Through the Internet, data acquisition and control may now be performed! All that is required is a host PC running the
SelmaWare Serial/TCP Gateway program included with this distribution to make the data transition from Internet to serial and vice-versa.
After running the program from the Start Menu, the IP of the local (host) computer will be displayed. The default port is 9001.
An optional password for connection may be entered. The program will disconnect the client computer after the number of minutes indicated. (The non-registered version of
StampPlot does not allow times greater then 3 minutes)
 | Configure the COM port setting accordingly for your micro. |
| Connect on the serial port. |
| Click Listen to begin listening for a TCP connection. |
That's it! Your are ready for transparent communications over the Internet!
StampPlot Client: (See Configuration -Port)
| On the Plot client, In the Configuration Window, Port Tab, select TCP. |
| In the IP box, type the IP of the Gateway Host, and change the Port and enter a password if required. |
| Connect on StampPlot |
That's all! You are ready to connect and start plotting over the internet!
!PORT TCP, IP, port,password
!PORT 127.0.0.1,9001
Notes:
Data transmission over the internet can be very different than direct serial. Data
packets may be broken up, separate packets may be combined, and it takes longer for the data to reach the destination. While
StampPlot handles most of these problems, if the micro is waiting for data to return, you may have to increase the timeout on the order of 0.5-1.0 seconds, and if your micro echo's data back, again, you may need to increase the delay before sending new data.
Other than that, it should all be fairly transparent to the user!
