− | RS-485 supports only Half Duplex communication. It means that at one time data is only sent/received.<br/>When activated RS-485 driver chip draws constant 30mA current.<br/>When Entering Sleep or Deep sleep, Chip will be powered off too.<br/>FMB125 RS-485 Pins connection diagram are shown on the Figure 66: | + | RS-485 supports only half-duplex communication, which means data is transferred only one way at a time.<br/>When activated RS-485 driver chip draws constant 30mA current, when entering Sleep or Deep sleep, RS-485 will be powered off.<br/>FMB125 RS-485 connection diagram is shown below: |
