Command
Name and Description
Parameter
Range
Default
AP API Enable. Enable API Mode.
0 = Transparent
mode
1 = API-enabled
2 = API-enabled
(w/escaped control
characters)
1
AO
API Output Options. Indicates the type of frame to output when data is received on
the IP services port
0=ZigBee Rx
1=Explicit Zigbee Rx
2=RX64
2 (RX64)
BD
Interface Data Rate. Set/Read the serial interface data rate for communication
between the module serial port and host. Any value above 0x0A will be interpreted
as an actual baud rate. When a value above 0x0A is sent, the closest interface data
rate represented by the number is stored in the BD register.
1 - 7
(standard baud
rates)
1 = 2400 bps
2 = 4800
3 = 9600
4 = 19200
5 = 38400
6 = 57600
7 = 115200
8 = 230400
9 = 460,800
0xA = 921,600
0X5B9 - 0X5B8D80
(non-standard rates
up to 6 Mbps)
3
NB Serial Parity. Set/Read the serial parity setting on the module.
0 = No parity
1 = Even parity
2 = Odd parity
0
SB
Stop Bits. Set/read the number of stop bits for the UART. (Two stop bits are not
supported if mark parity is enabled.)
0 = 1 stop bit
1 = 2 stop bits
0
RO
Packetization Timeout. Set/Read number of character times of inter-character
silence required before packetization. Set (RO=0) to transmit characters as they
arrive instead of buffering them into one RF packet . Regardless of how small RO is,
the inter-character silence required to trigger a transmission of the data is 100 usec.
0 - 0xFF
[x character times]
3
FT Flow Control Threshold. De-assert CTS when FT bytes are in the UART receive buffer 0x11 – 0x823 0x7F3
D7 DIO7 Configuration. Select/Read options for the DIO7 line of the RF module.
0 = Disabled
1 = CTS Flow
Control
3 = Digital input
4 = Digital output,
low
5 = Digital output,
high
6 = RS-485 transmit
enable (low enable)
7 = RS-485 transmit
enable (high enable)
1
D6 DIO6 Configuration. Configure options for the DIO6 line of the RF module.
0 = Disabled
1 = RTS flow control
3 = Digital input
4 = Digital output,
low
5 = Digital output,
high
0
