Using the pass-through
connectors for
custom accessories
By connecting custom cables that use the pins on the pass-through
connectors, you can provide power and communication or other
signals for your custom accessories. The power and signals pass
through the spectrometer from the front to the sample compartment
and vice versa. Make sure your use of the connectors complies with
the voltage and current limitations given in the following Warning.
Warning
Improper or unsafe cabling can cause damage to your accessory and
may create a safety hazard. Only qualified persons should cable a
custom accessory using these connectors. Do not pass signals that
exceed ±15 VDC through these connectors. You must also limit the
current to a maximum of 800 mA. Thermo Electron is not
responsible for damage or injury resulting from improper or unsafe
cabling.

The following diagram shows schematically which pins of the
Auxiliary
connector inside the sample compartment are connected
internally
to pins of the
Auxiliary 1
and
Auxiliary 2
connectors on
the front of the spectrometer. Since none of these connected pins are
assigned by the Nicolet 4700 or Nicolet 6700, they are available for
use with custom accessories.
