- USB type A port (X8) to connect a
flash drive (Firmware, system files
upload/download or data logging).
- The Ethernet connection is made
through a standard RJ45 connector,
the 2 green LEDs in the Ethernet
connector show the port status and
the communication traffic.

In the drawing are connected the
counter inputs as an example
(CNT1 and CNT2).
Frequency meter input:
- The channels can manage up to
10 kHz signals having a duty-cycle
that guarantees minimum of
ON/OFF signal of 20
m
s;
Impulse counter input:
- The minimum time of an impluse
must be 20
m
s;
Digital input:
- The input circuit is internally closed
to the System negative (-) pole
(connector
