I cannot get the iSerial to communicate with OmniPulse v4
Posted: Sun May 26, 2013 1:58 am
The problem seems to be one of persistent non-communication. Error shown in the Dash software: "No response – Check RS485 connections and Meter Number"
I have tried just about everything:
1.) Connection made with only a very short twisted pair cable
2.) With and without separate ground wire
3.) Using terminal 2, 3 and 4 for RS485- wire on the iSerial
4.) Different communication settings in the iSerial: 7 and 8 character bits, 1200 and 9600 baut
5.) Tried to discover the Meter Number (as explained in this forum) - no luck, so using the engraved number shown on the meter.
6.) Verification of proper communication from computer to iSerial: When I change e.g. the port number under TCP in the iSerial from 5000 to anything else, the error message changes so I am pretty sure that the iSerial is talking correctly to my computer.
Appreciate any suggestions you may have!
With regards, Piet
