Indicator Lights
PORT (#s): Any of the three port activity LEDs will glow
green whenever data is passing through its associated port.
RECON: This LED will flash yellow in response to any
ARCNET reconfiguration event. Repeated flashing of this
LED indicates a fault with cabling or a node device.
STATUS: During boot, this LED flashes green to indicate that
the AI-USB is in standby mode. Once traffic is received on
one of the ARCNET ports and the hub begins to regenerate the
traffic, this LED glows solid to indicate the unit is operational.
USB: This LED glows green so long as a valid active USB
connection exists to an attached computer. This connection is
required before the port 3 LED can turn on.
Electromagnetic Compatibility
All AI-USB units comply with Class A radiated and conducted
emissions as defined by EN55022 and CFR 47, Part 15. This
equipment is intended for use in non-residential areas.
Warning
This is a Class A product as defined in EN55022. In a domestic
environment this product may cause radio interference in which
case the user may be required to take adequate measures.
Field Connections
The AI-USB Series is available in four transceiver options for
connecting to an ARCNET LAN with a particular type of
cable. Each transceiver is identified by a three-character suffix
(CXS, TB5, 485 or 485X) separated from the model number by
a forward slash mark.
The implementation considerations of the various transceiver
options are described in the following pages.
