Demonstration and Test   

In this chapter, we give an example that can be used to test the function of 

EG-SR-7100A. The testing environment is as follows: 

Hardware 

‹

 

PC that has an RS-232 serial port. 

‹

 

EG-SR-7100A & Test board 

‹

 

Ethernet cross-over cable to connect PC's and EG-SR-7100A's LAN ports.. 

‹

 

RS-232 cable to connect PC's COM port with EG-SR-7100A's serial data port. 

 

Software 

‹

 

Windows operating system installed on testing PC. 

‹

 

EG-SR-7100A Configuration tool 

‹

 

Hyper terminal
