MD (RF Mode) Command
MK (Address Mask) Command
from a module without a key, but the output will be meaningless. Because CBC mode is utilized,
repetitive data appears differently in different transmissions due to the randomly-generated IV.
NOTE: For international (non-U.S.) variants of XTend modules, the encryption key is 128-bit AES.
The command operates the same except the key length is 16 bytes rather than 32 bytes. This per-
tains to part numbers ending with -NA or -128 (the -NA and -128 suffix mean the same thing), no
matter what firmware version is loaded. This also pertains to the Australia version of firmware
22xx, no matter what part number XTend it is loaded onto.
<Sleep (Low Power)> The LH Command is used
to set/read the duration of time during which the
wake-up initializer is sent. When receiving mod-
ules are in Cyclic Sleep Mode, they power-down
after a period of inactivity (as specified by the ST
parameter) and will periodically wake and listen
for transmitted data. In order for the receiving
modules to remain awake, they must detect
~35ms of the wake-up initializer.
LH Command must be used whenever a receiving
module is operating in Cyclic Sleep Mode. The
Wake-up Initializer Time must be longer than the cyclic sleep time that [as determined by SM
(Sleep Mode) parameter]. If the wake-up initializer time were less than the Cyclic Sleep interval,
the connection would be at risk of missing the wake-up initializer transmission.
Refer to figures loated under the SM command description to view diagrams of correct and incor-
rect configurations. The images emphasize that the LH value must be greater than the SM value.
<Networking & Security> The MD command is
used to select/read the settings that enable the
Polling and Repeater Modes on the module.
Polling Mode - A ‘Polling Base’ is responsible for
polling remotes. A ‘Polling Remote’ requires a poll
in order to transmit.
Repeater Mode - A ‘Repeater’ re-sends RF data
unless the transmission is addressed to it or if the
transmission has already been detected. A
‘Repeater End Node’ handles repeated messages,
but will not repeat the message over-the-air.
Refer to the Polling and Repeater Mode sections of
the ‘RF Communication Modes’ chapter for more
information.
<Networking & Security> The MK command is
used to set/read the Address Mask of a module.
All RF data packets contain the Destination
Address of the TX (transmitting) module. When a
packet is received, the TX module Destination
Address is logically "ANDed" (bitwise) with the
Address Mask of the RX (receiving) module. The
resulting value must match the Destination
Address or Address Mask of the RX module for the
