APPENDIX F – RS232 COMMUNICATIONS (IF EQUIPPED)

 

  

If the instrument is equipped with the RS232 Communications option, there will 

be a three pin male connector on the bottom of the instrument.  Also, an RS232 

cable will be included with the instrument.  This cable will have a three pin 

female connector on one end and a DB9 Female connector on the other end. 

 

RS232 Data Output – Instructions for Use 

 

 

STEP 1:   Connect the RS232 cable (included) to the female connector on the 

bottom of your instrument.  Connect the other end to an RS232 port 

on your computer. 

 

 

STEP 3:  Turn the Instrument ON. 

 

STEP 4:  Verify that the Instrument has been set up as a RS232 Serial Port 

with a unique COM port number. (You only need to do this once).  

For Windows users, open the Windows Device Manager (found in 

Control Panel) and verify that a serial port exists. 

 

 

You are now ready to capture the data being measured by your 

instrument. 

 

 

Please refer to 

Appendix G – Viewing and Capturing Data

 for 

further instructions.
