The USB-Link™ 2 is a hardware device that enables service bay personal computers

(i.e., PCs and/or laptops) to retrieve vehicle information using either Wi-Fi technology or a more traditional cable connection. Once configured, the USB-Link™ 2 interfaces with your PC, enabling you to use specific PC applications to perform vehicle diagnostics.

This chapter introduces the USB-Link™ 2 and provides details regarding the communication modes available to you to interface with your PC.

The following table outlines the features called out in Figure 2.1.

Feature What It Does

Vehicle Port Connects the USB-Link™ 2 to a vehicle.

Power LED Illuminates when the device receives power.

Data LED Illuminates when the device is receiving data from the vehicle.

Wireless LED Mini Access Point Mode:

• Illuminates solid when a client PC connects to the device.
• Off when not connected. Infrastructure Mode:
• Stays off when not associated with an Access Point.
• Blinks every second when associated with a network but no IP address assigned.
• Illuminates solid when successfully assigned an IP address.

Fault LED Illuminates when a problem is detected.

USB Port Connects the device to your PC (wired connection).

The Reset Button

If you have configured your USB-Link™ 2 device in Infrastructure Mode (using the USB-Link™ 2 Explorer), you can use the Reset button on the bottom of the device to switch from Infrastructure Mode back to Mini Access Point Mode (the factory default). Just push and hold the button until all the lights on the front of the device flash, about five (5) seconds.

NOTE:

i For detailed information on the USB-Link™ 2 Explorer, see Using the USB-Link™ 2 Explorer in Chapter 3 of this manual.

• Communication Options

Communication Options ................................................................

Prior to using the USB-Link™ 2, you need to decide how you want the unit to com- municate with your PC. There are two options:

• A wired connection to the PC using a USB cable (pg. 11) or
• A wireless connection to the PC using Wi-Fi (pg. 12)

Wired Connection

A USB connection provides several advantages. It’s easy to configure; you just plug it in. Also, there’s no confusion about which USB-Link™ 2 is connected to the PC (just follow the cable). Finally, a USB connection is not susceptible to radio fre- quency interference and provides higher communication reliability.

IMPORTANT:

ä ECU reprogramming typically requires both high throughput and critical timing, and should always use a USB-to-PC wired connection.

Wired communication between the USB-Link™ 2 and your PC requires an auto- motive A to Mini-B USB cable (shipped with the USB-Link™ 2).

Figure 2.2 Automotive A to Mini-B USB Cable

NOTE:

i For detailed instructions on making a wired connection, refer to Connect Using a USB Cable , in Chapter 3 of this manual.

• Communication Options

Mini Access Point Mode (Peer-to-Peer)

The easiest and quickest way to connect your USB-Link™ 2 to your PC is Mini Access Point mode. In Mini Access Point mode (also known as Access Point Em- ulation mode), the PC communicates directly with the USB-Link™ 2. The USB- Link™ 2 emulates the function of an access point, allowing the PC to connect directly to the USB-Link™ 2, as if it were an access point. When the PC is con- nected to the USB-Link™ 2 in Mini Access Point mode, neither device is connected to the company network.

Figure 2.3 Mini Access Mode

If you use your PC’s internal wireless network card to connect to your company’s network and the Internet, you may want to obtain an additional wireless network card for use with the USB-Link™ 2. Otherwise when you connect the USB-Link 2 to your PC using Mini Access Point mode, you will not have access to the Internet until you have finished your session and reconnected to your company’s network.

Chapter 2 • Introducing the USB-Link™ 2 Wi-Fi Edition

For instructions on connecting the USB-Link™ 2 and your PC using Mini Access Point Mode, see Connect Using Wi-Fi, in Chapter 3 of this manual.

Infrastructure Mode (Connecting to your Company’s Network)

In Infrastructure mode, your PC communicates with your company computer network through a Wireless Access Point (not included), which acts as a bridge between the wireless network and the wired network. In this mode, the USB- Link™ 2 is configured to communicate with the same access point. All communi- cation between the PC and the USB-Link™ 2 passes through the access point.

Figure 2.4 Infrastructure Mode

NOTE:

i The settings for connecting to your company network may differ from one installation to another. To ensure network security, your Information Tech- nology (IT) administrator will need to oversee the installation and specify the appropriate configuration parameters. Your IT administrator should be able to properly configure the USB-Link™ 2 for infrastructure mode, using the USB-Link™ 2 Explorer utility (see Chapter 3 of this manual).

Chapter 3 • Installing the Drivers and Setting Up the Device
