Is any special software needed on the DAQ machine to record the data?
No. Any terminal emulation should work and we have tested it with the free MS HyperTerminal or older MS Terminal programs supplied with MS Windows Operating Systems. The data is ASCII and semi colon delimited so it can easily be imported into MS Excel or similar programs for analysis or viewed as is by the user. There is optional software, the LMNView software, which allows you to connect locally or remotely over a network (intranet) and easily view the data according to date time using a tree structure. This plots the data and shows you spectrum information on particle types as well as fixed field information on performance of the unit. However if you are well versed in MSExcel you can easily import the same information and plot it from the ASCII files with some work. The LMNView software is not mandatory and if you are on a tight budget it can be added if so desired at a later date.
