Product Overview
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
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.

6Product 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
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.
Device Compatibility
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
TIP You cannot connect the 1761-HHP-B30 Hand-held Programmer
to the AIC+ advanced interface converter.

information.
Wire the Power Supply
Power Supply
ATTENTION EXPLOSION HAZARD —
An external power supply must be used in Class I, Division 2
applications and the dc power-source selector switch must be
in the EXTERNAL position before connecting the power supply
to the AIC+ interface converter.
IMPORTANT In nonhazardous locations, external power is not required if the
AIC+ interface converter 8-pin mini-DIN com port is connected
to a MicroLogix controller.
IMPORTANT Some devices provide power to the AIC+ interface converter via
the 8-pin mini-DIN com port cable. The dc power-source
selector switch needs to be set for your particular
configuration.
If you are using a 1746-P1 or 1746-P2 power supply, the AIC+
interface converter is the only device that can be connected to
that power supply.
Always connect the CHS GND (chassis ground) terminal to the
nearest earth ground. This connection must be made whether
or not an external 24V dc supply is used.
