Transmit power levelMode 1.3mW 5mW 25mW 100mWE34-DTU（2G4H20) √ √ √ √★ Note: The lower the transmit power, the closer the transmission distance, but the working current won’t be declined inexact proportion, it is recommended to use the maximu m transmit power.5.5. Current parametersModel Transmitting current mA Standby current mA12V 24V 12V 24VE34-DTU（2G4H20) 143 86 25.5 32★ Note: It is recommended to retain more than 50% o f the current marg in when selecting the power supply, which w illhelp the data transceiver to work steadily for a long time.5.6. Transceiver Length and Sub-packing ModeModel Buffer Sub-packageE34-DTU（2G4H20) 256Byte Automatic subcontracting of 27 bytes to send★ Note:1. When the receiving data is more than a single packet capacity, the beyond part will be automat ically assignedto the second transmission until it is completed;2. The data transceiver cannot receive data which is more than the buffer capacity;6. Operating modeE34-DTU(2G4H20) has four operating modes , if low power consumption is not required, normal co mmunication isrecommended to configure the data transceiver for the normal mode (mode 0);The factory default is normal mode (mode 0).Categories M1 M0 DescriptionM ode 0 Normal M ode ON ON Open UART and RF，transparent transmission is onM ode 1 Wake-up M ode ON OFF Air wake-up mode, the packet comes with a wake-up code,M ode 2 Power-saving M ode OFF ON The air wake-up receive mode, saving receive power, the mode can notbe transmittedM ode 3 Sleep M ode OFF OFF Parameter setting using the configuration software
