Anyone have an example of the rs485 data on the wire? (is it msb/lsb, ...) Does the capture below look ok?
I connected an EKM Omnimeter II UL v.3 to an RS485 gateway, but I can't get the meter to response. (it's 9600 baud, 7 data bits, even parity)

Re: rs485 data
Hello randy,
Thanks for posting to the forum!
The very best place to start would be to read your meter with the EKM Dash and go to Help > Hex Inspector to see the RS485 Hex data. This will both confirm that you have the meter connected correctly and will act as a tool to teach you how we parse the data.
The next thing I would do would be to go to the bottom of this page: http://www.ekmmetering.com/developer-portal
Here we have both the RS485 string parsing document and the settings protocol. Between these you can get most of the way to reading your meter (the remaining tricky bit is how to calculate CRC16).
From your screenshot it looks like you are trying to request data from meter 000010001025, is this the correct meter number? This is a full meter request without a meter response. The full set of serial settings are: 9600 baud, even parity, 7 data bits, 1 stop bit and no flow control.
Good luck! Please let us know if you have any questions

Re: rs485 data
I fixed it. Issue was on RS485 gateway. Thanks.
