Chapter 4: Software Setup
\
Figure 4-24. COM1 setup—TCP server.
NOTES:
1. The default port number for the LES301A is 4660 and it is associated with serial port COM1 respectively. After your application
program connects to the TCP port 4660 of the LES301A, data sent to this TCP connection from your application program is
transparent to the LES301A’s COM1. The opposite is also true.
2. The serial interface will show a different port interface according to the model of the serial server.
4.3.5 Configure the LE301A As a TCP Client
Configure the LES301A as a TCP client, for example, the destination IP is 10.0.29.11, and the destination port is 4660.
1. Input destination IP “10.0.29.11”
2. Input destination port “4660”
3. Input idle time at the “Please input idle time to send TCP alive packet( sec):” prompt. (If you input 4, the sending TCP
keep-alive packet period will change to 4*10 sec.)
4. Select “TCP Connect On Power-on” to keep trying to establish a TCP connection after Power on.
5. Select “TCP Connect On Any Serial Character,” and any serial character will trigger to establish the TCP connection.
6. Input idle time to disconnect at the “Serial Inactivity Time before disconnect (0sec , 1–255):” prompt. Input “0” to disable the
function; input ”2” and the serial Inactivity beyond 2 sec will cause a disconnect.
