What is the function of the level adapter board

The level adapter board SU108 series is a small board that converts the level of different voltage interfaces to the level of the USB interface. It is one of the products developed by Shenzhen NiceRF Wireless. So what is the function of this level adapter board and what are the working modes?

The role of SU108 series level adapter board

There are three models of SU108 series level adapter board: SU108-485, SU108-232, SU108-TTL. Their function is to convert the 485, 232, and TTL levels to the USB interface level. It is convenient to connect the wireless data transmission module and the PC through the level conversion board, so as to configure the parameters of the module and send and receive data. And other functions.

Working mode of SU108 series level adapter board

The SU108 series level adapter board has a short circuit point, which can be divided into two working modes when it is connected to the digital transmission module.

Note: Connect the short-circuit cap to short-circuit and enter the configuration mode; unplug the short-circuit cap to disconnect and enter the communication mode.

1. Short-circuit: SET is grounded. At this time, the module is in parameter configuration mode and no longer sends or receives data.
2. Disconnect: SET is suspended, and the module is in normal data sending and receiving mode.

The above is the function of the level adapter board SU108 series and its working mode. The SU108 series is a data transmission module configuration/communication board. If you purchase more than 2 wireless data transmission modules from our company, you can give a SU108 series level adapter board. , It is convenient to configure software parameters.
