For experienced users only. Please follow the instructions carefully since changing the configuration of the GNSS receiver can affect the INS performance if done incorrectly.

To request the additional logs (in this example it is GSV), please do the following:

1. Connect to the COM2 of the INS (XS4 upper DB9 connector)  on your computer using any serial port terminal (for example RealTerm). Check at the Device Manager window (Control Panel/System and Security/System/Device Manager) which СOM port number was assigned by the Windows system.
   
   
   
   At RealTerm set the appropriate COM port number and baud rate and click Open:
   
   
   
2. Power on the INS and wait until the LED color changes to red or green (in the case of the Autostart mode).
3. When the connection is established, please go to Send tab and enter the following command to the GNSS receiver:
   FRESET
   Enable +CR and +LF and click Send ASCII
   
   
   
   
4. Wait approx. 10 seconds. If there was any data flow on the COM2, it should stop after the command from step 3 is received. If your goal is only to factory reset the receiver, proceed to step 7.
5. After the FRESET command is received by the GNSS receiver its baud rate is set to default - 9600 bps. Please change the baud rate in the serial port terminal to 9600 to allow a receiver to get the commands.
   
   
   
   
   
6. To make the receiver output GPGSV messages, send the following commands to the receiver:
   LOG COM2 GPGSV ONTIME X - if you want to receive GSV message on COM2, X - is the period
   or
   LOG COM3 GPGSV ONTIME X - if you want to receive GSV message on COM3, X - is the period.
   
   
   
7. Send the following command to the receiver to save the changes:
   SAVECONFIG
   
8. Wait 10 seconds and power-cycle the INS unit. Please run the INS again and you will get GSV message on COM2 or COM3.
