E43-433T13S is a super cost-effective wireless data transmission moduleintroduced by Ebyte. It has four working modes and two transmission modes.Various transmission modes have their own characteristics and can be applied tovarious application scenarios.
Wireless modem E43-433T13S is perfectly suited for industrialapplications and is rigorously tested to ensure industrial reliability andbatch consistency.
E43-433T13S supports a maximum transmit power of 13dBm. User can set alower output power to save power. The module operates at 433MHz, with TTL leveloutput and is compatible with the 3.3V IO port voltage.
E43 has the function of dataencryption & compression. The data of the module transmits in the airfeatures randomness. But with the rigorous encryption & decryption, it canmake the date interception pointless. The function of data compression makes itpossible for decreasing transmission time & probability of beinginterference, while improving the reliability & transmission efficiency.
The advantages of theE43-433T13S
Cost-effective, stronganti-interference ability, available for point-to-point transmission andcustomer-defined networking.
Strict power control system,sleep current as low as 1uA, suitable for battery power applications
Supports monitor mode andbroadcast mode,Antenna&Power which adapt to more customer design needs
Supports fixed-point mode, which makes it easyto implement point-to-point, point-to-multiple applications without anyinfluence on each other.
RSSI value isavailable to read, which can detect the signal strength value of the samefrequency band in the environment, and more conducive to the networking mode ofthe customer's custom protocol.
Configurableparameters. Users can change the module configuration information at any timeby using their own devices. And there are two modification modes forconfiguration, one modification mode will save the configuration parametersafter power-off, and the other modification mode will not be saved afterpower-off.
Small size, SMD packing, easy for customerintegration.Two antenna interfaces, oneis a spring antenna and the other is an IPX interface, which is convenient forthe user to choose according to the actual appearance of the product.
Functional analysis of E43-433T13S
Transparent transmission
Transparent transmission is on when module works at mode 0.Transparent transmission is available when the parameters are the same for bothtransmitter and receiver.
Broadcast transmission
Broadcast transmission refers to the wireless module in the samefrequency band and different address, set the transmitter address as 0XFFFF,then all the modules in this frequency band can receive the message sent by themodule with the address 0XFFFF.
Monitoring
Monitoring function refers to the module which address is 0XFFFFcan receive the data from the module with same channel and different addresses.
As shown in the figure, a pair of AB modules with address 0x0010,a pair of CD modules with address 0x0020, and the module with the same channel whichaddress is 0xFFFF can receive communication data of two pairs of modules.(Prerequisite, two pairs of modules cannot do transmitting at the same time)
Fixed-point transmission
The addresses and channels can be random for receiver. And makesure the transmitter and receiver all worked in fixed-point transmission.
The module A address is 0x1010, the channel is 0x17, and the Bmodule sends the data content x11 0x12 0x13 x014 at a fixed point. Then thedata content actually transmitted by B is 0x10 0x10 0x17 0x11 0x12 0x13 x014,and the output content of the module A is x11 0x12 0x13 x014, Only modules withan address of 0x1010 and channel 0x17 can receive.
