DL3000-DR1
Ethernet to DH+

DL3000-KFX: The DataLink DL3000-KFX is DataLink’s latest serial DF1 to DH+ interface. Using A-B's standard DF1 driver, the DL3000-KFX will interface any computer or control device to DH+ networks running at 57.6 or 115.2 Kbaud. While functionally similar to the DL2000-KFX, the DL3000 is much smaller, weighs just over 0.5 lbs, and supports serial baud rates of up to 230.4 Kbaud. The unit is desktop or DIN rail mountable, and with an optional AC to DC adapter is ideal for use with a laptop or mode

Lantronix Software DeviceComm Manager Software is a free COM port redirection software application for PC platforms. Its function is to redirect customer application data destined for a local serial (COM) port on a PC.Rather than going out the local port, the data is transmitted across the Ethernet network using TCP/IP. A Device Server attached to the network receives the data and presents it on its serial port. Conversely, data into the serial port of the device server is sent back to the customer application via the network to the DeviceComm Manager. The DeviceComm Manager then presents the data to the customer application as if it were from a local serial COM port.
