USB_ADC I/O Module 
   USB_ADC

      The USB_ADC I/O module is designed to interface with
      the Northern Scientific NS-62x series of ADCs and
      the Tracor-Northern TN-12xx series of ADCs.  The
      ADCs are precision devices having from 10-bits to 13-bits of
      pulse-height resolution. The 10-bit devices have a 0 to 4 volt
      input conversion range and the 13-bit devices have a 0 to 8 volt
      input conversion range.

USB_TMR I/O Module 
   USB_TMR

         The USB_TMR I/O module is generally used in a multi-parameter
      configuration to provide a time stamp for the event.  The
      module has a 13-bit counter (it counts from 0 to 8191 then
      repeats) and is programmable to increment at intervals from
      100 microseconds to 10 seconds.  The intervals are 100, 200,
      and 500 microseconds, 1, 2, 5, 10, 20, 50, 100, 200, and 500
      milliseconds, and 1, 2, 5, and 10 seconds.  The 13-bit
      counter thus has a timing interval of .8192 seconds for
      the 100 microsecond configuration to 81,920 seconds for
      the 10 second configuration.

NS-62x and TN-12xx Cable Pinouts 
         The NS-62x series and TN-12xx series of ADCs use different
      types of interface connectors.  The Ns-62x series use the
      26M AMP type connectors.  The TN-12xx series of ADCs use the
      standard DB-37 connector with a slide latch. 

      The following reference provides details on the NS-62x and
      TN-12xx connector pinouts and the IDC ribbon cable pinouts.

Making Cables For The NS-62x and TN-12xx ADCs 

          The TN-12xx series of ADCs use the standard DB-37 connector
      with a slide latch.  The parts required to construct a cable to
      connect the TN-12xx ADC to the USB_ADC I/O module are referenced
      here (any equivalent part may be used):




          The NS-62x series series of ADCs use the 26M AMP type connectors.
      The connector shells are currently available, however, the small
      diameter machined pins are NOT.  One can create an equivalent plug
      for these ADCs by fabricating a PC board with the correct pin layout
      and soldering equivalently dimensioned pins to the PC board.  The
      PC board layout and parts required to construct a cable to connect
      the NS-62x ADC to the USB_ADC I/O module are referenced here:
