I am working with Ethernet based devices, similarly to http://www.rfcode.com/rfid-reader-inventory-tracking-system-m250-fixed-reader. Unfortunately, type of the devices I am using, have been out of production for number of years, and manufacture does not sell or support them anymore.
At work, we have pair of those devices and they work fine and show up on software provided by manufacturer at two different IPs: 192.168.69.240:6500
and 192.168.69.241:6500
So, I took one of the devices home with me and connected it to my PC through the Ethernet (direct connection, bypassing my home router). Tried various IPs, including the ones above and manufacture recommended IP.
My question: How can I find out IP address of the device that is connected to my PC through the Ethernet ? Running on Windows 7.
Clarification: At work, devices are plugged into into a network switch.
Edit(some additional information): At work, I connected the device, same way, I had it at home (PC was off company's network) Surprisingly, device with IP 192.168.69.240:6500
worked fine. Took the same device back home, it didn't work ! Later on today, I will try different PC.
