Hardware
RS-485 Communication
Figure 3-19 shows the RS-485 sig-
nals on header J11.
Developing an RS-485
Network
The 2-wire RS-485 serial-commu-
nication port and Dynamic C net-
work software are used to develop
an RS-485 network.
The OP7100 can be linked together
with other Rabbit Semiconductor
controllers over a twisted-pair network for up to 1.2 km. When configuring a
multidrop network, use single twisted-pair wires to connect RS-485+ to RS-
485+ and RS-485- to RS-485- as shown in Figure 3-20.
