Connecting the AIC+
You can connect a MicroLogix 1100 controller to a DH-485 network via
Channel 0 directly without using an optical isolator, such as AIC+, catalog
number 1761-NET-AIC, because Channel 0 is isolated. However, you need to
use an AIC+ to connect your PC or other MicroLogix Family products, such
as MicroLogix 1200, to a DH-485 network.
The following figure shows the external wiring connections and specifications
of the AIC+.
For additional information on connecting the AIC+, refer to the Advanced
Interface Converter (AIC+) User Manual, publication 1761-UM00.
