+------------------------------------------------------------------------ +Daughterboard Modifications +------------------------------------------------------------------------ + +Sometimes, daughterboards will require modification +to work on certain frequencies or to work with certain hardware. +Modification usually involves moving/removing a SMT component +and burning a new daughterboard id into the eeprom. + +^^^^^^^^^^^^^^^^^^^^^^^^^^^ +DBSRX - Mod +^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +Due to different clocking capabilities, +the DBSRX will require modifications to operate on a non-USRP1 motherboard. +On a USRP1 motherboard, a divided clock is provided from an FPGA pin +because the standard daughterboard clock lines cannot provided a divided clock. +However, on other USRP motherboards, the divided clock is provided +over the standard daughterboard clock lines. + +**Step 1: Move the clock configuration resistor** + +Remove R193 (which is 10 ohms, 0603 size) and put it on R194, which is empty. +This is made somewhat more complicated by the fact that the silkscreen is not clear in that area. +R193 is on the back, immediately below the large beige connector, J2. +R194 is just below, and to the left of R193. +The silkscreen for R193 is ok, but for R194, +it is upside down, and partially cut off. +If you lose R193, you can use anything from 0 to 10 ohms there. + +**Step 2: Burn a new daughterboard id into the EEPROM** + +With the daughterboard plugged-in, run the following commands: +:: + + cd <install-path>/share/uhd/utils + ./usrp_burn_db_eeprom

thread requirements:** +It is safe to call send() and recv() simultaneously.

remain solid. + +When in safe-mode, the USRP-N device will always have the IP address 192.168.10.2 + +------------------------------------------------------------------------ +Setup networking +------------------------------------------------------------------------ +The USRP2 only supports gigabit ethernet, +and will not work with a 10/100 Mbps interface. +However, a 10/100 Mbps interface can be connected indirectly +to a USRP2 through a gigabit ethernet switch. + +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ +Setup the host interface +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ +The USRP2 communicates at the IP/UDP layer over the gigabit ethernet. +The default IP address of the USRP2 is **192.168.10.2** +You will need to configure the host's ethernet interface with a static IP address to enable communication. +An address of **192.168.10.1** and a subnet mask of **255.255.255.0** is recommended. + +**Note:** +When using the UHD, if an IP address for the USRP2 is not specified, +the software will use UDP broadcast packets to locate the USRP2. +On some systems, the firewall will block UDP broadcast packets. +It is recommended that you change or disable your firewall settings. + +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ +Multiple devices per host +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ +For maximum throughput, one ethernet interface per USRP2 is recommended, +although multiple devices may be connected via a gigabit ethernet switch. +In any case, each ethernet interface should have its own subnet, +and the corresponding USRP2 device should be assigned an address in that subnet. +Example: + +**Configuration for USRP2 device 0:** + +* Ethernet interface IPv4 address: 192.168.10.1 +* Ethernet interface subnet mask: 255.255.255.0 +* USRP2 device IPv4 address: 192.168.10.2 + +**Configuration for USRP2 device 1:** + +* Ethernet interface IPv4 address: 192.168.20.1 +* Ethernet interface subnet mask: 255.255.255.0 +* USRP2 device IPv4 address: 192.168.20.2 + +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ +Change the USRP2's IP address +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ +You may need to change the USRP2's IP address for several reasons: + +* to satisfy your particular network configuration +* to use multiple USRP2s on the same host computer +* to set a known IP address into USRP2 (in case you forgot) + +**Method 1:** +To change the USRP2's IP address +you must know the current address of the USRP2, +and the network must be setup properly as described above. +Run the following commands: +:: + + cd <install-path>/share/uhd/utils + ./usrp_burn_mb_eeprom --args=<optional device args> --key=ip-addr --val=192.168.10.3 + +**Method 2 (Linux Only):** +This method assumes that you do not know the IP address of your USRP2. +It uses raw ethernet packets to bypass the IP/UDP layer to communicate with the USRP2. +Run the following commands: +:: + + cd <install-path>/share/uhd/utils + sudo ./usrp2_recovery.py --ifc=eth0 --new-ip=192.168.10.3 + +------------------------------------------------------------------------ +Communication problems +------------------------------------------------------------------------ +When setting up a development machine for the first time, +you may have various difficulties communicating with the USRP device. +The following tips are designed to help narrow-down and diagnose the problem. + +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ +Firewall issues +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ +When the IP address is not specified, +the device discovery sends broadcast UDP packets from each ethernet interface. +Many firewalls will block the replies to these broadcast packets. +If disabling your system's firewall, +or specifying the IP address yeilds a discovered device, +then your firewall may be blocking replies to UDP broadcast packets. +If this is the case, we recommend that you disable the firewall, +or create a rule to allow all incoming packets with UDP source port 49152. + +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ +Ping the device +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ +The USRP will reply to icmp echo requests. +A successful ping response means that the device has booted properly, +and that it is using the expected IP address. + +:: + + ping 192.168.10.2 + +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ +Monitor the serial output +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ +Read the serial port to get debug verbose from the embedded microcontroller. +The microcontroller prints useful information about IP addresses, +MAC addresses, control packets, fast-path settings, and bootloading. +Use a standard USB to 3.3v-level serial converter at 230400 baud. +Connect GND to the converter ground, and connect TXD to the converter receive. +The RXD pin can be left unconnected as this is only a one-way communication. + +* **USRP2:** Serial port located on the rear edge +* **N210:** Serial port located on the left side + +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ +Monitor the host

