The same working principle is applied in the opposite direction, too.
At the secondary windings, the induced waveforms are decoded back into the digital values and routed to the pins, with the appropriate TTL/CMOS voltage levels. RS232 level inputs are inverted and encoded into waveforms that are used to energize the primary windings of the integrated transformers. This integrated circuit features four integrated galvanic isolation elements that provide the required isolation level. The main active component of the RS232 Isolator click is the ADM3252E, an integrated dual-channel RS232 driver/receiver, with the i Coupler® isolation technology, made by Analog Devices. This is very different than the CMOS/TTL voltage levels used on many MCUs and other types of commonly used modern devices, so the first task of the RS232 isolator board is to provide appropriate RS232/TTL levels. The logic voltage levels used by the RS232 can go up to ☑5V with respect to the common ground. After several reviews of this standard and t hanks to its simplicity and past ubiquity, RS232 is still being used - particularly in industrial machines, networking equipment, and scientific instruments where a short-range, point-to-point, low-speed wired data connection is required.

It became very popular during ’90s, as it became an integral part of many PC motherboards.
#Rs 232 optical isolator serial#
The RS232 is a serial communication standard, which was first introduced in ’60s. RS232 Isolator click can be used for galvanic isolation of RS232 signals, whenever there is a need for that kind of isolation - operating in harsh environments where electrostatic discharges (ESD) can occur, when the RS232 cable is plugged in and out frequently, and generally - wherever the sensitive part of the RS232 controller logic circuitry needs to be protected. The digital input and output signals are transmitted across the isolation barrier by utilizing the Analog Devices proprietary iCoupler® technology - IC scale transformer windings couple the digital signals magnetically, from one side of the barrier to the other, providing the galvanic isolation and transfer rates up to 460Kbps. RS232 Isolator click is a fully isolated dual transceiver click, used to provide secure and easy UART to RS232 conversion, with the galvanic isolation.
