==RS-485 interface==
==RS-232 and RS-485 interfaces==
===RS-232===
RS-232 interface supports full-duplex communication which means the data can be both sent and received at the same time as they use separate transmission lines. When entering Sleep or Deep sleep RS-232 will be powered off.
===RS-485===
RS-485 interface supports only half-duplex communication, which means data is transferred only one way at a time. When activated RS-485 driver chip draws constant 30mA current when entering Sleep or Deep sleep RS-485 will be powered off.
===RS-232 / RS-485 modes===
