Serial Communications Protocol 

A 9 pin RS-232 connector (see earlier section 

“

Serial Communications 

Port

”) provides two-way communication between the Laser Photometer 

and microcomputer. The default serial communication protocol is 
presented below. A baud rate of 1200 is the default. A baud rate of 115K 
can also be set. The low baud rate default has been selected to meet 
existing requirements for the Model 8587 operated with older software.  
 
Baud rate: 

1200 

Data bits: 

8 

Stop bits: 

1 

Parity: 

none 

Handshake: 

none 

 
A single cable from the computer to each photometer is required to enable 
communications. 
 
A terminal emulator program such as HyperTeminal provided with 
Windows can be used to send and receive serial data.  
 
Change baud rate from 1200 to 115K by holding Upstream key for 5 
seconds. Use the Downstream key to select the baud rate. Save and exit 
using the Purge key.   

USB Communications 

Note:

  Do 

not

 plug your device (Laser Photometer) USB cable into your 

computer before the USB driver program is installed.  

 
Before USB communications can be used, a TSI USB 

driver

 program must 

be installed on your computer. Install the program using the CD supplied 
with your instrument. Refer to 

Appendix B

 for instructions on installing the 

driver. 
 
Once the driver is installed, USB communication is achieved by simply 
connecting your laser photometer USB connection to the USB port on your 
computer using the supplied USB cable, type B connector.  

USB Terminal Emulator Program 

Note:

  Do 

not

 plug your device (Laser Photometer) USB cable into your 

computer before the USB driver program is installed.  

A USB Terminal Emulator program is provided on the CD supplied with 
your Model 8587A. This enables you to, send and receive ASCII 
characters for external instrument control and data acquisition.  Refer to 

Appendix B

 for information on installing and using the USB Terminal 

Emulator program.
