Sensus water meter

I have been trying to read a sensus water meter with a ECR connection. From poking around on the Net I know that the ECR uses a synchronous transfer of 7 bit ascii with 1 stop bit even parity.

the meter should reply with the following Data frame

V;RBxxxxxxxx;IBLOT030115<CR>
where the xx'xs is the reading on the odometer.

I have been using a 500hz clock on the RED wire to the ECR and sampling the Green wire for the data Black is common. At this point I am getting no response from the meter. I am wondering if anyone might have some timing information that might point me in direction of what I am doing wrong. T goal is to install the meter on the cold water side of the water heater to get flow and total usage.
