Hi
I have an analyzer of gas that has USB port. So this port works like serial Com Port, and I can communicate with the analizer using a hyperterminal of windows. The analyzer uses one communication protocol to transfer data with commands. When I connect the analyzer to my laptop using a usb cable I see in "device manager" of windows appear a com port "usb serial port Com6" for example.
So I want to connect the analyzer to the CR800 but the only free ports are C1,C2, G. If I use an convert USB to RS232 cable I can get it?. I was thinking use serialopen(), serialIn(), serialout() to transfer commands.
What options can you give me?.
Thank you
Hi,
your analyzer connected to the pc via usb creates a virtual serial connection, thanks to the drivers running on the pc. I guess this is not possible between CR800 and analyzer. Your analyzer has analog outputs or an RS232, RS485 SDI12 or other output. Do you have model and manufacturer? I can see

There probably is a RS232<>USB converter IC built into the Gas analyzer. You'd need to tap into the serial wires there to be able to talk to the analyzer with the CR800..
