The X-HUB adds two extra USB ports and an Ethernet port to myRIO
With the X-Hub attached the myRIO is accessed through a network interface either over Ethernet or USB. In either case, the myRIO is considered a networked device and is accessed by its IP address or DNS name. The IP address for the myRIO when connected using a USB cable is always 172.22.11.2. The IP address for the myRIO when connected using the Ethernet cable is obtained automatically using DHCP. For a World Skills Robot, the IP address is assigned by the suppled OM5P-AC (white access point), and will reflect the subnet of that device.
If at any point, you would like to check the Ethernet IP address of your myRIO, connect the myRIO using both Ethernet and USB and then open the web interface by typing 172.22.11.2 into the address bar of any internet browser (IE recommended). This web interface shows the Ethernet IP address of the myRIO amongst other information.
User can also check using NI Measurement & Automation Explorer (MAX).
You will need to Install the supplied Configuration Utility software to configure the OM5P-AC for use, this is a custom version supplied to Studica, by First Canada. The OMP5-AC needs 12V 2A power supplied via voltage regulator using the supplied barrel connector and wire.
Power to the OM5P-AC is 12V 2A (center-pin positive).
Install the Supplied Configuration Utility.
Before you begin using the software it is important that you do the following:
1. Disable all WiFi connections on your computer, as it may prevent the configuration utility from properly communicating with the OM5P-AC. (You may need to rebot the local computer)
2. Connect your computer to the OM5P-AC using the supplied Ethernet cable. Make sure no other devices are connected to your computer via Ethernet posts, other than the OM5P-AC.
Note: Teams will need to update firmware on the OM5P-AC in order for the programming utility to work, this must be done before you attempt to program the unit.
The Configuration Utility requires the Java Runtime Engine (JRE). If you do not have Java installed, you can download the JRE from here: https://www.java.com/en/download/
The Configuration Utility requires Administrator privileges to configure the network settings on your machine. The program should request the necessary privileges automatically (may require a password if run from a non-Administrator account), but if you are having trouble, try running it from an local Administrator account.
By default, the utility will program the radio to enforce the 7Mbps bandwidth limit on traffic exiting the radio over the wireless interface.
The utility has been tested on Windows 7, 8 and 10. It may work on other windows operating systems, but has not been tested.
Use the Start menu or desktop shortcut to launch the program.
Use the pop-up window to select the which Ethernet interface the configuration utility will use to communicate with the wireless bridge. On Windows machines, Ethernet interfaces are typically named “Local Area Connection”. The configuration utility can not program a bridge over a wireless connection.
To load the firmware (or reset the radio), you do so using the Radio Configuration Utility.
If you see an error about NPF name, try disabling all adapters other than the one being used to program the radio. If only one adapter is found, the tool should attempt to use that one.
In order to configure IP address for your robot each team will be assigned a TEAM number based upon their countries international country code. Please use the following team numbers:
The following example will use 1111 as the TEAM number.
The default values of the options have been selected to match the use case of most teams, however, you may wish to customize these options to your specific scenario:
Throughout the configuration process, the window will indicate:
The Configuration Utility programs a number of configuration settings into the OM5P-AC when run. These settings apply to the OM5P-AC in all modes.
In AP mode only:
If using the USB interface, no setup is required. The myRIO driver will automatically configure the IP address of the host (your computer) and myRIO and the software listed above should be able to locate and utilize your myRIO
The Configuration Utility will enable the DHCP server on the OM5P. The OM5P will hand out IP addresses as specified above.
myRIO Ethernet Configuration: The myRIO Ethernet interface should be set to DHCP. When connected to the OM5P wired via the X Hub, the myRIO will receive an IP from the bridge. When tethered directly to a PC, both devices will self-assign IPs.
The myRIO will show as a wireless network with the TEAM name and the Robot name as set in the configuration.
On this case, no WPA Key passphrase has been set the connection is Open.
When configuring a myRIO project you can connect over WiFi using the NI-myRIO name or the IP address.
