RS232 Programming/Steps Example Desired

Hi Mary,
Thank you very much for the reply. Answers to your questions/comments are:

  1. I’m currently using a SNAP-SCM-232 Serial Module plugged into the rack.

  2. I’ll make transmit string chart (like you did) and try that out.

  3. I’ll fiddle with a receive chart as you suggest also. That will get me some experience with working with OPTO 22 string commands.

  4. I would greatly appreciate an OPTO22 example of parsing the data assuming a EOM character.

  5. I had not gotten to the point of even looking to see what the incoming data looks like. I’m still at the “Programming RS232 on the OPTO22 for Dummies” level. The final result of my work will be to create an automated battery cycling machine. The OPTO22 system will command/control a Chroma Battery Load (RS232 controlled), Sorenson Power supply (RS232 controlled) and associated battery contactors along with voltage/amperage sensing.
