Specification :

size:83x51x37mm Host mode setting method: 1, the module does not power on, the shorted HOST-ended GND (11and 12 ). 2, connected to power, power to the module, the module that is to enter the host mode, will continue to press the issue of Modbus protocol data read register commands. 3, note that to enter the master mode, CONFIG do not shorted to ground pin (GND pin), otherwise they will enter the default mode.
