KEY
Turn On Radio Transmitter Test Signal
Enables the transmitter. (Radio must be in Setup mode.) See also DKEY
command (DKEYDetails, page 44).
LED [ON, OFF]
Enable/Disable PCB LEDs
LED ON enables/disables the PCB board mounted LEDs seen only with the
transceiver’s covers removed.
LED is normally OFF, it may be useful to have
them on for testing the radio with the covers removed. Note: the external
LEDs will be dimmer if the
LED function is left ON.
The
LED command also affects the operation of the LEDs in the “Low-Power
Mode” (
LPM). When LED is OFF, the radio keeps the PWR and SYNC LEDs
extinguished.
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.
