Contemporary Controls USB22 Series User manual

USB22 Series
ARCNET®Network Interface Modules with USB Interface
INSTALLATION GUIDE
INTRODUCTION
The USB22 Series of ARCNET Network Interface Modules (NIMs)
links Universal Serial Bus (USB) computers with the ARCNET Local
Area Network (LAN). USB has become popular for connecting desktop
or laptop computers to peripherals because of its very high-speed interface
(up to 480 Mbps) and its convenience of a powered exterior interface with
no need to open the computer.
Each USB22 includes a COM20022 ARCNET controller that can
support data rates up to 10 Mbps and a microcontroller to transfer data
between the ARCNET and either USB 2.0 or USB 1.1 devices. The NIM
is powered from a computer USB port or a USB hub. Models exist for the
most popular ARCNET physical layers. A USB cable is also provided.
NOTE: The USB22 Series of NIMs are for users who are willing and
able to modify their application-layer software. Some OEM companies
have modified their software to work with the USB22. If your
application is not provided by one of these companies, you cannot use
the USB22 —unless you rewrite your application software or hire a
software engineer to do it. (See the SOFTWARE section of this
installation guide for information about the Software Developer Kit.)
If USB22-compliant software is provided by your OEM and you
encounter installation difficulties, you should contact your OEM for
resolution of your issue —because Contemporary Controls has no
knowledge of the OEM software.

ELECTROMAGNETIC COMPATIBILITY
All USB22 models 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.

INSTALLATION
SOFTWARE
When a USB cable first connects the NIM to a PC and you are prompted
for a driver, follow the instructions that appear when you click on the
Software Developer Kit link at the following URL:
www.ccontrols.com/support/usb22.htm
INDICATOR LIGHTS
ARCNET: This will flash green in response to any ARCNET activity.
USB: This LED glows green so long as a valid active USB
connection exists to an attached computer.
FIELD CONNECTIONS
The USB22 is available in four models that vary by transceiver type for
connecting to an ARCNET LAN via a certain kind of cable. Each model’s
transceiver is identified by the suffix (-4000, -485, -CXB or -TB5)
separated from the main number by a hyphen.
-CXB Coaxial Bus
Generally two types of coaxial cables are used with ARCNET:RG-62/u
and RG-59/u. RG-62/u is recommended because it matches the 93-ohm
-CXB impedance and can thus achieve the maximum 1000-foot segment
distance. Although RG-59/u does not match the -CXB impedance (it is
75-ohm cable), it will still work, but the segment length may be limited.
Never attach coax cable directly to the USB22-CXB; always use the
provided BNC “T” connector. The “T” connector allows the coaxial bus
to continue as shown with device A in Figure 4. Apply the provided
93-ohm BNC terminator to the “T” if the USB22 terminates the coax in
an end-of-line situation as shown with device B in Figure 4.

-TB5 Twisted-pair Bus
The -TB5 transceiver accommodates twisted-pair cabling via a pair of
RJ-45 jacks which allow the unit to be daisy-chained at any location on
the bus segment. Usually IBM type 3 unshielded twisted-pair cable
(UTP) is used, but shielded cable (STP) can also be used to provide
continuous shielding between devices.
When the USB22-TB5 is located at the end of a bus segment, apply the
provided 100-ohm terminator to the empty RJ-45 jack to match the
cable impedance.
-485 DC-Coupled EIA-485
Two models support DC-coupled EIA-485 segments. The USB22-485
provides dual RJ-45 jacks and the USB22-485/S3 offers a 3-pin screw
terminal. Each segment can be up to 900 feet of IBM type 3 (or better)
STP or UTP cable while supporting up to 17 nodes. Make sure the phase
integrity of the wiring remains consistent throughout the network. All
phase A signals on NIMs and hubs must connect together. The same
applies to phase B. Refer to Figures 1 and 2for connector wiring.
Termination
If the NIM is located at the end of a segment, apply 100 ohms of
termination. For the USB22-485, insert a terminator in its empty RJ-45
jack. For the USB22-485/S3, attach a resistor to its 3-pin connector.
Bias
Bias must also be applied to the network to prevent the differential
receivers from assuming invalid logic states when the signal line is
floated. Bias is provided on the USB22-485 by a set of 806-ohm pull-up
and pull-down resistors.
Ground
All devices on the segment should be referenced to the same ground
potential to achieve the common mode voltage (+/–7 Vdc) required for
the EIA-485 specification. A ground connection is not provided by the
NIM. It is assumed adequate grounding is supplied by the existing
equipment. Refer to the existing equipment user manual for a discussion
of grounding requirements.

-4000 AC-Coupled EIA-485
The AC-coupled EIA-485 transceiver offers advantages over the
DC-coupled version. No bias adjustments are needed and wiring polarity
is unimportant. Much higher common mode voltage levels can be
achieved with AC coupling because the transformer coupling has a
breakdown rating of 1000 VDC.
However, AC-coupling also has disadvantages. AC-coupled segments
are shorter (700 feet max) and are limited to 13 nodes compared to 17 for
DC-coupling. Also, AC-coupled transceivers operate only at 1.25, 2.5,
5.0 and 10 Mbps, whereas DC-coupled transceivers function over all
standard data rates.
Two models support AC-coupled EIA-485 segments. The USB22-4000
provides dual RJ-45 jacks, whereas the USB22-4000/S3 offers a 3-pin
screw terminal.
Cabling rules are similar to those for DC-coupled NIMs. Wire nodes in a
daisy-chain fashion. Refer to Figures 1 and 2for connector pin
assignments. Termination should only be applied to devices located at
the two ends of the segment. Do not mix AC-coupled and DC-coupled
devices on the same segment; however, bridging the two technologies is
possible with active hubs that have appropriate transceivers.
