Quatech, Inc. Confidential
This guide describes the AirborneDirect™ Serial Bridge from Quatech, Inc. AirborneDirect™ is
a fully integrated, 802.11 wireless Local Area Network (LAN) bridge designed to provide
wireless LAN and Internet connectivity in industrial, scientific, medical, and transportation
applications where an existing communications interface already exists. Examples of
applications for which the AirborneDirect™ Serial Bridge is well-suited include:
Point-of-sale devices.
Medical equipment.
Manufacturing machinery.
Bar-code readers.
Time clocks.
Scales.
Data-collection devices.
Vehicle Diagnostics.
Telematics.
The AirborneDirect™ Serial Bridge provides true plug-and-play wireless connectivity right out of
the box, with minimal configuration. It delivers convenient, easy-to-deploy wireless network
connectivity for your productivity and application-critical devices. At the same time, you can
move equipment without the cost and time associated with wired network drops, providing
flexibility for seasonal requirements, line and staffing changes, and more.
The AirborneDirect™ Serial Bridge provides a bridge between the 802.11 wireless LAN and
three leading serial interfaces: RS-232, RS-422, and RS-485. The Bridge acts transparently
between any device using these interfaces and a wireless LAN. Using a virtual communications
port device driver or Dynamic Link Library (DLL), OEMs can communicate with their devices
from any workstation on the same network as if the workstation and devices were directly
attached.
The AirborneDirect™ Serial Bridge opens the world of remote device monitoring and
management, as well as wide-area data collection, to any device, machine, or plant that has an
external serial connection and a network infrastructure. The development kit provides quick and
easy access to the Bridge’s configuration and functions, while providing OEMs with a platform to
develop their branded solutions. The Bridge also provides the capability to perform firmware
upgrades that allow new features to be added quickly and easily, protecting your investment.

SAMPLE APPLICATION
Figure 1 shows a basic application where the AirborneDirect™ Serial Bridge is exchanging data
wirelessly between a serial client and a LAN host. In this application:
The serial client can be a notebook personal computer (PC), or other Data
Terminal Equipment (DTE) whose serial port is directly connected to the
AirborneDirect™ Serial Bridge.
The LAN host can be a PC or PDA running a HyperTerminal or Telnet session,
Web Browser, or LAN-based application. The LAN host communicates with the
AirborneDirect™ Serial Bridge over a wireless network connection via an attached
Access Point or directly in Ad Hoc mode.
Figure 1. Basic Application Involving a LAN Host and Serial Client

Quatech, Inc. Confidential
Figure 2 shows a sample application that uses the AirborneDirect™ Serial Bridge and the
VCOM driver from Quatech. In this application, a customer device (or “serial client”) is an
instrument or data logger that is connected directly to the Bridge and exchanges data wirelessly
with an Access Point. The Access Point is connected to the company LAN. Also connected to
the company LAN is a remote PC (or “LAN host”). The LAN host is running a customer
application that collects data from the serial client and stores it in a database. The VCOM driver
installed on the LAN host allows the collected data to pass to the customer’s application, without
requiring modifications to the PC hardware or software.

Quatech, Inc. Confidential
ITEMS SUPPLIED BY THE USER
The following items, which are not included in the package contents, are also required:
A serial client with at least one serial port. The serial client must be within the
transmit and receive range of the Access Point to be used with the Bridge.
A LAN host running Microsoft®Windows®XP or Windows 2000.
An IEEE 802.11b/g-compliant Access Point with DHCP enabled.
Mounting hardware for the AirborneDirect™ Bridge cradle.
Note:
Other Access Points in the area may interfere with the Bridge’s ability to
associate with your chosen Access Point (the Bridge will try to associate with
the first available “best-quality” AP). If you encounter difficulties with connecting
to your chosen AP, either remove power from these Access Points or move to
an isolated location, and then perform the setup in Figure 1 on page 3.

STANDARD PACKAGE HARDWARE DESCRIPTION
Figure 3 identifies the components on the Bridge in its standard packaging. These components
include:
An external antenna.
A DB9 male DTE connector and cable attached to the Bridge.
A Reset switch and interface selector shunts on the bottom of the Bridge.
Three indicator Light Emitting Diodes (LEDs) on the top of the Bridge.
A mounting cradle.
Figure 3. AirborneDirect™ Serial Bridge Hardware (standard package)
Reset Switch
The bottom of the AirborneDirect™ Bridge provides access to a Reset Switch. The Reset switch
returns all Bridge parameters to their factory default firmware settings. To reset Bridge
parameters, press (and hold) this switch for at least 5 seconds after power is applied to the
Bridge. To protect against accidental resets, the Reset switch is recessed.

Shunts
The bottom of the AirborneDirect™ Bridge provides access to a Reset button and interface
selector shunts & header (see Figure 4).

Interface Selector Shunts
Figure 4 (see page 12) shows the interface selector shunts and header. These configure the
Bridge’s serial interface for RS-232, RS-422, or RS-485, as follows:
RS-485 w/
Termination
RS-232 Power Pin 9,
Cable Sense
1

RS-232
Cable Sense

RS-422 w/
Termination

Figure 5. Interface Selector Shunts
To allow reliable connection through an RS-232, RS-422, or RS-485 interface, set these shunts
appropriately before using the Bridge with your application.
Note:
The interface type selected by the interface selector shunts must match the
Interface Type setting on the Serial Interface Configuration page of the ACC
interface (see page 35). Otherwise, this mismatch prevents data from being
exchanged.

Indicator LEDs
The Bridge has three indicator LEDs for viewing its current status and connections (see Figure
6). These indicators allow for monitoring and troubleshooting of the Bridge. They also indicate
the Bridge’s power-up status, link, connection, and data-activity status. Table 2 (on page 15)
describes the status of the indicator LEDs.
