UR23/42/48 USB to Serial port Adapter Your Best Solution for PC-to-PLC Communication
Overview The UR23/42/48 USB-to-Serial port adapter is a low-cost high-performance single chip solution that provides bi-directional connectivity between any standard USB compliant host systems with another serial device. Unlike previous file transfer methods like serial cable, parallel cable and IrDA, the UR23/42/48 adapter has a more advanced bus protocol and operation system that offers much higher bandwidth ndwidth and easier user interface. The UR23/42/48 adapter can be embedded in the link cable. Both sides of the cable function as an upstream connector that could join a USB network such as the USB port of a PC or the downstream port of a USB hub. Through switching and protocol adjustment in the controller chip, any PC or USB hosts can communicate with other PLC or serial devices while adopting maximum speed for bulk-type data formats. In addition, data are allowed to flow in both directions simultaneously without compromising on performance. Both PC and PLC can control the device using standard serial command; the data flow is directed by a vendor-specific scheme.
