L&T ER300P - RS232 Communication cable (PL2303)

General discussion

I am using a PL2303 based USB to RS232 converter which has 4 wire (TX, RX, GND, VCC).

I have connected RJ11 (4 pin) connector as per the meter ER300P datasheet.

I am yet to test this cable with the meter, wanted to confirm if this will work as I don't have access to the meter and need to test the cable in the field.

Any help on this is highly appreciated.

Hi,

There are no big differences between RJ11 cables. Optical probes are a different story.
The only thing you need to check is that the USB driver works with your PC. Some (cheap) USB dongles don't support Windows 11.

Mikko
