Networking and Security : Set/read the channel number (Uses
802.15.4 channel numbers). The range is 0xC to 0x17.
ID
– PAN ID
: Set the PAN (Personal Area Network) ID. Use 0xFFFF to
send message to all PAN's. The range is 0x0 to 0xFFFF.
DH
– Destination Address High
: Set/read the upper 32 bits of the 64
bit destination address. Set the DH register to zero and DL less than
0xFFFF to transmit using a 16 bit address. 0x000000000000FFFF is the
broadcast address for the PAN. The range is 0x0 to 0xFFFFFFFF.
DL
– Destination Address Low
: Set/read the lower 32 bits of the 64 bit
destination address. Set the DH register to zero and DL less than
0xFFFF to transmit using a 16 bit address. 0x000000000000FFFF is
the broadcast address for the PAN. The range is 0x0 to 0xFFFFFFFF
MY
– 16 Bit Source Address
: Set/read the 16 bit source address for
the modem. Set MY = 0xFFFF to disable reception of packets with 16
bit addresses. 64 bit source address is the serial number and is always
enabled. The range is 0x0 to 0xFFFF.
RM
– Random Delay Slots
: Set/Read the minimum value of the back-
off exponent in the CSMA-CA algorithm that is used for collision
avoidance. If RN=0, collision avoidance is disabled during the first
iteration of the algorithm (802.15.4 - macMinBE). The range is 0x0 to
0x3.
MM
– Mack Code
: Set/Read MAC Mode value. MAC Mode
enables/disables the use of a the header in the 802.15.4 RF packet.
When Mode 0 is enabled (MM=0), duplicate packet detection is enabled
as well as certain AT commands. Modes 1 and 2 are strict 802.15.4
modes. This is a pull down option. Selections are:
0
– 802.15.4 + MaxStream
®
Header
1
– 802.15.4 No ACKS‟s
2
– 802.15.4 With ACK‟s
CE
– Coordinator Enable
: Set/Read the coordinator setting. This is a
pull down option. Selections are:
0 - End Device
1 - Coordinator.
SC
– Scan Channels
: Read/set list of channels to scan for Active and
Energy Scans as bitfield. Scans may be initiated by ATAS, ATED
commands and during End Device Association and Coordinator startup:
Bit 15 - Ch. 0x1A . . . Bit 0 -Ch. 0x0B (bits 15, 14 and 0 not available on
ZLinx). The range is 0x0 to 0xFFFF.
SD
– Scan Duration
: Set read the Scan duration exponent. The
exponent configures the duration of the active scan during association.
Set End Device SD = BE of beaconing coordinator. Scan Time = N* (2
^ SD) * 15.36ms. N=# channels: ZLinx = 16, ZLinx/Pro = 13. The range
is 0x0 to 0x0F.
