3-24 VitalSense Operation - Application Program

Establishing RS-232 Communications - Advanced

When there is a failure to communicate via the serial RS-232 cable,

typically the cause is one of two major COM port errors:

• COM port is already in use.

• General communication errors

NOTE: This following procedure requires modification of the con-

figuration file. If you are inexperienced or uncomfortable with this

procedure, contact your System Administrator for assistance.

COM Port Already in Use

The VitalSense Application Program default COM port is COM1. If the

following error appears, the COM1 port must be changed. This is done by

editing the configuration file.

COM port advisory

1 Open the configuration file using Wordpad, Notepad, etc. This file is

located in the VitalSense installation folder:

Program Files\VitalSense\vitalsense.cfg

2 Change the second line in the file to match an available COM port, e.g.,

COM2.

3 Save the file and restart the VitalSense Application Program.
