2GE+4RS232/422/485 Fiber Media Converter

Type:FCM-G2R4 Message

Description:single core optice fiber transmission 2 * 10/100/1000M network port and 4 * RS232/422/485 interface

Product Description
                 The device is Ethernet IEEE802.3 media transceiver to achieve media conversion or extending network transmission distance between two kinds of media, which are 10/100Base-T UTP and 10/100/1000Base-FX or 10/100/1000 Base-T UTP and 10/100/1000Base-FX and 4 channel RS232/422/485 serial device , the design is excellent for keeping your industrial automation applications running continuously. And each converter comes with a  relay output warning alarm to help prevent damage and loss. All the models are subjected to a 100% burn –in test, and available in models that support a standard operating temperature range of 0 to 50 °C.
Functional Properties

Ø Automatically adapt to 10Mbps and 100Mbps environment, upgrade network easily;

Ø Device provides 2 Ethernet UTP,4 RS232/422/485 serial port. 1 Ethernet optical port

Ø Support full-duplex and half duplex network communication, with auto-negotiation capability;

Ø The Ethernet interface supports jumbo frames (1916bit), which can match with the switch product complied with IEEE802.10 protocol

Ø Division of VLAN base PORT, this method does not affect the remote device

Ø 802.1Q VLAN Division, at this time, the local and the remote interface can be divided into the same VALN

Ø Provide 4 expansion interface, you can extend 1~4Channel asynchronous data, such as RS232/RS485/RS422/Manchester code;
