ForceDiscoverRegister - a write to this register, typically using a broadcasted Set Remote Register command, will force a
heartbeat reply if a device's parent has the specified base-mode network ID (or 0xFF wildcard), and the least significant
byte of the device’s MAC address is within a specified min/max range. The payload consists of 3 bytes: NWKID (NN),
minimum MAC address (LL), and maximum MAC address (XX). In Little Endian hexadecimal format this would appear as
“XXLLNN”.
DiagPortEn - setting this parameter to 0x01 enables diagnostic port operation.
7.5 Protocol-formatted Message Examples
7.5.1 Data Message
In this example, the ASCII text
“Hello” is sent from the base to a remote using the TxData command.
The MAC address of the remote is 0x123456. The protocol formatting for the host message is:
SOP Length PktType Lo MAC MAC Hi MAC “H” “e” “l” “l” “o”
0xFB 0x09 0x05 0x56 0x34 0x12 0x48 0x65 0x6C 0x6C 0x6F
There are 9 bytes following the length byte, so the length byte is set to 0x09. Note that the 0x123456 network address is
entered in Little-Endian byte order, 56 34 12. When an ACK to this message is received from the remote, the base out-
puts a
TxDataReply message to its host:
SOP Length PktType Lo MAC MAC Hi MAC Status RSSI
0xFB 0x07 0x15 0x56 0x34 0x12 0x00 0xB0
The 0x00
TxStatus byte value indicates the ACK reception from the remote. The RSSI value of the received ACK is 0xB0,
indicating a received signal strength of approximately -80 dBm .
The ASCII
“Hello” message is output at the remote as a 0x26 RxData event. The address field contains the originator’s
address, 0x00 0x00 0x00, which is the base. The RSSI value of the received message is 0xB4, indicating a received sig-
nal strength of approximately -76 dBm. The data following the RSSI value is the “Hello” text.
SOP Length PktType Lo MAC MAC Hi MAC RSSI “H” “e” “l” “l” “o”
0xFB 0x0A 0x26 0x00 0x00 0x00 0x35 0x48 0x65 0x6C 0x6C 0x6F
Note that if the remote was in transparent mode, only the
“Hello” text would be output.
7.5.2 Configuration Messages
In this example, the remote with MAC address 0x123456 is configured by the base (MAC address 0x000000) to generate
RxEvent messages every 10 seconds. To do this, the IoReportInterval in the remote is set to 10 seconds and the periodic
report timer bit in the IoReportTrigger parameter is set ON. The IoReportInterval and the IoReportTrigger parameters are
loaded using SetRemoteRegister commands. The command to set the IoReportInterval to 10 seconds is:
SOP Length PktType Lo MAC MAC Hi MAC Reg Bank Size Lo Val Val Val Hi Val
0xFB 0x0B 0x07 0x56 0x34 0x12 0x1C 0x06 0x04 0x10 0x27 0x00 0x00
