MODEL 218 RS-232 serial Serial Optic Fiber MODEM

1. Summarize Model 218 is a sort of more function and economy RS-232 interface optic fiber MODEM. It is the best choice to connect RTU to HOST or SCADA controller. It used Optic fiber as transfer medium, increase the transfer function of system. Communication equipment abstain menace effective to lightning strike, surge, electromagnetism disturb under the secure environment. 2. Function and Characteristic a) Support RS-232 interface b) Asynchronous, point to point, rate up to 120Kbps c) Support 5V DC input, consumption 2W d) Internal or external power choice e) Working wavelength: 1310nm f) Auto test signal rate, zero delay auto transmit 3. Performance guideline Interface: support EIARS-232 standard Rate: 0-120Kbps Transmit distance: Rs-232 port multi-mode 2KM, single-mode 20KM Working environment: -25℃ to 70℃ 4.
