APPENDIX A: INSTALLING FTDI DRIVERS FOR WINDOWS
Before using the RN-ISP to download firmware or configure the RN-131 or RN-171 module using their respective
development boards (RN-134 or RN-174), you must first install FTDI drivers. You can download the drivers from the FTDI
website at http://www.ftdichip.com/Drivers/VCP.htm. After you download the drivers perform these steps to configure the
COM ports:
1. Run the FTDI driver executable to install it.
2. When the driver finishes installing, connect the RN-ISP to the USB port of your computer.
3. Open your PC’s device manager. You will see four USB serial converter devices: A, B, C, and D as shown in
