====== AMBrc decoder not found ====== === Configuring the right serial port === AMBrc decoder must use the serial port to connect with. If your PC/Laptop has not a serial port you will need an USB/Serial convertor. The comm port name will depend on the USB slot you use. Windows device manager can be used to see what serial comm port name is assigned to the USB/Serial cable. Use this name into the ZRound AMBrc configuration page. === AMBrc decoder power supply === AMBrc unit can be powered by the **power supply** or through the **USB interface**. As ZRound needs the serial port interface you must power the decoder. If you used the USB interface you still need to connect it (or use the device power supply instead).
