Step 1 – Introduction
The firmware in the RT-Range can only be updated using Ethernet. The first sections in this guide give instructions on how to configure the Ethernet on a PC running Windows. If your PC is already configured to communicate with the RT-Range over Ethernet, please jump straight to step 6.
Step 2 – Check Files
The software is a file called rtrange. It has no extension and must be in lower case. Unzip it if it is zipped.
Step 3 – Connect Ethernet
Use a standard Ethernet Cable (not a cross-over) to connect the RT-Range Hunter to the computer. The RT-Range is supplied with a suitable cable for connection to a computer.
CHECK: If the cable is working correctly then the light on the hub or PC will light up when
connected to the RT-Range, as shown below.
Step 4 – Configure Windows
Your PC may already have a TCP/IP network configuration. This may need to be changed before you can connect to the RT-Range; changing your network configuration may prevent
your computer from working on your current network.
From Windows menu select the Control Panel. Next, select Network and Internet and then Network and Sharing Center.
Select the Local Area Connection from the network information window.
The Local Area Connection Status dialog box will be shown. Click on the Properties
button to change the properties of your network.
Click on Internet Protocol Version 4 and then click on Properties.
Now the settings can be configured.
The IP address used should be 195.0.0.n where n is not the same as the RTRange.
The settings shown below should work correctly.
Once set, press OK. Press OK again in the Local Area Connection Status window.
Step 5 – Check Network Settings
From Windows menu choose Run... Then in the box that appears type “cmd”.
In the Command Window type ipconfig. This program displays the Internet Protocol Settings. The IP Address and the Subnet Mask should be as shown below. The Default Gateway can be blank.
Step 6 – Viewing Files on RT-Range
After the network is configured correctly, Windows Explorer can be used to connect to the RT-Range.
Open Windows Explorer. In the address box type:
where m is the address of the RT-Range.
Windows Explorer will list all the configuration files that are stored in the RT-Range.
Step 7 – Copying the Firmware
The firmware will have been sent to you in a file called rtrange. It must be called this before it can be copied to the RT-Range. 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-Range.
To copy the firmware drag-and-drop it in the Windows Explorer window.
Close Windows Explorer. Wait 10 seconds, turn off the RT-Range and turn it back on again.
Step 8 – Checking Firmware Version
To check the firmware version it is necessary to set up the RT-Range in a vehicle and have it connected to an RT3000. The RT-Range will only transmit data once it is receiving data from an initialised RT3000.
Once the RT-Range is transmitting data insert a test item in to the list Real-Time display items. Choose the Data Type “RT-Range Firmware Dev ID” from this list.
(See RT-Range Measurements, Range measurements from Hunter to Target, Range Status Information in the tree list).
If the update fails for any reason then the Range fall fall back onto IP 220.127.116.11 and communication on the usual IP address will not be possible. If this occurs then please repeat steps 6, 7 & 8 using the 18.104.22.168 for communication.
Please note that failures usually occur due to interruptions in communication, power interruptions or the firmware being transferred as an ASCII file rather than a binary file due to the way that some versions of Windows handle file transfers when files do not have extensions.
