D ESCRIPTION
Displays the firmware version.
0 = Enable Point-to-Point Mode (P2P)
1 = Enable Point-To-Multipoint Mode (P2M)
2 = Enable Broadcast Mode
Source address. The range is 0x1 to 0xFFFFFFFD.
0xFFFFFFFE and 0xFFFFFFFF are reserved.
Destination address. The range is 0x1 to 0xFFFFFFFD.
0xFFFFFFFE and 0xFFFFFFFF are reserved.
Change baud rate to 1200, 2400, 4800, 9600, 19200,
38400, 57600, 115200, 230400 bps.
Group ID. The valid range is 0x1 to 0xFE.
Sets the RF channel number for the device. See the
XR18W753 for the valid channel range.
Number of Retries. The range is 0x1 to 0xA.
Power level of RF transmitter. The range is 0x1 to 0x8
Display the current values of the source address, desti-
nation address, baud rate, channel number, etc.
Switch from command mode to data mode.
Switch from data mode to command mode. The time
between each "+" should be between 250ms and 1 sec.
Sets a key for the AES engine
Change the I 2 C address of the RF Transceiver.
0 = Power-up in command mode
1 = Power-up in data mode
0 = Autobaud detect disabled at next power-up
1 = Autobaud detect enabled at next power-up
