The ComNet(TM) CN FE2DOE 2 allows any combination of two RS -232, RS -422, or 2 or 4-wire RS -485 serial data circuits to be inserted onto any 10/100 Mbps Ethernet-based network. Basic flow control/handshaking (Request-to-Send & Clear-to-Send) is inclu ded, when this device is used with RS 232-compatible equipment requiring this functionality. The CN FE2DOE 2 includes two serial data input/output ports, and two Ethernet ports; one accepting an SFP (Small Form Factor Pluggable), and the other an RJ45. The two serial ports may be configured by the user for communicating from one port to the other through either the user's network, or via a PC. It may be used as a protocol converter (serial data to Ethernet) or as a media converter, for converting co pper transmission media to fiber. Serial data appearing on either of the two serial data ports is converted to Ethernet, and transmitted to both the SFP and RJ45 ports, permitting the unit to be simultaneously used as a media converter and a terminal s erver. A remote user and a local user can access at the same time local serial data devices connected to the serial data ports. Configuration of this device is performed through its internal web server. By selecting the appropriate ComNet SFP, a copper or optical interface may be used to achieve the desired optical transmission distance, using one fiber with WDM, or two separate multimode or single-mode fibers. These models require the ordering of sold-separately interchangeable SFP modules for fibe r type, distance and connectors. A software utility feature allows the user to locate other CN FE2DOE 2 terminal server devices installed within the same subnet, and to create virtual communications ports for each serial port on the device. Com0com sha reware is also included, allowing the user to create a "virtual" serial port on their PC, and then connect the PC to a TCP /IP connection using the com2tcp utility. The use of these two utilities enables communications through an Ethernet network to th e CN FE2DOE 2, and provides control of the remote hardware, as if it were connected directly to the PC CO M port. Packaged in the ComNet "middle-sized" housing, the CN FE2DOE 2 is ideal for those installations where space may be limited, and it may be DIN -rail mounted by the addition of the DIN BKT1 Adaptor Plate.Caractéristiques
