Connecting the AIC+

Note Only Series C or later MicroLogix 1000 discrete controllers and all MicroLogix
1000 analog controllers support DH-485 connections with the AIC+.
You can connect an unpowered AIC+, catalog number 1761-NET-AIC, to the
network without disrupting network activity. In addition, if a MicroLogix 1000
controller powers an AIC+ that is connected to the network, network activity will
not be disrupted should the MicroLogix 1000 controller be removed from the AIC+.
The figure that follows shows the external wiring connections and specifications of
the AIC+.
