* When using DB-UC001-A separately, if the device connected to DB-UC001-A can provide 5VDC power from mini USB port, it can work well. If not, it will not work. You should supply 5VDC from connectors to DB- UC001-A. If the device can supply 5VDC for DB-UC001-A, please don’t supply 5VDC in addition. USB to RS232 Module are manufactured by Sure Electronics. It uses the CP2102 that is recommended for all new designs, and is a pin-compatible upgrade to the CP2101. The CP2102 is a highly-integrated USB-to-UART Bridge Controller providing a simple solution for updating RS-232 designs to USB using a minimum of components and PCB space. The CP2102 includes a USB 2.0 full-speed function controller, USB transceiver, oscillator, EEPROM, and asynchronous serial data bus (UART) with full modem control signals in a compact 5 x 5 mm QFN-28 package. No other external USB components are required. Notice: Never feed +5V power to DB-UC001-B, when combined with DB-UC001-A Never use J2 and J4 to connect in the meantime
