Single-mode fiber OPT485S9 RS-232/485 / converters, ultra-small the electrons OPT485S9 of uses Boshi RS-232/485 / single-mode fiber converters can achieve the function of the RS-232 or RS-485 single-mode fiber conversion, and DB-9-pin RS-232 port can be directly extrapolation. Patented product, has ZL03335086 Chinese patent. As a result of the optical fiber as a communication transmission medium, high isolation voltage, anti-electromagnetic interference, anti-lightning, etc.. Boshi fiber converters are widely used in a variety of industrial process control, distributed data acquisition and other occasions, particularly suitable for power system automation, traffic control and other departments. Second, the hardware install OPT485S9 type RS-232/485 / fiber optic converter (single-mode) the shape DB-9/DB-25 adapter box size, which the DB-9 (Hole Block) at one end can be directly inserted in the DB-9 core RS-232 pin base terminals on the RS-485 signal lines and external 5V power supply using the product. The products use the ST fiber optic connectors, TX optical transmitter the head the RX optical receiver head logo to see product map. OPT series of fiber converters use the transmitter receiver connected to each other through the optical fiber. Pay attention to maintaining clean fiber converter ST Block, If you do not connect sure with matching rubber stopper cover. Third, performance characteristics Boshi electronic OPT485S9 fiber converters highest rate of 115.2Kbps. Without any initialization settings! Unique Boshi zero delay automatic transceiver conversion technology to ensure suitable for all software! OPT485S9 hole DB-9 end direct extrapolation PC, DB-9-pin RS-232 port (needle seat), only use the computer RXD -2, TXD-3, GND-5 three signal lines. RS-485 signals A, three GND, B, wiring terminals (pictured). ST (multimode) fiber optic interface electrical interface DB-9 female RS-232 (outer pin Block) transmission medium dual multimode fiber terminals RS-485 as well as the power of communication RS-232/RS-485 size and weight of the DB- 9/25 adapter size, 80 grams asynchronous RS-232 transmission distance 40Km (single-mode) optical wavelength 1310nm (singlemode) the applicable optical fiber 50/125, 62.5/125, 100/140um four shape Tu Boshi electronic matching each kinds of length single-core, dual-core optical fiber, and ST, FC, SC connector. Note Do not use both RS-232 and RS-485. OPT485S9 products supporting 5V power supply (4.5 V to 5.5V), power consumption is less than 100mA.
