SET, V+ (power) when boot module into the "setting mode". Not connected
or connected with the GND when boot into "mode of operation".
Module configuration parameters such as Modbus address, baud rate,
parity, communication protocol is composed of module inside the EEPROM
(power down storage device stores). The specific configuration sometimes
forget these parameters that cannot communicate with the module. In order
to prevent this problem, the module has a special mode called "mode".
When the module is based on the "mode" electric start, the module
communicates with the following parameters:
Fixed Modbus address 0
Communication configuration is 9600, N, 8,1 (9600bps, no parity bit, 8 data
bits, a stop bit)
Communication protocol for Modbus-RTU
Configuration parameters in EEPROM will not because the module into the
"mode" and "will change, when the module is in communication with in the
EEPROM configuration parameter is still running mode".
