• LPM 0 at the Master to disable low-power mode (Default setting).
The
SLEEP command must be enabled for LPM to function. Further, when
you enable LPM, the LEDs on the Remote radio dim even though the LPM
function is not properly enabled by turning on
SLEEP. For more information,
see “Low-Power Mode (LPM)—Master Enabled” on Page 27, and
“Low-Power Mode versus Remote’s Sleep Mode” on Page 29.
LPMHOLD [0–1000]
Low-Power Mode Sleep Time
Used to give an RTU time (0-1000 ms) to respond before the radio goes to
sleep. Value determines how long to suppress auto-sleep following reception
of the last character sent out of the RXD serial data port.
NOTE: Any values entered will be rounded to the nearest multiple of 4 ms.
To verify the exact hold time, enter LPMHOLD, the response will give you
the value currently being used.
MODE [M, R, X]
Radio Operating Mode
The MODE command sets or displays the operating mode of the radio. A
Master radio is set by MODE M; a Remote set by MODE R, and an Extension
is set by
MODE X.
All units default to Remotes; other modes must be specifically programmed
with the
MODE command.
If
MODE X is used, the MODE X radio should be programmed with an
Extended Address (XADDR). Units that need to hear this MODE X radio must
be programmed with an appropriate
XPRI and/or XMAP value.
MRSSI [NONE, –40...–90]
Minimum RSSI for Mobile Operation
The MRSSI command sets or displays the minimum RSSI level (dBm) of a
Master station’s signal to maintain synchronization. When the Master’s
signal falls below this level, the Remote will attempt to resynchronize with
the next Master it can hear within the same network—same Network Address
(
ADDR)—and, meets the MRSSI level. See “Mobile Operation Support” on
Page 29 for additional information.
OT [ON, OFF]
Output Trigger
The “output trigger” feature sets up a 1-second default delay on delivery of
RXD serial data, however, a receipt of RTS causes cancellation of timer
followed by immediate data delivery.
Hierarchy Rules:
•if
OT = ON, RTS always cancels data delay and outputs immediately
