UOTEK USB to RS485/422 Cable Converter 4.9FT - USB 2.0 to DB9 Serial Port with Surge and ESD Protection

As the PC industry growing, most of the low speed external ports are replaced by USB port. In industrial environment, lots of important equipments still adopt RS-485/422 interface design. With this, most of the users use USB to RS-485/422 converter to transmit the data between PC and RS-485/422 equipments.

UT-890A is a universal USB to RS-485/422 converter. There is no need external power; it is compatible with USB and RS-485/422 standards. UT-890 enables to convert USB signal to balanced differential RS-485/422 signal. It provides each wire with surge protection; the tiny interelectrode capacitance ensures high speed transmission for RS-422/485 ports. RS-485/422 adopts DB9 male as connector; internal zero delay auto receiving and transmitting function, unique I/O circuit auto control data flow direction without any handshake signal (RTS, DTR) ; there is no need jumper wire setting for full duplex (RS-422) and half duplex (RS-485) mode, plug & play. All these ensure that it is compatible with all the communication software and interface hardware.

UT-890A provides connection for point to point, point to multipoint communication. For point to multipoint mode, each converter is allowed to connect 32 sets RS-422 or RS-485 device with baud rate 300-921.6Kbps. The power and data flow indicators show the status of the communication.


Matching terminal block Convenient for customers to connect and use.	Interfaces USB A male, DB9 male and DB9 female terminal block.	Magnetic ring on USB input side Wire braiding shielding to prevent interference.
