Help needed to identify it device
Hi all,
I found this strange thing at a car boot and can't figure out what it is or what it does. It's a non-descript plain white box. At the back there are two 9 pin serial type ports, one labelled ptc, the other rs232. It has an rj45 network port and a 12v dc power input. There are two small holes on one side with two leds and a serial number that looks like a mac address. Any ideas?
