Ⅲ. Product List    

DT-5028 20m usb extension cable supports all USB2.0 standard equipment: camera, mouse, keyboard, card reader, U disk, USB barcode scanners, and other digital devices. 

DT-7023 DVI splitter is the perfect solution for anyone who needs to send one video signal to 2 displays at the same time.

DT-7026 supports 4 input 2 output, can connect to 4 HDMI sources and switch among them to 2 displays. With remote controller

This universal USB2.0TORS422/RS485 converter requires no external power supply and is compatible with JSB2.0, RS422 and RS485 standards. It can convert a single end USB signal into a balanced differential RS422 or RS485 signal, providing a surge protection power of 600W per line. And various reasons of the surge voltage generated on the line and minimal electrode capacitance to ensure the RS422/RS485 interface high-speed transmission, RS422, RS485 end through the DB9 male connector. Internal converter with zero delay automatic transceiver conversion, onlySome /○ circuits automatically control the direction of the data flow without any handshake. For example, (such as RTS, DTR, etc.) no jumper cable Settings to achieve full duplex (RS422), half duplex (RS485) mode conversion, plug and play. Ensure that all existing communication software and interface hardware is suitable.