+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ +Single device configuration +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ +In a single-device configuration, +the USRP device must have a unique IPv4 address on the host computer. +The USRP can be identified through its IPv4 address, resolvable hostname, or by other means. +See the application notes on `device identification <./identification.html>`_. +Use this addressing scheme with the *single_usrp* interface. + +Example device address string representation for a USRP2 with IPv4 address 192.168.10.2 + +:: + + addr=192.168.10.2 + +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ +Multiple device configuration +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ +In a multi-device configuration, +each USRP device must have a unique IPv4 address on the host computer. +The device address parameter keys must be suffixed with the device index. +Each parameter key should be of the format <key><index>. +Use this addressing scheme with the *multi_usrp* interface. + +* The order in which devices are indexed corresponds to the indexing of the transmit and receive channels. +* The key indexing provides the same granularity of device identification as in the single device case. + +Example device address string representation for 2 USRP2s with IPv4 addresses 192.168.10.2 and 192.168.20.2 +:: + + addr0=192.168.10.2, addr1=192.168.20.2 + +------------------------------------------------------------------------ +Using the MIMO Cable +------------------------------------------------------------------------ +The MIMO cable allows two USRP devices to share reference clocks, +time synchronization, and the ethernet interface. + +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ +Shared ethernet mode +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ +In shared ethernet mode, +only one device in the configuration can be attached to the ethernet. +This device will be referred to as the master, and the other device, the slave. + +* The master provides reference clock and time synchronization to the slave. +* All data passing between the host and the slave is routed over the MIMO cable. +* Both master and slave must have different IPv4 addresses in the same subnet. +* The master and slave may be used individually or in a multi-device configuration. +* External clocking is optional, and should only be supplied to the master device. +* The role of slave and master may be switched with the "mimo_mode" device address (see dual ethernet mode). + +Example device address string representation for 2 USRP2s with IPv4 addresses 192.168.10.2 (master)

+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ +Dual ethernet mode +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ +In dual ethernet mode, +both devices in the configuration must be attached to the ethernet. +One of the devices in the configuration will be configured to provide synchronization. +This device will be referred to as the master, and the other device, the slave. + +* The master provides reference clock and time synchronization to the slave. +* The devices require the special device address argument "mimo_mode" set. +* Both master and slave must have different IPv4 addresses in different subnets. +*
