Hi guys-Thanks very much for the replies. From following this, I now have transmission abilities, and am seeing the sent messages on the meter via M49. I am having some issues receiving responses now; I have a 10k pull up between VCC and RX1 (pin19) per Chuck's recommendation, but there is basically no reply from the meter. I'm not sure if this is because of a hardware issue, or not sending the right ASCII/RTU codes to the meter. I've tried both ASCII and RTU settings in M63 using the example text on page 40 of the manual. Have also tried different variations of this; changing the formatting, unit #, ect. I've also read that this might need to be converted to hex before sending, but that doesn't seem to make sense to me.
Additionally, under the ASCII selection, there is a sub-menu for "Compatible Protocol", which has 15 options including CRL-G, SCL-61D, SCL-6, SCL-7X, ect. The unit seems to default to SCL-61D.
Any ideas? Thanks again!
If you can either upload the reference guide or provide a link, we might be able to decode the instructions. Without it, I've done everything I know.
Chuck.
