3.3.4. RS-485 Connection
The RS-485 network requires a 120Ω termination resistor at both the host end (EM100) and at the
furthest point in the network. The EM100 has a software selectable terminator built-in (see ‘STR’
command).
Note: For half-duplex (RS-485) operation tie RS-485 TX+ with RS-485 RX+ and RS-485 TX- with
RS-485 RX-.
