+JTAG protocol communication is a very vulnerable protocol, please avoid interference.
20
+
21
+- From JTAG connector to target IC layout please follow the high frequency signal requirement.
22
+- Make sure the PC end of USB balster can supply sufficient power, no interference and no any other USB device use together.
23
+- Eliminate the interference source, such like cell phone, and shorten your USB cable
24
+- if any communication error happened, reconnect the programmer, and restart Quartus II software.

40
+Note about distance:
41
+
42
+If the distance required for far, can be connected to the 1/4 wavelength of the antenna, generally use 50 ohm single conductor, the length of the antenna 315M of about 23cm, 433M of about 17cm;
43
+
44
+The position of the antenna has also affected the reception of the module, install the antenna as straight as possible away from the shield, high pressure, and interference sources;
