Description
Description
<Sleep (Low Power)> LH Command
adjusts the duration of time for which
the RF initializer is sent.
When receiving modules are put into
Cyclic Sleep Mode, they power-down
after a period of inactivity [specified by
ST (Time before Sleep) Command] and
will periodically awaken 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 receiver is operating in
Cyclic Sleep Mode. This lengthens
the Wake-up Initializer to a specific
amount of time (in tenths of a second).
The Wake-up Initializer Time must be
longer than the cyclic sleep time that is
determined by SM (Sleep Mode)
Command. 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 3.1 & 3.2
of the SM Command description to view
diagrams of correct and incorrect
configurations. The images help
visualize the importance that the value
of LH be greater than the value of SM.
<Networking> MK Command is used to
set/read the Address Mask.
All data packets contain the Destination
Address of the transmitting module.
When an RF data packet is received, the
transmitter’s Destination Address is
logically “ANDed” (bitwise) with the
Address Mask 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 either the
Destination Address or the Address
Mask of the receiver, the packet is
discarded. (All “0” values are treated as
“irrelevant” values and are ignored.)
