Communication with commands through RS-485 

The displays can obtain the displayed parameters through commands, as well as force the display time 
through RS-485 commands. In this case, the display must be configured for not to sync another way or the 
sync will rewrite the programmed time. The frames are sent in ASCII (character) format. The end of block is 
the one defined by user in parameter 9.3 

The following frames can be sent
