6.3.7.- Unit configuration variables
The following functions are implemented for these variables:
function 0x04: reading registers.
function 0x10: Writing multiple registers.
NB: The programming values must be written in hexadecimal.
It is necessary to change the screen when a setup change is made for communi-
cations in order for the changes take effect in the display.
6�3�7�1�- Date and time
These parameters occupy 1 register each.
