HP E1432-61602 Voltage-type Break Out Box

In this type of Break Out Box the signal is sent straight through to the
sub-miniature "D" connectors on the HP E1432A/33A.
HP E1432-61600 ICP-type Break Out Box
Each of the eight connectors in this type of Break Out Box is connected to
an independent, floating current source. These are intended to power
integrated-circuit piezo-electric (ICP) transducers. They supply 4.5 mA
(nominal) at up to 28 volts. The current sources are controllable by
software in groups of four. That is, the current sources for connectors 1-4
can be turned on or off as a group, as can the current sources for
connectors 5-8.
Break Out Box Grounding
Each connector on the HP E1432-61600 and HP E1432-61602 Break Out
Box has a small manual switch next to it. When this switch is in the
"GND" position the outer shell of the connector is grounded to the chassis
ground of the VXI mainframe. When it is in the "DIFF" position it is not
grounded to the mainframe and will float if not grounded elsewhere in the
system (such as at the sensor). The connector shell should not be allowed
to float: if the switch is in the "DIFF" position the shell should be
grounded elsewhere in the system.
