PC must have Excel

spreadsheet software, or another program capable of using a

.csv (comma separated value) file to view trend information. Information can be viewed as a .txt

file. Trend information data is limited by the instrument's parameters.

Download Trend Data from Radical-7

A) Attach the USB-Serial or Serial-Serial Cable

NOTE: The Radical-7 handheld must be attached to a docking station. If using a USB-Serial

cable, connect the serial cable from the RS-232 serial port on the back of the docking station to

a USB port on the PC. If using a Serial-Serial cable, connect the cable from the RS-232 serial

port on the back of the docking station to a serial port on the PC.
