Rate parameters, including serial speed and air speed
7,6: serial port check bit
00:8 N1 (default)
01:8 O1
10:8 E1
11:8 N1 (equivalent to 00)
---------------------------------------------
5,4,3 TTL serial port rate (BPS)
000: serial port baud rate is 1200
001: serial port baud rate is 2400
010: serial port baud rate is 4800
011: serial port baud rate is 9600 (default)
100: the serial port baud rate is 19200
101: the serial port baud rate is 38,400
110: serial port baud rate is 57600

---------------------------------------------
2,1,0 wireless air rate (BPS)
000: reserved
001: air speed 2k
010: air speed 5k
011: air speed is 8k (default)
100: Reserved

110: air speed is 20k
111: Reserved
 通信双方串口模式可以不同
The serial port modes of
communication parties can be
different
-------------------------------------
 The baud rates of the two
communicating parties can be
different
 The serial port baud rate has
nothing to do with the wireless
transmission parameters and
does not affect the wireless
transceiver characteristics.
-------------------------------------
The lower the air speed, the farther
the distance, the stronger the
anti-interference performance and
the longer the transmission time.
Both sides of the communication air
wireless transmission rate must be
the same

CHAN
Network group no. 00-07h
000: group 0
001: group 1 (default)
010: group 2
011: group 3
100: group 4
Group 5:101
Group 110: group 6
111: group 7
---------------------------------------------
Address of slave machine 00-1eh (default 0)
 No network with the same
number can exist in the same
region
 Devices on different networks
cannot communicate
 Only one host can exist in the
same network
-------------------------------------
 Support 31 slave Numbers
 No slave with duplicate
Numbers in the same network
 This parameter is not valid for
the host

OPTION
7 Reserved
---------------------------------------------
6 IO driver mode (default 1)
1: TXD, AUX push pull output, RXD pull
input
0: TXD, AUX open output, RXD open input
---------------------------------------------
5,4,3 WOR wireless wake up time (for the receiver, is
the listening interval; For the transmitter, it's the time it
takes to keep firing the wakeup codes.)
000：0ms
001：250ms
010：500ms
011：750ms
100：1000ms （Default）
101：1250ms
110：1500ms
-------------------------------------
 This bit is used to enable the
pull-up resistance inside the
module. The drain open circuit
level is more adaptable, but in
some cases external pull-up
resistance may be required
----------------------------------
 The wake up time set by the
host module cannot be less
than the listening interval from
the module, otherwise the data
may be lost
 The longer the wake-up time,
the lower the average
receiving current.
 The host module also
recommends setting the same
WOR time to wake up the
slave.
