Note
:

When the Countdown Timer expires (reach 0) it will stop automatically (SW 0).

If two or more Timers expire at the same timer, Timer with smaller id has higher priority, i.e. Command String related
to that Timer will be executed first.

These are not precision Timers, if the Modem is busy (e.g. with network communication). The execution time may
be delayed.

20.4.2 Input Port operation mechanism
The Input Port will give out a high or low signal depending on the input connection to the port (see 13.1)
The Command String can check the change of Input port Signal (operation “DR”):
IP 1 DR 0  detect a low-to-high input voltage change
IP 1 DR 1  detect a high-to-low input voltage change
