1.2 General Description
Four types of iTIM are available (refer to Figures 1 and 2):
z 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).
z 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.
Note: All information sent to or received from the iTIM, except from the emergency stop connections, (Whether
serial or parallel data) is software derived.
