Andover Controls Infinet ii i2 Infilink 200 Communication Unit
Introduction
The Andover Continuum Infinet II (i2) Infilink 200 is an electronic repeater and a 5-port active hub for Andover’s Continuum Infinet field bus, designed to transmit RS-485 signals beyond the 31-device/4,000-foot (1.2 km) limitation.
Andover Continuum Infinet II Infilink 200 Communications Unit Features
Product AT A GLANCE
- Five-Port Active Hub for Andover Continuum Infinet Field Bus
- Extends RS-485 Field Bus Communications Beyond the 31 Device/4,000 Feet (1.2 km) Standard Limitation
- AC and DC Models Available
- RS-485 to RS-232 Conversion for Short-Haul Modems
- Detachable RS-485 Connectors Provide Easy Installation
- Switch Selectable Baud Rates, from 300 to 57.6K Baud
- AC Input Voltage Switch- Selectable
- Full LED Indication for Easy Troubleshooting
Andover’s Continuum Infinet field bus can be comprised of both Andover
Continuum Infinet and Andover Infinet II controllers
The i2200 accepts twisted pair cabling at each of its five RS-485 ports. A
single Andover Continuum Infinet RS-485 input supplies up to four RS-485
output signals, or “spokes.” Each spoke has the drive capability of up to
4,000 feet (1.2 km) and up to 57.6K baud with up to 31 separate devices
attached.
For conversion applications, when existing phone lines are in place, the same
RS-485 input can become a single RS-232 output for use with thirdparty short
haul modems. (The four RS-485 output ports are still available when using the
RS-232 port.) Data transmission speeds for the i2200 are switch-selectable
from 300 to 57.6K baud.
The i2200 simplifies network troubleshooting by using LED indicators. These
LEDs flash to indicate when the i2 is receiving and transmitting RS-232 and
RS-485 signals.
Enclosure
The i2200 is provided with a hinged, black 16- gauge, cold-rolled steel
enclosure. Installation is simplified by the use of detachable connectors for
all RS-485 ports.
AC and DC Models Available
The i2200 is available in two models: The AC model is powered from a standard 115/230 VAC source. A 24 VDC model is also available for applications where battery-backed operation is required.
- Note: Only data rates up to 19.2K baud are presently supported on the Andover Continuum Infinet network.
