COMUNICATION PROTOCOL INSTRUCTION
This module can communicate with computer,so that the current and voltage reading can be displayed by the computer.
Because the output of this module is a TTL level,inorde to communicate with computer, thid=s level signal has to be transfered to a RS232 level which can recognize by the computer, this module(eBay item number:321254713986)is used to do this job.
