There are two variants of the iTIM both of which allow you to control the operation and monitor the status of
the dry pumping system through a parallel interface (for example, connected to your process tool).

The serial option of the iTIM contains a serial interface card, which allows the user to control the operation
and to monitor the status of the dry pumping system through a serial interface. The serial interface card uses
RS232 serial communications to communicate with your control equipment (refer to
Section 5 ).For example,
it is possible to connect the iTIM to the serial port of a PC (Personal Computer) on which a suitable SCADA
(Supervisory Control And Data Acquisition program) has been installed.
