CSAT3B Three-Dimensional Sonic Anemometer NOTE To collect data through another means (CPI, RS-485, USB), the CSAT3BCBL1 Power/SDM cable may still be used to provide power to the CSAT3B, in which case the SDM wires should be left unwired to any ports on the datalogger. FIGURE 5-3. Options for CSAT3BCBL1 Power/SDM cable Power Cable (CSAT3BCBL2) To use CPI, RS-485, or USB communications to collect data from a CSAT3B, the CSAT3BCBL2-L-PT or CSAT3BCBL2-L-MC should be ordered to provide power to the sensor. A second cable to transmit the communications is also required (for example, CSAT3BCBL3 CPI/RS-485 cable for CPI or RS-485, or the 30179 USB data cable). For installations with long cable lengths, the CSAT3BCBL2 is preferred over the CSAT3BCBL1 for providing power due to the heavier gauge wires that reduce voltage drop over long distances. FIGURE 5-4. Options for CSAT3BCBL2 power cable CPI/RS-485 Cable (CSAT3BCBL3) To use CPI or RS-485 communications to collect data from a CSAT3B, the CSAT3BCBL3-L-PT, CSAT3BCBL3-L-RJ, or CSAT3BCBL3-L-MC, should be ordered in addition to a cable to provide power to the sensor (for example, either the CSAT3BCBL1 or CSAT3CBL2). 12
