Product introduction
The ADM-3142 series is a serial port to optical fiber converter, which has the ability to transform serial ports (RS-232 or RS422/485) and optical fiber (multimode or single mode) signals. The ADM-3142 interface converter can extend the transmission distance of the serial port to a maximum of2 km(multi-mode fiber) or20 km(single-mode fiber).
ADM-3142 serial port fiber MODEM can connect remote terminal unit (RTU) to host (HOST) or data acquisition system (SCADA), support PPI, MODBUS and other communication protocols.35 mmstandard rail installation, DC9~48V power supply, excellent performance, work stability, can meet the industrial environment.
Product features
1. Fiber interface support double fiber (SC/ST/FC) or single fiber (SC/ST/FC)
2. Serial port support 2Ch RS485 or 1Ch RS422 or 1Ch RS232 interface
3. When used, it can be one side RS-232, one side RS-485
4. Zero delay automatic forwarding, asynchronous point to point transmission
5. Automatic detection serial port rate
6. RS485 rate 0~250Kbps, RS232 rate 0~115.2Kbps
7. Interface provides 600W surge protection, 15KV ESD protection
8. DC9~48V power supply
9.35 mmDIN rail installation
