  • Page 13: Connecting To The Thinkrf R5700

    R5700 using SCPI commands, and transmission of data using the VRT protocol. Determining Your Network Topology and IP Address Allocation To connect with the R5700 analyzer, you must decide the topology of your network connection and how your R5700 obtains its IP address.

  • Page 14: Connecting Directly To The R5700

    Ethernet card or USB adapter to connect to the R5700. Note: The Ethernet interfaces on both the PC and the R5700 must be configured for the same IP address allocation method before you can make a direct connection.
  • Page 15 Note: While the R5700 is searching for a DHCP server, the STS LED blinks yellow slowly until it obtains an IP address either via DHCP or Auto-IP. The STS LED blinks in a green heartbeat pattern if it has set up successfully to using an Auto-IP address.

  • Page 16: Connecting To The R5700 Across A Network

    Before you connect to the R5700, you must decide on your IP address allocation method. The PC and R5700 do not need to use the same IP address allocation method, but if you are using the ThinkRF Discovery tool to locate the R5700 analyzer, they must be on the same subnet.

  • Page 18: Using The Thinkrf R5700 Administration Console

    All of these functions may be performed over the network either locally or remotely. You can connect to the R5700 Administration Console by entering the IP address of your R5700 into a web browser. The IP address is shown in the S240 software as the connected device.

  • Page 19: Configuring R5700 Time Synchronization

    Note: The R5700 analyzer stores its time based on the Coordinated Universal Time (UTC) and otherwise has no notion of local time-zones. Conversely, the web dialog translates and displays the R5700 time based on the local time-zone setting of the PC. To configure the R5700 time synchronization method: 1.

  • Page 20: Configuring The R5700 Ip Address

    IP address manually (using a static address). Caution: If the R5700 IP address is set to a static IP, the only way to communicate with the R5700 is via that IP address. If you mistakenly enter the wrong IP address and/or subnet mask, or forget the IP address, you can change the IP configuration using the USB console or by resetting the R5700.

  • Page 21: Updating The R5700 Firmware

    The firmware installation file contains firmware images associated with the R5700 FPGA, Linux operating system and the embedded application. The update process copies the new images to the R5700, but does not remove the currently installed images. The new firmware installation will only take effect after the R5700 is restarted.

  • Page 22: Customizing R5700 Calibration Settings

    You can click OK to proceed, or Cancel to defer the device restart. Note: If the R5700 is not restarted immediately after a firmware install process, then the newly installed firmware will take effect upon the next restart of the R5700 regardless of whether it is a software restart or a power-on reset.
  • Page 23 When the upload is complete, the custom calibration file appears on the list of calibration files. The most recently uploaded file is listed at the top of the table. 4. Restart the R5700 (you can click Restart in the left pane, or toggle the power switch).

  • Page 25: Restarting The R5700

    Using the ThinkRF R5700 Administration Console Restarting the R5700 You can restart the R5700 via the Administration Console. Performing a device reset from the Administration Console is equivalent to a power-on reset. To restart the R5700: 1. Click on the Restart link in the left pane of the Administration Console.

  • Page 26: Using The Thinkrf R5700 Usb Console

    1. Power on the R5700 and wait approximately 30 seconds for boot-up. 2. Connect The USB cable to the R5700 USB console port and your PC’s USB port. Your PC should automatically detect the R5700 as a new USB device and install the appropriate driver.
  • Page 27 7. Refer to the R5700 Programmer's Guide associated with the firmware release of your R5700 for the SCPI commands to use with your R5700 via the USB console terminal window. The firmware release version of the R5700 is returned with the *IDN? SCPI command.

  • Page 28: Configuring The R5700 Ip Address

    The R5700 supports dynamic IP address allocation using DHCP, or manual IP address configuration (via static IP address). Caution: If the R5700 IP address is set to a static IP, the only way to communicate with the R5700 is via that IP address. If you mistakenly enter the wrong IP address and/or subnet mask, or forget the IP address, you can change the IP configuration using the USB console or by restarting the R5700.

  • Page 29: Using The Gnss Module

    R5700 analyzer, the GNSS module also provides a third 10MHz reference clock source option for synchronized time-stamps on VRT packets. You can configure the R5700 to use the GNSS reference clock, via the USB console, or via Telnet or HiSLIP connections. The USB console is used in the following examples.

  • Page 30: Getting Real-Time Geolocation Data

    If no GNSS fix is available, the system response is “INT”. Getting Real-Time Geolocation Data You can obtain real-time GNSS position data from the R5700 GNSS module. During data capture, the real time GNSS location context packets are sent periodically in the VRT data stream.
  • Page 31 When 0 is returned, the GNSS data is current. When 512 (or bit 9) is returned, the GNSS is out of lock. See “Appendix D: Questionable Status Register (QSR) in the ThinkRF R5700 Programmer’s Guide for more information.

  • Page 32: Resetting The Thinkrf R5700 To Factory Settings

    Resetting the ThinkRF R5700 to Factory Settings If for any reason you cannot connect to the R5700 via the Ethernet port, you can restore device factory settings to reset IP configuration, and obtain an IP address dynamically using DHCP. Performing a factory resent also sets the reference level calibration back to factory default values.
