CSAT3 Three Dimensional Sonic Anemometer deasserted, e.g. RS-232 communicates have terminated. The baud rate can not be changed if RI=1 (always power the RS-232 drivers). Check the setting of RI in the Long Status Message. "ri n" - Toggle Rts Independent; where n = 0 means power the RS-232 drivers if RTS is asserted and n = 1 means always power the RS-232 drivers. Always powering the RS-232 drivers allows the use of short haul modems between the CSAT3 and PC. "sr2718" - Save RAM contents, with modified calibration parameters, to nonvolatile EEPROM. The command is ignored if the hardware jumper is set in normal operate mode (center and right pins). To change the hardware jumper between normal operate and save to EEPROM mode, follow the steps below. Remove all external connectors from the CSAT3 electronics box. Place the electronics box on a workbench in front of you. Orient the electronics box such that the connectors point towards your body and the silk screening, on the CSAT3 electronics box lid, is pointing towards the ceiling. These instructions reference the location of various components as top, bottom, left, and right. The Campbell Scientific logo is in the top left corner of the electronics box lid. Loosen the four electronics box cover retaining screws with the large Phillips screw driver. Remove the electronics box cover to gain access to the printed circuit board. Locate the CSAT3 processor's surface-mount socket on the CPU Board. The processor is a large chip located near the center of the printed circuit board. The label on the processor will have the Campbell Scientific logo on it as well as the embedded code version number. Locate the row of three pins above and a little to the left of the processor. These pins run from left to right and there is a movable jumper connecting the center pin and the right pin. Note, be sure to return the jumper to the normal operating position, center and right pins. When the jumper is on the center and right pins, the CSAT3 is in the normal operate mode. When the jumper is on the left and center pins, the CSAT3 is in the save to EEPROM mode. 44
