SMART-1 and SMART-INTERFACE

Detector Interface Module (DIM) (SMART-1) (SMART-INTERFACE)• An Intelligent High Voltage Supply for HPGe Detectors
• Provides Detector State-of-Health (SOH) Information
• Security Function Allows Use of Authentication Codes
• Rugged Housing to Protect Electronics

The SMART-1 option for ORTEC HPGe detectors is a major enhancement to operational quality assurance and to data and chain-of-custody integrity. It is supported directly through MAESTRO MCA Emulation software which is supplied with the digiDART, digiDART-LF, DSPEC-jr-2.0, DSPEC-LF, DSPEC-Pro, DSPEC-50, and DSPEC-502 digital nuclear multichannel analyzer systems. For other multichannel analyzers, the SMART-INTERFACE provides the same control as the SMART-1. 

The SMART-1 HPGe detector includes the high voltage supply, so an external high voltage power supply is not required. The SMART-1 HPGe detector monitors and reports on vital system functions and the SMART-1 identification serial number can be read by the instrument. For more security it can save authentication codes and report the code at a later time. 

ORTEC SMART-1 HPGe detectors monitor the following conditions:
• Preamplifier +24 and +12 V values (read-only)
• Detector element temperature (read-only)
• Detector high voltage value (read-only)
• Detector high voltage state (on/off)
• Detector overload state (read-only)
• Detector HV shutdown state (read-only)
• Detector serial number (read-only)
• Detector authentication code (read/write)

These parameters are displayed as required on the LCD display of the attached instrument or computer (local or remote).

SMART-1 Physical
The SMART-1 is housed in a rugged ABS molded plastic enclosure. The SMART-1 is permanently attached to the detector endcap via a molded, strain-relieved sealed cable. This eliminates the possibility that the detector will suffer severe damage from moisture leaking into the high voltage connectors. The SMART-1 can be positioned in any convenient place and does not interfere with shielding or other mounting hardware.

    SMART-INTERFACE provides communications between the ORTEC SMART-1 detector and an analog amplifier with any MCA or a Digital Signal ProcessorSMART-INTERFACE allows the SMART-1 detector technology to be used with virtually any MCA — even analog.

    SMART-INTERFACE provides communications between the ORTEC SMART-1 detector and an analog amplifier with any MCA or a Digital Signal Processor that cannot directly connect to the SMART-1. Easy to use software is provided to access the SMART-1 detector's State-of-Health (SOH) data and control the high voltage.

    The SMART-INTERFACE is supplied with one detector output signal cable, one inhibit output signal cable [for use with -PLUS or Transistor Reset Preamplifiers (TRP)], one preamplifier power cable for an ORTEC preamplifier power supply, one preamplifier power cable to connect to another manufacturer’s preamplifier power supply, a USB extension cable for connection to a PC and software to control the high voltage and display the detector SOH data.

    SMART-INTERFACE Software
    To start the SMART-INTERFACE software, click the Window’s Start button, then "ORTEC SMART-INTERFACE." Note, the software is initially minimized to the system tray. To terminate the SMART-INTERFACE software, right click the SMART-INTERFACE icon and click "Shut Down."

    To see the SMART-INTERFACE dialogue box, click the SMART-INTERFACE icon in the system tray.

    SMART-INTERFACE Dialogue Box

    HV On/Set    Turns on the bias voltage to the detector and sets the HV to the target voltage. The user enters the target volts in the "Target" box.
    Actual   Displays the voltage applied to the detector.
    HV Off   Turns off bias voltage to the detector.
    Close   Closes the dialogue box for the SMART-INTERFACE software. Note, this does not cease operations for the SMART-INTERFACE software.
    Clear SOH   Clears the data from the Detector/DIM State-of-Health (SOH) chart and resets the Initial Date/Time to the current date and time.
    Drop-Down Menu (Left)  Selects the COM port that will be used to control the SMART-INTERFACE.  
    Drop-Down Menu (Right) Indicates the bias shutdown logic that is being used. This should always be set to SMART for use with a SMART-1 detector.


    SMART-INTERFACE Controls Menu
    Access the SMART-INTERFACE controls menu by clicking on the upper left corner of the SMART-INTERFACE dialogue box. A drop-down menu will appear.

    SMART-INTERFACE Controls

    Move  Moves the dialogue box. 
    Close (ALT+F4)
    Closes the dialogue box
    Set Recommended HV
    Allows the user to enter a value for the bias (normally the recommended value from the SMART-1 detector QAD sheet).
    Get Recommended HV
    Acquires the value entered by the user in the Set Recommended HV step and applies this value to the "Target" box of the SMART-INTERFACE dialogue box.
    DIM Authentication Code
    Allows the user to change or delete the authentication code.
    User Password
    Opens the Manage User Password dialogue box and allows setting or deleting password protection of the HV On/Off function and provides a means of changing the password. Note, the default password is "ORTEC".

    Setting the HV On/Off is password protected by default. If the "HV On/Off without Password" box is not checked in the Manage User Password dialogue box, the HV On/Off Password dialogue box will appear.
