2. Connect power to the CarDAQ-Plus. Verify that the Ethernet Link LED (on the upper right of the

Ethernet port) is on. Wait for the front panel LEDs to stop scrolling.

3. Verify that the green ‘Power' light on the front panel is on.

4. Finally, turn on the PC. If the computer is already on, reboot.

5. On the PC, start a web browser and enter http://192.168.43.101/

in the location bar.

If the CarDAQ-Plus 'About' page is not displayed, see the Troubleshooting Guide. Common problems:

• Your computer's network card should be set to "Obtain an IP address

automatically". For step-by-step instructions to set your computer to

be a DHCP client, see Appendix B: Instructions for configuring your

network card.

• Your web browser should not be using a web proxy.

• Some personal firewall programs may need to be disabled or

configured to allow access to the CarDAQ-Plus.

Direct-connect with manual network configuration

Using manual network configuration (Fixed IP Addressing) requires a little work up front, but eliminates the

need to power the CarDAQ-Plus before booting your computer.

Procedure for Fixed IP addressing:

1. On your computer, find your network card configuration. Turn off "Obtain an IP address

automatically" and enter the IP address 192.168.43.102 and the netmask 255.255.255.0. For step-

by-step instructions on setting up your computer for Fixed IP addressing, see Appendix B:

Instructions for configuring your network card.

2. Connect power and Ethernet cables to the CarDAQ-Plus. Use the direct-connect cable (blue with

red ends) when connecting directly to the PC (without an Ethernet hub).

3. Wait for the Orange 'Busy' light on the front to stop blinking.

4. Verify that the Ethernet Link light (on the upper right of the Ethernet port) is on.

5. Verify that the green Heartbeat LED is blinking in a regular pattern, two beats per second. This

means that the CarDAQ-Plus is in DHCP server mode.

6. On your PC or laptop, start a web browser and enter http://192.168.43.101/

in the location bar.

If the CarDAQ-Plus 'About' page is not displayed, see the Troubleshooting Guide.

Connecting to an existing network with automatic addressing

Most corporate networks or home networks have a DHCP server for automatic network configuration. The

CarDAQ-Plus can use this server, as long as the network is connected before power is applied. It is

recommended that the CarDAQ-Plus boot mode be changed to Client only see

CarDAQ-Plus has been carefully designed and tested to comply with OBDII protocols, which are used on most

1996 and newer cars and light trucks sold in the USA. However, some vehicle models are not in full

compliance with these protocols for various reasons. In addition, the computer control systems or sensors on

any given vehicle may be malfunctioning or out of specification.

Vehicles manufactured for use outside of the USA may not comply with OBDII protocols, even though an SAE

J1962 connector is located in the vehicle. Connection to vehicles manufactured for use outside of the USA is

AT YOUR OWN RISK. Drew Technologies will not be held responsible for ANY direct, indirect or consequential

damage that arises as a result of connecting to such a vehicle.

Before installing CarDAQ-Plus, be sure to review the list of known vehicle exclusions and anomalies. For more

information on OBDII issues and anomalies in general, we recommend The Equipment and Tool Institute's
