• | You have a vacant interface port on your Processor Unit. |
• | A suitable receiver system must be available. |
• | 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. |
1 | Connect the receiver to an available communication port on the Processor Unit. 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.
|
4 | On the left side of the Installation dialog box, select Sensor Installation. |
5 | For Type, select External Objects to import information from relevant devices. |
6 | Select which port you want to import the sensor information on. |
7 | If you want to check the communication parameters, select Inspect Port. Note
You cannot make any changes here. To change the communication parameters, use the I/O Setup page.
|
8 | If you want to check that the peripheral system is transmitting data to the SU90 system, select Monitor. The Port Monitor dialog box provides one text box for incoming messages (Rx Data), and one for outgoing messages (Tx Data). Use these boxes and your knowledge of the data communication to investigate the datagrams. The Port Monitor dialog box is a tool for debugging purposes. It is neither required nor intended for normal operation of the SU90 system.
|
9 | Type a custom name to identify the interface in other dialog boxes. |
10 | Select which datagram(s) you want to import from the sensor. |
11 | If relevant, specify a dedicated talker ID. |
12 | Select Add to save the new sensor interface you have defined. The sensor interface is added to the Installed Sensors list on the Sensor Installation page.
|
13 | At the bottom of the dialog box, select Apply to save your settings. |
14 | Continue your work in the Installation dialog box, or select OK to close it. |
