The firmware in the Inertial+, Survey+, RT2000, RT3000 and RT4000 can only be updated using Ethernet.
2. Check Files
The software is a file called rtbns. The name has no extension and must be in lower case. If the file is zipped, the extension might have been changed (e.g. to .piz) so that it is not rejected by email security systems. If so, change it to .zip, then unzip the file.
3. Connect Ethernet
The RJ45 Ethernet connector on the RT can be plugged in to a network hub. To connect it directly
to a laptop a crossover must be used. The RT is supplied with a suitable cable for connection to a
laptop computer. The IP address of the laptop must be in the same subnet as the RT, in other words the IP address should begin 195.0.0. (by default) and end with a number lower than 255 that is different from the RT.
4. Viewing Raw Data on RT
Explorer can be used to connect to the RT.
Open Explorer. In the address box type: ftp://195.0.0.m where m is the address of the RT, as shown in the screenshot below.
On older systems it is necessary to supply a user name and password. Type: ftp://user:firstname.lastname@example.org
Explorer will list all the raw data files that are stored in the RT.
If Internet Explorer automatically opens when you try to connect over FTP, open the Internet Options, Advanced tab and tick the setting to enable FTP folder view outside of Internet Explorer (see below).
5. Back up old files
Before updating the firmware, back-up any RD files you may need.
Do not delete the files that start with mobile. These are your configuration files and should only be changed using the RT-Config. (The file mobile.rd can be deleted, but the system will put it back).
6. Applying the firmware
The firmware will have been sent to you in a file called rtbns. It must be called this before it can be copied to the RT. All letters must be lower case and there must be no extension. If it is zipped it must be unzipped before it is copied to the RT.
To copy the firmware drag-and-drop it in the Explorer window.
Wait 10 seconds, turn off the RT and turn it back on again
7. Check firmware version
Run NAVdisplay and connect to the RT as normal. In NAVconnect the firmware id is displayed, as shown below.
This should be the same as the new software that you installed. The name of the zipped file containing the firmware will tell you the version (or Development ID) of the rtbns software.
