Product Description

RS - 232 / RS - 485 / RS - 422 serial fiber optic modem

RS - 232 / RS - 485 / RS - 422 serial fiber modem, uses the industry standard design, the wall exterior design support - rail DIN standards guide installation, installation is simple. sc168 can provide the user with the RS - 232 / RS - 485 / RS - 422 serial port end-to-end transparent transmission. as a result of optical fiber transmission, the optical fiber transmission of optical signals, there is no electrical conductivity, and thus has a strong anti-interference ability, will not be affected by high voltage and lightning.
product features:
low automatic detection rate of serial port, discrimination and control data transmission direction;
low data transmission rate of 0 to 115.2 kbps adaptive;
low adoption of advanced communication code clock recovery technique to realize in time, ensure signal integrity;
integrated optical transceiver module, the output optical power is stable and reliable;
transparent communication, users do not need any debugging, plug and play;
adaptive low specific interface technology, without having to switch settings, arbitrary switching RS - 485 / RS - 422 interface;
where has the function of automatically detects the signal rate;
low RS - 485 signal zero delay automatic forwarding;
single-ended 9 V power supply, the other end of the 5 VDC - DC power isolation 3000 V, without a serial port for electricity;
low signal transmission using 3000 V high speed optical isolation and pre-emphasis technology;
low communication distance is 3000 meters (9600 BPS);
low support 32 points polling environment (customizable 128 points);
interface with 1500 w surge protection, 15 kv ESD protection;
and 485/422 uses RJ45 interface forms, the COM to choose five terminal;
low installed support DIN - rail guideway and plate.
performance indicators:
standard: in accordance with the eia RS - 232, RS - 485, RS - 422 standard;
the RS - 232 signal: the tx and rx, gnd;
the RS - 485 signal: d, d -, gnd;
the RS - 422 signal: r, r -, t, t -, gnd;
receiving sensitivity: better than - 36 dBm (ber < e - 11)
works: asynchronous job, point to point or multipoint, half duplex 2 line, line 4 full duplex
direction control: uses the data flow automatic control technology, automatic discrimination and control data transmission direction;
wave rate: 300-115200 BPS, automatic detection rate of serial port signals
load capacity: support 32 points (128 points) can be customized polling environment
transmission distance: RS - 3000 meters (9600 BPS) 485/422 end, RS - 232 side suggest no more than 5 m
interface protection: 1500 w 15 kv surge protection, static electricity protection
photoelectric isolation: 3000 V; interface features: meet the itu - t V. 24 standard
