extend serial transmission distance up to 2-5 km (multi-mode fiber) or up to 20-120 km (single- mode fiber).
Introduction:
The Model271 Series converter is equipped with a multiple interface circuit that can handle RS-232, or RS-422/485 serial interfaces and multi-mode or single- mode fiber. Model271 converters are used to extend serial transmission distance up to 2-5 km (multi-mode fiber) or up to 20-120 km (single- mode fiber). Note that the RS-232 and RS-422/485 interfaces cannot be used on the same Model271 at the same time to convert to fiber. Auto Baud Rate Detection.
Features:
1. Auto sense serial signal rate, zero delay automatic transmit
2. 500Kbps the highest baud rate
3. Supply three interface (RS232/485/422)
4. Multi-mode 2KM, signal-mode 20~120KM
5. Compact Size
6. Decreases Signal interference
7. DIN Rail or Wall-mounting
