Product Overview
Chapter
1
Description
The AIC+ advanced interface converter provides a communication
link between various networked devices. The AIC+ interface converter
is compatible with a variety of SLC and MicroLogix controllers and
peripherals.
Communication Port and Switch Locations
RS-485
Communication Port
(Phoenix Plug)
Communication-rate
Selector Switch
RS-232 (DB-9, DTE)
Communication Port
RS-232 (8-pin mini-DIN)
Communication Port
DC Power-source
Selector Switch
Terminals for external 24V dc power
supply and chassis ground.
MicroLogix 1000, 1200, and 1500 controllers provide power to the
AIC+ interface converter via the RS-232 8-pin mini-DIN port’s cable.
However, if a MicroLogix controller is not connected to this port, a
24V dc power supply connected to the converter’s external power
terminals is required. The dc power-source selector switch needs to
be set for your particular configuration.
See Network Diagrams starting on page 21 for more details on how to
wire and configure the AIC+ interface converter.
5 Publication 1761-UM004B-EN-P - June 2006
6 Product Overview
The communication-rate selector switch is used to match the
communication rate filter of the AIC+ interface converter to the
network communication rate. This switch does not change the
network communication rate and is normally left in the AUTO
position. In high noise environments, the communication-rate selector
switch should be taken out of the AUTO mode and set to the same
communication rate as the network.
See Auto Transmit Delay on page 35 for more information on
communication rates.
Operation Modes
Device Compatibility
The AIC+ interface converter can be used in the following modes.
• Point-to-point isolator
• RS-232 to RS-485 isolator
• RS-232 to half-duplex user mode ASCII isolator
Communication is established using hardware handshaking or auto
transmit signals.
The AIC+ interface converter can be used to interconnect the
following devices.
• SLC 500, 5/01, 5/02, and 5/03 processors (channel 1)
• SLC 5/03, 5/04, and 5/05 processors (channel 0)
• MicroLogix controllers
• Logix controllers
• 1756-DH485 ControlLogix module
• Operator interface devices
• Personal computer serial ports (or any 9-pin DTE serial port)
• Modems

You cannot connect the 1761-HHP-B30 Hand-held Programmer
to the AIC+ advanced interface converter.
