Based on proprietary integrated circuit;
Provide 2~8channel independent serial ports (RS232/422/485 optional) channel, physical isolation from each other, there is no correspondence between the
Provide two channel fiber optic links, it can automatically switch when the line failure, ensuring communication is normal.
Support a variety of fiber-optic network structure: point to point, star, chain, ring redundancy, and can be combined into more complex network topology to support a variety of fiber optic network architecture: Point, star, chain, ring redundancy, and can be combined into more complex network topology to support a variety of fiber-optic network structure: point to point, star, chain, ring redundancy, Can be combined into more complex network topology electrical interface uses a separate power supply module, completely isolated from the ground loop between the bus and the device; while using optical isolation technology, isolation and internal communications bus data signal, Effective protection of the communications equipment from power surges and ground loop interference and sabotage
RS232/485/422 interface, optional three data, RS232 supports 3-wire RS232 (TXD, RXD, GND), flow control support CD, DSR, CTS,
RS232 / 485/422 channels can be transmitted from 0-115200 baud asynchronous serial data adaptive
