Serial Optical Fiber Modem

Industrial Rail Type 8 Channel RS232/422/485 Fiber Modem

Provides 8*RS232/422/485 in the optical fiber transmission support point to point communications and on this basis the networking is more complex network topologies with a self-healing ring network protection. The product breakthrough contradictory legacy serial interface communication distance and speed but also to solve the electromagnetic interference ground loop interference and lightning damage problems greatly improving the reliability of data communications security and confidentiality.
◆ based on proprietary integrated circuit;
◆ Provide 1-8 independent serial ports (RS232/422/485 optional) channel physical isolation from each other  there is no correspondence between the;
◆ Support point to point network topologies 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.
