Maybe I have the wrong group... if so, please excuse me, but here's the
question.
I have a 5-gas vehicle exhaust emissions analyzer with a standard centronics
printer output. When a button on the analyzer's keypad is pressed, the
connected printer prints out information which includes the concentration of
oxygen carbon monoxide, carbon dioxide, hydrocarbonsand nitrogen oxides in
the vehcle's exhaust gas. I would like to hook this printer output to a
laptop's parallel port and read this info with a visual basic pgm I would
write, which would store the values of the gas concentrations (with a
time/date stamp) into a database or spreadsheet-compatible file. Assuming I
can find out the data stream (variables, byte lengths of variables, etc.)
from the analyzer's printer port, should this be a problem? Would I need a
regular DB-25 to DB-25 cable or should it be a null modem type of cable
(like a laplink parallel cable)?
thanks anyone!
