UOTEK Mini RS232 to RS485 Converter Adapter RS-232 to RS-485 Serial Converter Port-Powered UT-201B

Small Size, Strong Function!

The converter is compatible with RS-232 and RS-485 standards and is capable of converting single-ended RS-232 signals to balanced differential RS-485 signals.

The converter can extend the RS-232 communication distance up to 1.2 km without external power supply. It is driven by a unique "RS-232 charge pump" and does not require initialization of the RS-232 serial port to obtain power.

The unique I/O circuitry automatically controls the direction of data flow without any handshaking signals (e.g. RTS, DTR, etc.), thus ensuring that programs written in RS-232 half-duplex mode can be run in RS-485 mode without modification, ensuring that they are suitable for existing operating software and interface hardware.

It can be used to form a point-to-point or point-to-multipoint remote multi-computer communication network between master controllers, and between master controllers and microcontrollers or peripherals to realize multi-computer answering communication.

It is widely used in industrial automation control system, one-card, access control system, parking system, self-service banking system, company attendance management system, highway toll station system, etc.

It is widely used in industrial automation control system, access control system, parking lot system, self-service banking system, highway toll station system, etc. It can be used to form a point-to-point, point to multipoint remote multi computer communication network between the main control computers, between the main control computer and the microcontroller or peripheral devices. The internal system is equipped with zero delay automatic transceiving and transmitting conversion. The unique I/O circuit automatically controls the direction of data flow without any handshake signals (such as RTS, DTR, etc.). The transmission rate of the converter is 300-115.2Kbps, which can extend the RS-232 communication distance to 1.2km,. The converter is compatible with RS-232 and RS-485 standards, and can convert single ended RS-232 signals to balanced differential RS-485 signals.
