read data from 9 pin RS232 serial port
read data from 9 pin RS232 serial port
(OP)
I need to read data from the 9 pin RS232 serial port on a gas analyzer into a PC. I dont have any info on the format, speed or protocol of the data.
I have heard about Winwedge but this project is currently in the experimental stages so I dont want to buy commercial software yet.
Is there any trial/ shareware versions of this Winwedge or oher similar Data acquisition software?

Note that most such systems require some sort of initialization command to get stuff going, so you'll need to do some work to get that if needed.

I found Hyperterminal a bit too cumbersome and bloated to use for simple RS232-to-RS232 tasks. It also seemed to be not that reliable.
I use Tera Term as a Windoze replacement for Telix or Telemate

Development seems to have ended at v2.3 (well, it does what it should, so thats ok)
And yes it can certainly be done in VB and even VBA. A co-worker is regularly using VB to implement a RS485 protocol to connect to a TSI flowmeter.
If there is any other program available that can communicate with the gas analyzer, you could use a serial port spy like this one

to figure out the trigger sequences or the protocol. (You'd probably be thrown in jail afterwards because of DMCA violation :)

Windows PC: Listen32

Pocket PC: PocketDAQ

Both allow for ASCII and BINARY interrogation.

and in the subject write: RS-232 program
As soon as I can I will send you the program

You need their "box" to interface the date to the "sniffer" PC.
Works great, does just about any RS232 protocol, speed etc.
I think the last box i bought was about $1300.
