Hi Sir,
I'm using HPL LT-CT Meter, TYPE: CT 05, -/5A and trying to connect the RS232 with the converter to read the values using GXDLMSDirector.

I've tried using Indian Standard, keeping all the settings as default, set serial with baud 9600 but couldn't make the meter connect to the software/

ERR: Failed to receive reply from the device in given time.

I've even changed the baud to 300,19200 etc but no response.

Could you help me with the communication of the meter with the software..
Thanks

Your Previous Reply:
Problem is usually in the cable. If you have USB to serial converter you can't use other converters after that. Try to get a converter that you can use to connect directly to the meter.

Hi Sir,
The attachment shows the connection from the meter to converter to the desktop.

Hi,

We just read HPL meter. Check that your wires are right connected. Can you try to get ready-made cable? It might help.

Hi Sir,

I was able to connect to the HPL meter. The problem was the RS232 port of the meter needed external 5V (VCC) to be connected in order to communicate with the device.

Hi Sir,

I am unable to get the data, however i can see the in meter right corner the rx/tx is happening from keyboard or if trying read from application.

I connected the TX, RX, GND, and 3.3V from USB-TTL converter.

also is USB-TTL converter is correct to read data?
