XStream™OEMRFModule–ProductManualv5.x00[2006.02.24]
MY (Source Address) Command
AT Command: ATMY
Binary Command: 0x2A (42 decimal)
Parameter Range: 0 – 0xFFFF
Default Parameter Value: 0xFFFF (Disabled –
the DT (Destination Address) parameter serves
as both source and destination address.)
Number of bytes returned: 2
Related Commands: DT (Destination Address),
HP (Hopping Channel), ID (Modem VID), MK
(Address Mask), AM (Auto-set MY)
Minimum Firmware Version Required: 4.30
<Networking & Security> Set/Read the source
address of the module.
Refer to the Addressing section [p
36] of the RF
Communication Modes chapter for more
information.
NB (Parity) Command
AT Command: ATNB
Binary Command: 0x23 (35 decimal)
Parameter Range: 0 – 5
Parameter Configuration
0
8-bit (no parity or
7-bit (any parity)
1 8-bit even
2 8-bit odd
3 8-bit mark
4 8-bit space
5 9-bit
Default Parameter Value: 0
Number of bytes returned: 1
Minimum Firmware Version Required: 4.30
(previous versions did not support the 9
th
bit.
<Serial Interfacing> Select/Read parity settings
for UART communications.
PC (Power-up Mode) Command
AT Command: ATPC
Binary Command: 0x1E (30 decimal)
Parameter Range: 0 – 1
Parameter Configuration
0 Power-up to Idle Mode
1
Power-up to
AT Command Mode
Default Parameter Value: 0
Number of bytes returned: 1
Minimum Firmware Version Required: 4.22
<Command Mode Options> PC Command allows
the module to power-up directly into AT
Command Mode from reset or power-on. If PC
Command is enabled with SM Parameter set to 1,
DI3 (pin 2) can be used to enter the module into
AT Command Mode. When the DI3 pin is de-
asserted (low), the module will wake-up in AT
Command Mode. This behavior allows module
DTR emulation.
PK (RF Packet Size) Command
©2006MaxStream,Inc.ConfidentialandProprietary 28
<Serial Interfacing> Set/Read the maximum size
of the RF packets sent out a transmitting
module. The maximum packet size can be used
along with the RB and RO parameters to
implicitly set the channel dwell time.
Changes to this parameter may have a
secondary effect on the RB (Packet Control
Characters) parameter. RB must always be less
than or equal to PK. If PK is changed to a value
less than the current value of RB, RB is automatically lowered to be equal to PK.
AT Command: ATPK
Binary Command: 0x29 (41 decimal)
Parameter Range: 0 – 0x100 [Bytes]
Default Parameter Value: 0x40 (64 decimal)
Number of bytes returned: 2
Related Commands: RB (Packetization
Threshold), RO (Packetization Timeout)
Minimum Firmware Version Required: 4.30
