Product function:The fiber modem is RS422 to fiber converter which realizes
transmission of the RS422 signal on fiber. This product has solved
the problem of contradiction between communication distance and
communication rate of RS422 port. At the same time, it also has
solved the problem of electromagnetic interference, earth link
disturbance and thunder/lightning destruction, thus greatly
enhancing reliability, security and privacy of data communication.
It can be widely used in various kinds of situations such as
industrial control, process control and transportation control, and
especially suited in bank, electric power as well as departments
and systems which have special request to the electromagnetic
interference environment. Features: - Based on self copyright IC.
- Serial date creates receive and send signal automatically.
- RS232/RS485/RS422 interface can be optional by dip switch.
- Serial port supports 0-115.2KBps baud rate auto-negotiation.
- Combination of PDH technology and digital lock loop clock
technology.
- Unique serial port for circuit protection, supporting hot-plugging.
- Data transmission is stable and reliable with integrated
light-receiving and transmitting module.
- Complete surface paste and install craft, industrial grade design,
and production-runs with piece-pasting machine.
