7.3.Input/Output

The number and type of I/O on the M4M network analyzer varies according to the different product
versions. Please refer to the "Version" chapter at page X for details.
Input
Each programmable I/O can be configured as Pulse Input or Tariff Input.
Selecting Pulse Input, the device counts detected pulses connected to input port, that should last at least
30ms. It is needed to consecutively set a pulse ratio associated to the pulse counter, and then a unit of
measurement to be associated to the pulses.

Selecting Tariff Input allows to manage the tariffs via inputs. Only I/O1, I/O2 and I/O3 can be used for
Tariff inputs. To use the function is also necessary to set up a corresponding number of Inputs as "Tariff"
source. For more details, please check the Tariffs dedicated chapter at page 32.

Digital Output

Each programmable I/O can be configured as Alarm output, Communication output, Pulse output,
Output ON or Output OFF.
Selecting Alarm output, the output can be associated to a simple alarm or to a complex alarm. Please
note that it is mandatory to set up a single alarm or a complex alarm prior to setting an output as Alarm
output. In case no alarms have been set up, an information pop-up will appear to inform that no alarm is
set, with an hyperlink to the Alarm settings. For alarm settings, please refer to chapter "7.4. Alarms" and
"7.5. Complex alarms".
Selecting Comm. output, the output status is controlled directly via bus.
Selecting Pulse output, the output is set as a pulse generator associated with a measured parameter. It
is needed to consecutively set a measured parameter associated to the pulse output, the pulse ratio and
the pulse length.
