Hi ,
I am trying to communicate between L&T single phase energy meter. I am using single phase two wire AC Watthour meter and manufactured by Larsen & Turbo .. Model no EM101+
The protocol used for communication is RS232I need to know the commands to retrieve parameters like voltage,current,power etc. from energy meter that I can send from hyperterminal.
I can't find a datasheet of the meter to identify the RX,TX
Thanking you in advance for your kind help.Click image for larger version.
