• | You have a vacant interface port on your Processor Unit. |
• | You are familiar with NMEA and other relevant datagram formats. |
• | You know how to set up the parameters for serial and local area network (LAN) communication. |
• | The interface port is set up with the correct communication parameters. |
• | The SU90 system is turned on and operates normally. |
• | The new sensor is physically connected to the SU90 system using a serial or network cable. The sensor is turned on and in normal operation. |
1 | Connect the motion sensor system to an available communication port on your computer. This is described in the Cable layout and interconnections chapter. Observe the applicable requirements related to cabling. Make sure that the total length of the serial line cable does not exceed approximately 50 meters. If a longer cable is required, you may need to use buffer amplifiers.
If the computer is not fitted with a suitable serial line connector, use a USB-to-serial converter. Several types are commercially available. Note that most USB-to-serial converters will introduce some latency. They may also introduce jitter in the communication. The amount of jitter depends on the quality of the converter.

2 | Open the Setup menu. |
3 | On the Setup menu, select Installation.![]() Observe that the Installation dialog box opens. This dialog box contains a number of pages selected from the menu on the left side.
|
Note
If you want to use a serial line to interface the motion sensor, and no COM ports are available, you must first release a
port on the I/O Setup page. If you choose a serial COM port to interface the motion sensor, make sure that you do not put the same COM port to other use
on the I/O Setup page.
|
4 | Release an unused serial port (COM) port.
|
5 | On the left side of the Installation dialog box, select Motion Reference Unit. |
6 | Set up the interface. If you select to use the LAN port, the SU90 system will automatically use the built-in motion sensor. Select COMx to connect to the external motion sensor. "COMx" is the serial port to which the motion sensor is connected. Select None to disconnect the SU90 system from both external and internal motion sensors.
|
7 | At the bottom of the dialog box, select Apply to save your settings. |
8 | Continue your work in the Installation dialog box, or select OK to close it. |
