The ESport-102 Ethernet device server connects RS232/422/485 serial devices to a 10/100 Ethernet LAN/WAN providing a reliable communications connection. The ESport102 Windows driver installs virtual COM ports in the Device Manager of the operating system. The ESP102 features two DB9M ports, one port supports RS232/422 & 485 and the other only supports RS232. Both ports share a single RJ45 10/100 Ethernet port. The ESP102 can be powered by an external DC power supply or by an optional 9VDC power adapter. An optional DIN Rail mounting kit is sold separately.
