Product Overview
Description
The AIC+ advanced interface converter provides a communication
link between various networked devices. Ports 1, 2, and 3 are used
for making the communication connections. The AIC+ is
compatible with a variety of SLC and MicroLogix controllers
and peripherals.
MicroLogix controllers provide power to the AIC+ via port 2’s
cable. However, if a MicroLogix controller is not connected to port
2, 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 on pages 3–1 through 3–9 for more details on how to wire
and configure the AIC+.
The baud rate selector switch is used to match the baud rate filter of
the AIC+ to the network baud rate. This switch does not change the
network baud rate and is normally left in the AUTO position. In
high noise environments, the baud rate selector switch should be
taken out of the AUTO mode and set to the same baud rate as the
network. See Auto Transmit Delay on page A–2 for more
information on baud rates.

Operating Modes
The AIC+ can be used in the following modes:
• point-to-point isolator (see page 3–1)
• RS-232 to RS-485 isolator (see pages 3–2 through 3–8)
• RS-232 to half-duplex “user mode” ASCII isolator
(see page 3–8)
Communication is established using hardware handshaking or auto
transmit signals. For more information on hardware handshaking,
see page A–1. For more information on auto transmitting, see page
A–2.

Important:
Some devices provide power to the AIC+ via port 2’s

to be set for your particular configuration.
If you are using a 1746-P1 or 1746-P2 power supply,
the AIC+ 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.

Grounding and Terminating the RS-485 Network
Only one connector at the end of the link must have Terminals 1 and
2 jumpered together. This provides an earth ground connection for
the shield of the communication cable.
Both ends of the network must have Terminals 5 and 6 jumpered
together. This connects the termination impedance (of 120Ω) that is
built into each AIC and AIC+ as required by the RS-485
specification.

DH-485 Connector
➀ An 8-pin mini DIN connector is used for making connections to port 2. This connector is not
commercially available. If you are making a cable to connect to port 2, you must configure your
cable to connect to the Allen-Bradley cable shown above.

Hardware Handshaking.J
To implement hardware handshaking, use cables that support the
following signals.
Signal Definition
Function
RTS active
an input to AIC+ port
CTS active
an output from AIC+ port
When hardware handshaking is used, the auto transmit delay
(turnaround time) is zero.

➀ Any communication coming off of the RS-485 line (port 3) will not drive the handshaking lines on
ports 1 and 2. Devices on ports 1 and 2 can drive the other RS-232 ports handshaking lines and
the RS-485 transmitters.

Auto Transmit Delay is measured from the time the AIC+ transmits
its last mark out of Port 3, until the delay time (from table above)
expires. The AIC+ will not accept Port 3 data during the Auto
