USB-QC30R2 is the programming cable in which the USB interface provides both the serial connection and RS232 signal conversion. Which is application to Mitsubishi plc Under the control of the computer-driven driver, the programming cable makes it possible for the computer’s USB interface to simulate the traditional serial (known as COM interface), thus various existing programming software such as communications software, monitoring software, and other applications can be normally used.
USB-QC30R2 programming cable simulates USB port as a traditional serial port (usually COM3), which enables existing programming software(GX Developer) to communicate through the simulated traditional port and PLC devices.
About Long Distance Communication to USB-QC30R2 doesn’t support long-distance communication. The working power supply of this cable is directly from the USB port, but not the PLC programming interface. The two-color LED on the converter box indicates data’s transceiver status. USB-QC30R2 is applicable to Mitsubishi Q series PLC (Q mode)
Notes and Troubleshoot:
1. If the USB programming cable could not be detected when opening the PC, or some other outstanding issues occur, please re-plug it again.
2.USB to UART is a plug and play USB device. When data are being transmitted, please don’t disconnect it.
3. Sometimes when Windows System failures or outstanding issues when the plug or unplug the USB cable occur, please restart the computer and PLC.
