Blink mode recovery

This article goes over the process to recover your OxTS system from the Blink recovery mode. The main topics are:

• Overview
• Choosing the right recovery process
• Standard recovery process
• xDEV based unit recovery process
• Note for using FTP clients

Overview

During firmware upgrade process you may have issues connecting to your unit via FTP or even not be able to see it on the network. This can be due to an interruption during the process of transferring the firmware to the unit or if the firmware was transferred with the wrong protocol (e.g. FTP ASCII format not binary).

When in this state the unit will cycle on and off every 2 minutes. The recovery process that is relevant is dependent upon the type of firmware the unit is running. If the lights are blinking in the following fashion then 

• rtbns The SDNAV and Position LED's will be flashing alternately
• xbns The GNSS light is flashing alternately red/green 

Choosing the right recovery process

There are two categories of units and recover process in slightly different depending on which category the unit is in. Please choose the right method from this table:

Standard models recovery process

1. You will need to be ready with the relevant firmware file for the unit you have which if you do not have it is obtainable from your local agent or via OxTS Support. The firmware files required are:
   
   

   rtbns	RT2000	RT3000	RT4000	Inertial+	Survey+
   xbns	xNAV	xOEM	ABD	inMOTIONx
   rtrange	RT-Range

2. Once you have the relevant file, connect your PC to the unit via ethernet
3. You have 2 minutes during the unit's automatic power cycle to do this small process.
4. Once your PC is connected to the OxTS unit open an explorer window
5. Choose the relevant IP address from this table:
   
   

   195.0.0.180	rtbns based units
   195.0.0.132	xbns based units
   195.0.0.181	RT-Range units

6. The explorer window should now show a folder location on the unit where you can copy the firmware file into. Alternatively you can use FTP client software to perform this section but take note of this before doing so.
7. Close the window once completed and the file is fully copied
8. Toggle the unit off / on or wait the 2 minutes for it to cycle itself
9. It should now have corrected the IP address
10. Run NAVConfig as per setup or use default settings
11. Open NAVdisplay - and check the IP address comes up and connect to it
12. Check the connect tab to confirm the firmware version

xDEV based models recovery process

xDEV based units have two remotely upgradeable firmware types:

xbns recovery process

In the case that xbns has crashed, you need to: 

1. Try resetting the device as the xbns may have failed but not be corrupt
2. If the LED demonstrate the same pattern then continue
3. You will need to be ready with the xbns firmware (contact support@oxts.com for more info)
4. Once you have the relevant file, connect your PC to the unit via ethernet
5. Once your PC is connected to the OxTS unit open an explorer window
6. Navigate to the standard IP address
7. The explorer window should now show a folder location on the unit where you can copy the firmware file into. Alternatively you can use FTP client software to perform this section but take note of this before doing so.
8. Close the window once completed and the file is fully copied
9. Toggle the unit off then on
10. It should now have correct/original IP address
11. Run NAVConfig as per setup or use default settings
12. Open NAVdisplay - and check the IP address comes up and connect to it
13. Check the connect tab to confirm the firmware version 

xDEV recovery process

In the case that xDEV has crashed, you need to: 

1. You will need to be ready with the xDEV firmware (contact support@oxts.com for more info)
2. Once you have the relevant file, connect your PC to the unit via ethernet
3. Once your PC is connected to the OxTS unit open an explorer window
4. Navigate to the 195.0.0.133 IP address
5. The explorer window should now show a folder location on the unit where you can copy the firmware file into. Alternatively you can use FTP client software to perform this section but take note of this before doing so.
6. Close the window once completed and the file is fully copied
7. Toggle the unit off / on or wait the 2 minutes for it to cycle itself
8. It should now have correct/original IP address
9. Run NAVConfig as per setup or use default settings
10. Open NAVdisplay - and check the IP address comes up and connect to it
11. Check the connect tab to confirm the firmware version 

Note for using FTP clients

Unfortunately, some FTP transfer programmes such as Filezilla default to transmitting any file that does not have an extension (like rtbns/xbns) as an ASCII text file. The setting “Treat files without extension as ASCII file” circled in red below is the one that you need to change. It should not be checked.

Note: It is essential that the file transfer mode is set to Binary and not ASCII.
