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
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.
