You will need to have at least one free serial COM port available on the logger for every 5 ShapeArrays (SAAs) that you want to read with an SAA232-5 and for every single ShapeArray that you want to read with an SAA232. The easiest way to add code for reading ShapeArrays is to use the SAACR_FileGenerator utility in SAASuite to generate a CR logger program that just reads SAA data. Then merge this program together with your existing CR logger program for reading other sensors (see Integrating Non-ShapeArray Sensors into ShapeArray Logger Programs).

If you require assistance doing this, please contact Measurand and attach the two programs that you would like to merge with a brief description of what your logger application is supposed to do.
