Shutter circuitry which allows an electrically isolated logic signal to control the
voltage between the Photocathode and MCP In. This allows long gate times or CW
operation.
Operation
 
Review the Danger and Warning notices on page 6 before operating the IIC-200.
 
Set the IIC-200 Power switch to 
OFF
 and wait 5 minutes.
The high voltage cable should be handled with care. Dropping the cable, banging the
connectors, twisting the wires or applying excessive force when tightening may damage
the pins, resulting in a poor or intermittent connection.
Connections with a Gen II Intensifier
 
 Connect one end of the high-voltage cable supplied by Roper Scientific to the high-
voltage connector on the image intensifier. If you have purchased more than one
image intensifier, make sure you are using the cable supplied with that particular
intensifier. The connectors are keyed and must be properly oriented. Push the cable
connector into the receptacle and continue to turn the threaded ring clockwise until it
is tight (10 inch-lbs maximum torque).
Note: 
Two versions of the 6-pin high voltage cable have been shipped by Roper
Scientific. Early high-voltage cables have a white housing. Later ones have a black
housing and a white stripe. These cables are wired differently. The IIC-200 is
compatible with the newer style cables only. For more information, see The High
Voltage Cable
 on page 13.
 
Connect the opposite end of the cable to the high-voltage output connector of the
IIC-200 using the same procedure.
Gated Operation
 
For gating, set the 
Shutter/Gate
 switch to 
Gate
.
 
Connect a cable from the output of the pulser to the 
Gate In
 BNC connector. For
Gen II units, the mating connector must be a BNC type.
Shutter Mode Operation
 
For shuttering, set the 
Shutter/Gate
 switch to 
Shutter
.
 
Connect a BNC cable to the IIC-200 
Shutter In
 BNC connector. Connect the other
end to the Controller’s TTL SHUTTER OUT BNC connector (may also be named
SHUTTER or SHUTTER MONITOR, depending on the controller model) .
Unlike Princeton Instruments integrated ICCD detectors, in Shutter mode operation, if
the Shutter In BNC on the IIC-200 is allowed to float, the intensifier will be On
Continuously
. Overexposing the image intensifier at any time when the intensifier is
turned on can result in permanent damage to the image intensifier.
