Best quality Usb To Rs485 422 Converter - Co-Directional 64K-FE Converter JHA-CE1tF1 – JHA
Best quality Usb To Rs485 422 Converter - Co-Directional 64K-FE Converter JHA-CE1tF1 – JHA Detail:
Overview
The G.703 (Co-Directional G.703) interface divides 64Kbps cycle into 4 unit intervals, it uses“0101” represent “0”, “1100” represent “1″. By alternating transformation polarity of the adjacent block, binary signals convert three-level signals. In every 8th group destroyed block of alternating polarity, thus to transmit 8KHz timing signal. By the above coding, G.703 co-directional 64Kbps signal could achieve transmitting the timing signal of 64KHz and 8KHz and 64KHz and the data signal of 64Kbit/s in the same direction with a pair balanced line.
This interface converter provides one co-directional G.703 interface and one Ethernet interface to achieve 10/100Base-T Ethernet data transmission on the G.703 channel. It is a high performance, self-learning Ethernet bridge. This device is the extension device of Ethernet, using network (PDH/SDH/Microwave) that provide G.703 channel to achieve local and remote Ethernet interconnecting with serial interfaces at a lower cost. The device has inter-set loop test function to facilitate the project launching and daily maintenance.
