# BBOB setup ## Equipment needed To install BBOB the following elements are needed: * BBOB unit with its power supply. BBOB requires one mains socket. It can also be supplied from PoE. * One Ethernet cable to connect BBOB to a network and one Ethernet cable for every BBO that will be handled by BBOB (max. 4) There are also additional items that may be needed for the installation itself: * PC * SD card reader to modify config.txt file. It can be also done using terminal connection and then the reader is not necessary. * IP scanner like e.g., to find the BBOB IP address. ## Hardware The BBO Buffer (P/N BBOB) with its power supply is shown below. A power supply delivers 24VDC 0,38A. ![](https://1482390586-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FegpnAPlZcRY7vPT5SNXz%2Fuploads%2Fgit-blob-3e94d508e6dc3f7b9ffabb8638d983ba1858c8c3%2Fimage2.png?alt=media) ![](https://1482390586-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FegpnAPlZcRY7vPT5SNXz%2Fuploads%2Fgit-blob-39544fd20e3e95c5d041298c9912b2b5444c170d%2Fimage3.png?alt=media) The BBOB is delivered with an SD Card (not shown on the picture above), that must be installed in the microSD socket. Please note that the card is installed with its gold pins pointing up. Its end shall be parallel to the back side, protruding about 3 mm. This card contains configuration data and is used as a storage space for BBO measurements. The detailed information can be found in [sd-card-contents-after-installation](https://help.boomerang3.com/bbo-buffer-installation-manual/bbob_production/running_installation_script/sd-card-contents-after-installation "mention"). There are 5 Ethernet sockets. The one marked “Internet” is called WAN in this manual and shall be connected to the network with access to B3 server. The BBO units shall be connected to four LAN sockets marked 2, 3, 4 and 5. All the LAN sockets work exactly the same. The power supply shall be connected to the power socket on the left side. ## Software settings The only setting that must be defined in the BBO Buffer is the B3 server URL in config.txt file on BBO Buffer SD card. To set the B3 URL remove the SD card from the BBO Buffer socket at the back, put it into a card reader and edit the config.txt file with any text editor like Notepad. The config.txt file contains two rows:\ IP address or URL name of B3 server\ port (default 54000) Example contents of config.txt:\ \boomerang3demo.com\\ \54000\ **Do not enter any unnecessary characters in the config.txt file!**\ **There shall not be http or https in front of the B3 URL.** Please note that if an URL name is used then the BBOB must know the DNS server to resolve the address. You may access the BBOB to change its configuration or check its status using its web interface or terminal SSH connection as described in [access\_bbob](https://help.boomerang3.com/bbo-buffer-installation-manual/advanced_use/access_bbob "mention"). --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
