External Connections
The external hardware connections for communications and data collection are
located on the top panel of the Enpac 2500, as illustrated in this figure.

CH1 / CH2 Inputs
Signal inputs are made through the LEMO connectors marked CH1 and CH2
on the top of the Enpac.
The maximum measurement range is ±40 V while the minimum full-scale range
voltage available is ±10 mV (peak). The inputs are protected against high voltage
transients, but sustained over-voltage input levels must be avoided. Voltage can be
DC or AC coupled, while the third option, Accel (ICP), is available for direct
connection of integrated circuit piezoelectric transducers. These settings are
specified in the Emonitor software.
