6.4.10 DL: Set or Query the Command Delay Interval
$<listenerID>,DL<delay>*<checksum><cr><lf>
$<listenerID>,DL?*<checksum><cr><lf>
$<talkerID>,DL=<delay>*<checksum><cr><lf>
(delay interval, in 50ms increments) (Factory Default Setting = 01)
Example 1
Set the command delay interval to 250ms and verify the new setting.
Use the DL command to set the delay interval from when the sensor receives a command to
when the command is executed. The DL command is primarily intended for use where a time
delay may be required to allow the RS485 interface to switch from transmit to receive mode.
For example, if the delay interval is set to 250ms then the sensor will commence outputting
the wind velocity data between 250-300ms after receiving a WV query command.
If any further commands are sent to the sensor before the delay interval has elapsed they will
be discarded.
