our hardware does not have the driver. It is only TCP, not UDP.If I put a single device directly connected to the LAN port (without a LAn switch), when I give the IP number as 192.168.0.154 & port number as 7702 , it works using your Advanced TCP/IP data logger sw.
To log data from 5 IP devices, i connected to a switch. Here I do not know how to configure ypur software.Please help.

I have 5 micro controllers with RS232 port connected to serial port-ethernet converter hardware. Now all these 5 ethernet converted devices configured with individual IPs.
I connected all the 5 devices thru a SWITCH to a PC.from this PC I want to do a TCP/IP data log from all the 5 IPs.

I am able to log from one IP if that device is directly connected to the PC without a switch. if I use the switch for 5 IPs , I dont know how to do datalog.
 
I downloaded a trial from your site - http://www.aggsoft.com a product - ADVANCED TCP/IP data logger.

Please help.
