LPM [1, 0]
Low-Power Mode—Masters Only
This feature trades increased latency to gain power savings. Low-power
mode (LPM) automatically saves power at a Remote by instructing the
Remote to shutdown for large periods of time in between
SYNC
messages.
Master transmissions are automatically blocked while the Remotes are
asleep. Note, both Masters and Remotes are adaptive and will suppress a
normal sleep interval if data transmission or reception is in progress.
•
LPM 1
at the Master enables low-power mode network-wide; all
Remotes pick it up and start saving power by automatically sleeping.
LPM 1
can work in conjunction with the AT dialing feature. The dialed
unit will be forced awake; all others will sleep.
