How Do I Communicate with the Modbus Demo Box?

Hardware: Industrial Communications>>Fieldbus

Problem:

I cannot find the appropriate settings for communicating with the MODBUS demo box.  What are the serial port settings and RTU address for the box?  Which type of serial cable do I use? 

Solution:

The Modbus demo box responds to the following serial port settings:

• Baud Rate: 9600
  
• Parity: None
  
• Data Bits: 8
  
• Stop Bits: 1

The available addresses are listed on the demo box. The LED that is labeled 1 is register 1, the POT labeled 40001 is register 40001, etc.

The demo box works with a straight through serial cable.
