SRing 2004 4 Channel Serial Data Ring Network Fiber Modem

 Ring Optical data type provides 4 RS232 / 422/485 in the optical fiber transmission, supports a variety of fiber optic network topologies: point-to-point communications, chain network, star and redundant ring network protection, self-healing network topology, and on this basis, the networking is more complex network topologies, with a self-healing ring network protection. The product breakthroughs contradictory legacy serial interface communication distance and speed, but also solve electromagnetic interference, ground loop interference, and lightning damage problems, greatly improving the reliability of data communications, security, and confidentiality.

● Based on a proprietary integrated circuit;

● Provide 1-4 independent serial ports (RS232 / 422/485 optional) channel, physical isolation from each other,  there is no correspondence between the

● Provide two fiber optic lines, it can automatically switch when the line fails, ensuring communication is normal.

● Support a variety of fiber-optic network structures: point to point, star, chain, ring redundancy, and can be combined into more complex network topologies to support a variety of fiber optic network architecture:  Point, star, chain, ring redundancy, and can be combined into more complex network topologies to support a variety of fiber-optic network structure: point to point, star, chain, ring redundancy, Can be combined into more complex network topologies 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.
