USB to Mitsubishi PLC Adapter

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 and easier user interface. The UR23/42/48 adapter can be embedded into 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 one PC or USB hosts can communicate with each other PLC or serial device 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.
