Chapter 1 – Product Description and

Specifications

Introduction

The MultiConnectTM WF device server connects serial devices to an IP network via 802.11b wireless
networking. It enables you to build wireless networking into virtually any device allowing for remote
monitoring, control and configuration. The device server integrates a complete TCP/IP protocol stack.
It can make your existing and next generation device, machine or system, IP-ready while you focus on
developing its core features.

Benefits

• Serial-to-802.11b wireless networking

• Flexible IP protocol stack

• Compact, rugged industrial chassis

General Safety

The MultiConnectTM WF device server is designed and intended to be used in either fixed or mobile
applications. In the “Fixed” application, the device is physically secured at one location and not easily
moved to another location. In the “Mobile” application, the device may be regularly moved to different
locations.

Caution! Maintain a separation distance of at least 20 cm (8 inches) between the transmitter’s

antenna and the body of the user or nearby persons. The adapter is not designed for, nor intended
to be, used in applications within 20 cm (8 inches) of the body of the user. Such uses are strictly
prohibited.

Radio Frequency Interference

Avoid possible radio frequency (RF) interference by carefully following the safety guidelines below.

• Switch OFF the MultiConnect

operation of the aircraft.

• Switch OFF the MultiConnect

before filling a vehicle with fuel.

• Switch OFF the MultiConnect

equipment may be in use.

• Respect restrictions on the use of radio equipment in fuel depots, chemical plants, or where

blasting operations are in progress.

• There may be a hazard associated with the operation of your MultiConnect

the vicinity of inadequately protected personal medical devices such as hearing aids and
pacemakers. Consult the manufacturers of the medical device to determine if it is adequately
protected.

• Operation of theMultiConnect

cause interference if the equipment is inadequately protected. Observe any warning signs and
manufacturers’ recommendations.

Handling Precaution

All devices must be handled with certain precautions to avoid damage due to the accumulation of static
charge. Although input protection circuitry has been incorporated into the devices to minimize the effect of
this static buildup, proper precautions should be taken to avoid exposure to electrostatic discharge during
handling and operation.

Chapter 2 – Installation and Cabling

Attaching the MultiConnect WF to a Fixed
Location

The MultiConnect WF is design to be used on the desktop or to be panel-mounted. To attach the bracket
for panel-mounting, following these steps:

1. Typically, it is mounted against a flat surface with two mounting screws. Drill the mounting holes

at the desired location. The mounting holes must be separated by 4 -15/16 inches center-to­center.

2. To attach the mounting bracket, slide it into the corresponding slot on the back of the

MultiConnect chassis.

3. Attach the adapter to the surface with two screws.

Connection

• Connect a fused DC power cable into the

power connector on the MultiConnect WF
device server.

• Then attach the two wires at the other end of

the fused cable to a DC fuse/terminal block on
a vehicle in which you are mounting the
MultiConnect WF device server.

• Connect the red wire to the "+" positive and

the black wire to the "–" negative. Be sure the
GND connection is correct.

Warning: Over-voltage protection is

provided on the device. To ensure
complete protection, you may want to
add additional filtering to the DC input.

Appendix A – Waste Electrical and Electronic Equipment Statement

Appendix A – Waste Electrical and

Electronic Equipment Statement

WEEE Directive

The WEEE directive places an obligation on EU-based manufacturers, distributors, retailers, and
importers to take-back electronics products at the end of their useful life. A sister Directive, ROHS
(Restriction of Hazardous Substances) complements the WEEE Directive by banning the presence of
specific hazardous substances in the products at the design phase. The WEEE Directive covers all Multi­Tech products imported into the EU as of August 13, 2005. EU-based manufacturers, distributors,
retailers and importers are obliged to finance the costs of recovery from municipal collection points,
reuse, and recycling of specified percentages per the WEEE requirements.

Instructions for Disposal of WEEE by Users in the European Union

The symbol shown below is on the product or on its packaging, which indicates that this product must not
be disposed of with other waste. Instead, it is the user’s responsibility to dispose of their waste equipment
by handing it over to a designated collection point for the recycling of waste electrical and electronic
equipment. The separate collection and recycling of your waste equipment at the time of disposal will help
to conserve natural resources and ensure that it is recycled in a manner that protects human health and
the environment. For more information about where you can drop off your waste equipment for recycling,
please contact your local city office, your household waste disposal service or where you purchased the
product.
