REAR PANEL DESCRIPTION
Shown in Figure 2 is the rear view of the Model 133.
Figure 2 Item 1, is the standard AC input power connector. The supplied Endevco power cable,
PN EW599, is connected to this connector. (Note: The acceptable input power is 90 to 264 VAC,
50/60 Hz. No jumpers or adjustment is required for input voltages within this range. There is no
on/off power switch for the unit. )
Figure 2 Item 2, is the Single-Ended Piezoelectric (SEPE) input connector. This is a standard 10-
32 connector, mating to Endevco's 3090 and 3060 series cables.
Figure 2 Item 3, is a blocked-off area for a single channel, depicted is channel 3. The channels
correspond to the front panel channels 1, 2, and 3.
Figure 2 Item 4, is a standard BNC cable connection that is used to connect the input of ISOTRON
or voltage type accelerometers. (10-32 connector style input cables can easily be used with the
Endevco EJ21, a 10-32 to BNC adapter. The EJ21 mounts directly onto the BNC connector.)
Figure 2 Item 5, is a standard BNC connector used for the output from each channel.
Figure 2 Item 6, is the RJ-11 Modular Jack, Front View. (Please see Figures 5, 6 and Section
2.4.7. for the RS-232 information.)
