Manual Revision History 

 

Rev A   

 

New manual 

Rev B   

 

Added User Oscillator 

Rev C (01/31/2008) 

Added a section about supported baud rates. 

 

 

 

Added a diagram of the User Oscillator. 

 

 

 

Added information about COM port numbering in Windows. 

 

 

 

Added section on COM port enumeration for application developers. 

Rev D (08/13/2008) 

- Added the IDAN-CM17320 Dimensions and Pinout section, which 

 

 

 

  replaces the (previously separate) IDAN Manual, IDM-650020032. 

 

 

 

- Corrected the IDAN connector pinout, which was listed incorrectly 

 

 

 

  in IDM-650020032 rev A. 

 

 

 

- Added information about RTD pre-installed User Oscillators 

 

 

 

- Expanded the board block diagram to clarify the oscillator operation 

 

 

 

- Renamed the jumper designations for the signal conditioning jumpers. 

 

 

 

  They now use the designations printed on the board silk, rather than the 

 

 

 

  JPxx designation from the schematic. 

 

 

 

- Improved the Connector and Jumper Locations diagram. 

 

 

 

- Changed the name of the RS-422/485 Transmitter control section to 

 

 

 

  more accurately indicate its purpose. 

Rev E (8/17/2009) 

- Added spec for External clock input 

- Added second mode jumper to get RS-422 with drivers always enabled 

and  RS-485  with  inverted  RTS  driver  enable  modes  in  addition  to  RS-

232  and  RS-422/485  (now  just  RS-485  mode)  with  RTS  driver  enable 

modes
