I. Product OverviewYT-5202 is a fiber optic serial data transceiver that can support both 1-way RS232 and 2-way RS485 (or 1-way RS422) interfaces. It is the best choice for connecting a remote terminal unit (RTU) to a host (HOST) or a distributed data acquisition system (SCADA) controller. It supports multiple Asynchronous communication protocols such as RS-232 and RS-485, and can simultaneously use one RS-232, two RS-485 interfaces or one RS422 interface. It supports 2-wire (half duplex) RS-485 and 3-wire RS232 communication. Supports multiple fiber optic connection methods between asynchronous serial ports, and supports devices with two asynchronous serial ports for full duplex (RS232) or half duplex (RS485) communication through fiber optic. The communication distance can reach up to 2 kilometers for multimode and 20 kilometers for single mode, with a maximum transmission rate of 115.2 KBPS for RS-232 signals and 460 KBPS for RS-485 signals. Interfaces with different electrical standards can be mixed, RS-232 devices can be used to connect RS-485/422 devices, replacing RS-232 to RS-485/422 interface converters or photoelectric isolators.
YT-5202 can support synchronous sending and receiving of data, and has an automatic enabling control circuit for data flow. A pure hardware fiber optic transceiver module designed specifically for low-speed serial data transmission and reception in industrial control can achieve almost zero delay in data transmission and reception, greatly improving the compatibility of equipment control software.
