4.1 Dipswitch Selector
To set the dipswitch, unscrew two screws located at the meter front panel and remove the dipswitch cover.
The dipswitch (8 switches) is located on the meter’s front panel. Using these dipswitches you can setup two
functions:
a) Communication mode, and;
b) Connect-disconnect the backup batteries.
Dipswitches position: For the ON position, press the dipswitch downward.
The DRM has one UART (Universal Asynchrony Receive Transmit Port) and one communication RS232 port;
the dipswitch position enables a selection of the communication mode
