Communication with this 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 the 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 connectors. 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. For information on editing registry settings, see the "Editing PC-DMIS Registry Entries" chapter of the PC-DMIS Settings Editor documentation.

8. Make sure that the IP address for the PC-DMIS computer is in the same subnet as the controller. For example, 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.

Communication with this Leica Tracker is accomplished using the TCP/IP protocol via a cross-over cable that is connected directly to the Leica AT Controller 400. 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 intend to first take measurements.

2. Install batteries in the tracker and the tracker controller. The tracker must have a battery in the bay in order to measure. However, the battery in the AT Controller 400 is optional.

3. Connect your tracker to the AT controller's "Sensors" port.

4. Optionally connect the power input to the power port on the AT controller. Note, if there is a battery installed in the AT controller and the external power is connected, the battery does NOT charge. This is due to the amount of heat generated by lithium-ion batteries while they charge.

5. Directly connect your AT Controller 400 to the computer where PC-DMIS is installed via a cross-over cable with RJ45 connectors. You may also connect the AT controller to the network (LAN) via a twisted-pair Ethernet cable.

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

7. Check the status display on the face of the AT controller. You are prompted to level the device first since the Nivel is integrated into the AT 400 unlike the add-on with the LT controllers. The display on the top face of the AT controller also provides you with the ATC400 firmware version, system status, graphical connection information, and weather information. To access the different views press the down arrow button.

8. Make sure that the IP address for the PC-DMIS computer is in the same subnet as the controller. For example, if the AT 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.
