Product Name:1 To 1&1 To Multiple RS485 BUS Master-Slave Network Transceiver For Modbus RTU PLC Relay Configuration Software
Packing list:
1/2/5 pcs RT48D02 2.4G RS485 Wireless Transceiver Module
Overview:
RT48D02 is a RS485 Wireless Transparent Data Transmission Module based on 2.4GHz frequency band, using CI24R1 chip.
The module supports basic AT Commands: Baudrate, Parity bit, ID Number, Version Information, Transmit Power, Frequency Band, Acknowledge Mode and other function settings and queries.
When the module is in AT Mode, the user can use the serial port to send AT Commands to set the parameters of the module.
When the module is in transparent data transmission mode, in ACK mode (default), it can be used as a one-to-one transceiver. If it is applied to one-transmit and multiple-receive (master-slave mode), it needs to be changed to NO-ACK mode through AT command
When the CMD port of the AT module is short-circuited, it enters the AT mode. and when it is disconnected, it is the data transparent transmission mode.
When the module is abnormal, short-circuit the two pins of RES on the board for 5 seconds, then power on again to restore the factory settings

Power supply description:
The transmit current is 50mA (+11dBm); the receive current is 25mA, please use a small ripple power supply
Note: In order to make the module work stably, it is recommended to use a power supply above 8W (5V/2A (recommended to reduce the transmit power), 6V/2A, 7.4V/1.5A, 9V/1A, 12V/1A)
AT command:
Please refer to the AT command manual below

Application example:
If it is applied to one-transmit and multiple-receive (master-slave mode), it needs to be changed to NO-ACK mode through AT command.
Please use DC 7-12V power supply, if only 5V power supply, please reduce the transmitting power(AT+POWER=4)
If it is applied to one-transmit and multiple-receive (master-slave mode), it needs to be changed to NO-ACK mode through AT command.
Please use DC 7-12V power supply, if only 5V power supply, please reduce the transmitting power(AT+POWER=4)
