dtr DTR Control
This command interprets how the radio modem responds to the state of the
DTR signal and changes to the DTR signal. If the host device (DTE) interface
does not provide a DTR signal then this setting should always be set to off.
When DTR control is set to on and the DTR signal is not active, the Radio
Modem enters a power saving shutdown state. Upon the DTR signal becoming
active, the Radio Modem will power up, perform a reset and be ready to receive
data. The Radio Modem will continue to remain in the powered state while DTR
remains active.
Command format:
dtr [s]
where: s =
on The state of the DTR signal will determine the power-on state of
the radio modem.
off The state of the DTR signal is ignored and the radio modem
remains always on in standby mode.
batmon Battery monitoring
This command enables or disables monitoring of the battery voltage level.
When battery monitoring is enabled, if the battery level falls below a threshold
of approximately 5.75 volts, the modem status indicator will begin to flash
slowly with a 1 second duty cycle.
Regardless of whether battery monitoring is on or off, if the battery voltage
drops to below 5.0V the radio modem will enter a reset state and cease to
function, until the battery is replaced.
Command format:
batmon [s]
where: s =
on The voltage level of the battery is monitored.
off Battery voltage level monitoring is disabled.
ctime Connection Timeout Period
This command sets the period the radio modem stays connected in an always
listening state, prior to entering low power standby mode.
Provided there is no serial data to be sent, the radio modem will delay for the
set period (1 to 60 seconds) before entering the lower power standby mode.
Command format:
ctime [n]
where: n =
[1..60] The duration, in seconds, prior to the radio modem entering the
standby mode.
