Prerequisites
This procedure assumes that:
|
• |
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. |
Neither tools nor instruments are required.
Context
The motion reference unit (MRU) measures the roll and pitch movements of the vessel. Some sensor models also measure heave. The information provided by the motion sensor is used by the SU90 system to stabilize the beams.
NoteThis task is only applicable is you are using an external motion reference unit on your SU90 system.
Procedure
|
1 |
Connect the motion sensor system to an available communication port on your computer.
This is described in the Installation Manual.
|
|
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.
|
|
|
NoteIf 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.
|
a |
On the left side of the Installation dialog box, select I/O Setup. |
|
b |
Observe that the available serial interface ports on the Processor Unit are listed. |
|
c |
If you have a vacant COM port, select it, then select Remove to delete it from the list. |
|
d |
At the bottom of the page, select Apply to save your settings. |
|
e |
Close the Installation dialog box. |
|
f |
Restart the SU90 system.
Restarting allows the Processor Unit to "free" the port.
|
|
g |
When the SU90 system has started, proceed to the Motion Reference Unit page to put the communication port to use. |
|
|
5 |
On the left side of the Installation dialog box, select Motion Reference Unit. |
|
6 |
Set up the interface.
|
a |
Select the Ethernet port or serial port you want to use. |
|
b |
Select which protocol (datagram sentence) you want to use. |
|
c |
If you are using a serial line, define the baud rate. |
|
|
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. |
Further requirements
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.
