Reasonable price Rs232 To Rs485 Interface Converter - Framed E1-FE+4RS232 interface Converter JHA-CE1F1R4 – JHA Detail:
Overview
This protocol converter (interface converter) using large scale FPGA design, providing a framing E1 interface and an Ethernet interface and four serial interfaces, it is possible to achieve 10 / 100Base-T Ethernet data over E1 channels transmission, is a high performance, self-learning Ethernet bridge. The device serves as an extension of Ethernet devices, use of existing networks (PDH / SDH / microwave, etc.) provided by the E1 channels to interconnect both ends of the lower cost Ethernet and serial interfaces. Built-loop test equipment capabilities to facilitate the opening and routine maintenance works.

Features
- Based on self -copyright IC
- Can realize monitor and control of remote equipment, OAM management data did not take up user’s timeslot and save E1 bandwidth
- E1 supports any timeslot set, the rate is 64K-2048K
- The local device can forced the remote device rate follow it
- Have indicator when the remote device is power-off or E1 line is broken or lose signal;
- Have the function of E1 interface loop back check, avoid the converter crashed because of interface loop return;
- The Ethernet interface supports jumbo frames (2036 Bytes);
- Inter-set dynamic Ethernet MAC address (4,096) with local data frame filtering function
- Ethernet interface supports 10M/100M, half/full duplex auto- Negotination, support VLAN
- Ethernet interface supports AUTO-MDIX (crossed line and straightly connected line self-adaptable );
- Have Ethernet monitor self-reset function, the equipment will not dead
- Provide 2 clock types: E1 master clock and E1 line clock;
- Provide 2 impedances: 75 Ohm unbalance and 120 Ohm balance;
- Support SNMP Network Management
- Serial Data Interface can be RS232/RS422/RS485/TTL optional
- Serial channel can transmit adaptable serial data asynchronously 300 Kbps-19200Kbps baud rate
- Serial data multiplexing in E1 support ITU-T R.111 jumping coding mode
- The local RS232 serial data can command the remote RS232 serial data loop-back to the local. This loop- back in the outer ring of RS232 data interface, you can test the RS232 interface chip without damage
- Serial port interface lightning-protection reached IEC61000-4-5 (8/20μS) DM(Differential Mode): 6KV, Impedance (2 Ohm),CM(Common Mode): 6KV, Impedance (2 Ohm) standard
