Will the CNV100 4-wire to 2-wire converter work with ION meters or Powerlogic meters?

Issue
Will the CNV100 4-wire to 2-wire converter work with ION meters or Powerlogic meters?

Product Line
CNV 100, ION meters, Powerlogic meters

Cause
Customer would like to add 2 wire meter (like ION Meter) at end/begining of 4 wire daisy chain. 

Environment 
Customer wants to install 2 wire communication meter in 4 wire daisy chain. 

Resolution
Yes, the wiring must be as follows:
The + on the ION meter goes to + on the CNV100 and the - on the ION meter will go to the - on the CNV100.

If you are coming from a master the Tx+ of the CNV100 will go to the Rx+ of the master device and the Tx- of the CNV100 will go to the Rx- of the master. The Rx+ of the CNV100 will go to the Tx+ of the master device and the Rx- of the CNV100 will go to the Tx- of the master device.

If you are wiring straight through the Tx+ of the CNV100 will go to the Tx+ of the device and the Tx- of the CNV100 will go to the Tx- of the device. The Rx+ of the CNV100 will go to the Rx+ of the device and the Rx- of the CNV100 will go to the Rx- of the device.

NOTE: Customer can not convert 4 wire daisy chain to 2 wire and back to 4 wire again. Therefore, having 2 CVN100 in one daisy chain will not work. 

Review the CNV 100 documentation for additional diagram on how to wire up the CNV 100 in your application. If you have any additional question, feel free to contact our Technical Support.
