Multi-Drop Self-Healing Ring Fiber Optic Modem
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
Serial port interface lightning reach IEC61000-4-5 (8 / 20μS) differential mode: 6KV, impedance (2Ω); Common mode: 6KV, impedance (2Ω) standard
Optional AC 220V, DC -48V, DC + 24V, DC power no positive and negative points;
