### Step 2: Connect the Leica Tracker

Communication with the Leica Tracker is accomplished using the TCP/IP protocol via a cross-over cable that is connected directly to the Leica Tracker Controller (LTC plus/base). This is the preferred method for connection, but you may also connect over your local area network (LAN). For detailed information about setting up your Leica Tracker hardware, see the Laser Tracker Hardware Guide that came with your tracker.

To connect to your Leica Tracker:

1. Secure your tracker in the position from which you will first take measurements.

2. Connect your tracker to the LT controller's "Sensors" and "Motors" ports.

3. Mount the T-Cam (if you are using one) to the top of the tracker and connect T-Cam cable from the tracker to the LT controller.

4. Attach the Meteo station to the serial port on the LT controller if you have one. The Meteo station is used to report environmental data to the LT controller.

5. Directly connect your LT Controller to the computer where PC-DMIS is installed via a cross-over cable with RJ45 connecters. You may also connect the LT controller to the network (LAN) via a twisted-pair ethernet cable.

6. Turn on the power to the LT controller which provides power to the Leica Tracker as well.

7. Check the status display on the back of the LT controller. This provides information about the IP address (typically 192.168.0.1/255.255.255.0), name, emScon firmware version, and current operation. If your LT controller has a different IP address than the standard 192.168.0.1, do one of the following:

- Change the IP Address from the "Options tab" of the Machine Options dialog box to the new IP Address of the controller.

- Use the PC-DMIS Settings Editor and change the TrackerIPAddress entry to the new IP Address of the controller. See the "Editing PC-DMIS Registry Entries" section of the PC-DMIS Settings Editor help file for information on editing registry settings.

8. Make sure that the IP address for the PC-DMIS computer is in the same subnet as the controller (e.g. if the LT controller has an address of 192.168.0.1, then you would need to assign an address between 192.168.0.2 and 192.168.0.254). You must avoid IP Address conflicts with other devices on the same network.

9. Type PING 192.168.0.1 (or a different address of your controller) from the command prompt on the PC-DMIS computer to verify communication to the LT controller.

Important: The Leica Tracker should be powered on for at least 4 hours to ensure the most accurate measuring result. If you are not going to be using the laser for a while you should turn it off to conserve the laser's life-span. However, each time you turn it on, it takes 20 minutes to warm-up.
