Chapter 1 The Enpac 2500 Data Collector
POWER / TRIG / USB
This socket connects the Enpac to either an external trigger, power adapter or
USB interface. The external trigger enables synchronization of the data
acquisition process to external events, such as tachometer inputs for rotational
synchronization for balancing applications, or for order normalization of
frequency spectrum. The trigger pulse can also be used to collect running speeds
of machinery. The pin assignment for the trigger is shown in
Pin Assignments on
page 23 .
The external power adapter can be used to charge the internal battery. This can
be connected to the Enpac by connecting the DC output of the mains power
supply to the in line socket of the USB Power Splitter cable (Cat. No. 1441-
PEN25-COMS-US). Then connect the Fischer plug into the Power socket on
top of the Enpac. Only the provided transformer may be used. Any other supply
may cause permanent damage to the data collector.
A USB interface is also provided via the POWER/TRIG connector and the USB
Power Splitter cable. The interface is configured as a Client to allow automatic
connection to a PC through Microsoft ActiveSync™ software. This interface
allows you to copy files and transfer data from the data collector to your PC.
Refer to Installing ActiveSync on page 103 .

RS-232 Interface
Data can also be transferred between the Enpac and your computer over an
RS-232 interface. The RS-232 interface is provided via a 9-way (Plug) D-
connector on the top of the Enpac 2500 data collector. The cable catalog number
is 1441-PEN25-COMS-RS.
