XStream‐PKG‐T™TelephoneRFModem–ProductManualv5.x00[2006.02.24]
MD (RF Mode) Command
AT Command: ATMD
Binary Command: 0x32 (50 decimal)
Parameter Range: 0 – 2
Parameter Configuration
0 Peer-to-Peer (Transparent)
1 Multi-Stream Base
2 Multi-Stream Remote
3 Repeater
4 Repeater End Node
Default Parameter Value: 0
Number of bytes returned: 1
Related Commands: CB (Connection Duration
Timeout), CE (Connection Inactivity Timeout),
CM (Connection Message), DC (Disconnect)
Minimum Firmware Version Required: 4.30
<Networking & Security> The MD command is
used to select/read the setting that enables
Multi-Stream and Repeater Modes.
Multi-Streaming Mode enables exclusive
connections in point-to-multipoint networks.
Refer to the Multi-Streaming Mode section [p
34]
for more information regarding how these
parameter values affect other parameter values.
Repeater Mode enables longer range via an
intermediary modem. When MD=3, the modem
will act as a “store and forward” repeater. Any
packets not addressed to this node will be
repeated. A Repeater End Node (MD=4) handles
repeated messages, but will not forward the data
over-the-air. Refer to the Repeater Mode section
[p
29] for more information.
MK (Address Mask) Command
AT Command: ATMK
Binary Command: 0x12 (18 decimal)
Parameter Range: 0 – 0xFFFF
<Networking> MK Command is used to set/read
the address mask. All data packets contain the
Destination Address (ATDT) of the transmitting
module. When an RF data packet is received, the
transmitter DT Address is logically “ANDed”
(bitwise) with the Address Mask (ATMK) of the
receiver. The resulting value must match the
Destination Address or the Address Mask of the
receiver for the packet to be received and sent
out the module’s DO serial port. If the “ANDed”
value does not match the DT Address or the MT
Address of the receiver, the packet is discarded.
Default Parameter Value: 0xFFFF
(Destination address (DT parameter) of the
transmitting module must exactly match the
destination address of the receiving module.)
Number of bytes returned: 2
Related Commands: DT (Destination Address),
HP (Hopping Channel), ID (Modem VID), MY
(Source Address)
MY (Source Address) Command
AT Command: ATMY
Binary Command: 0x2A (42 decimal)
Parameter Range: 0 – 0xFFFF
Default Parameter Value: 0xFFFF (Disabled -
DT 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)
Minimum Firmware Version Required: 4.30
<Networking> Set/Read the source address of
the module.
