1) The antenna

Antenna is the important components of the communications system, and the performance will have a direct impact of the communication systems indicators, Module requires the antenna impedance is 50 ohms. In order for the module is in optimal working order, we recommend the use of our company’s standard antenna.

2) Configure boards

Modules need to be followed by PC parameter configuration, data transfer, and other applications (via a jumper selection), our company has the module matching the USB access port and TTL/RS 232 level transfer small panel (via a jumper selection) to allow the users quickly and easily communicate with PC.
