E34-2G4D20D User manualCopyright ©2012–2018, Chengdu Ebyte Electronic Technology Co.,Ltd. 107.4 Reset instructionInstruction format DescriptionC4+C4+C4In setting mode（M0=1，M1=1）,User gives the module instruction (HEX format): C4 C4 C4, the module resets for one time.During the reset process, the module will conduct self-check, AUX outputs low level. After resetcompleting, the AUX outputs high level, then the module starts to work regularly which the workingmode can be switched or be given another instruction.7.5 Parameter setting instructionNo. Item Description Remark0 HEADFix 0xC0 or 0xC2, it means this frame data is control command Must be 0xC0 or 0xC2C0: Save the parameters when power-offC2: Do not save the parameters whenpower-off1 ADDH High address byte of module （the default 00H） 00H-FFH2 ADDL Low address byte of module （the default 00H） 00H-FFH3 SPED7 6 UART parity bit UART mode can be different betweencommunication parties0 0 8N1（Default）0 1 8O11 0 8E11 1 8N1（equal to 00）5 4 3 TTL Serial port rate（bps） UART baud rate can be differentbetween communication parties The UART baud rate has nothing to dowith wireless transmission parameters& won’t affect the wireless transmit /receive features.0 0 0 Serial port baud rate 12000 0 1 Serial port baud rate 24000 1 0 Serial port baud rate 48000 1 1 Serial port baud rate 9600（Default）1 0 0 Serial port baud rate 192001 0 1 Serial port baud rate 384001 1 0 Serial port baud rate 576001 1 1 Serial port baud rate 1152002 1 0 Reserved 0 (recommended)4 CHANGeneral model7、6、5、4 reserved 0 (recommended)communication channel 00H-1FH,16 channels in total;Corresponds to 2400MHz+CHAN * 7MHz3、2、1、0 ,default00H（2400MHz）5 OPTION7 Reserved 0(recommended)6 IO Drive mode（Default 1） This bit is used to the module internalpull-up resistor.
