They haven't been tested yet as of 19 Feb. 2014. * The manual states the remote computer should be running Windows 2000 or XP. - Remove the cover plate from the left side of CSI dome. - Connect the monitor crossover cable between the impactor and the remote computer. Power up the remote computer. - Power up the impactor. - On the remote computer, click on **Start**, right click on **My Network Places**, click on **Search for Computers**, enter 10.10.10.10 and hit **Search**. The system should find the impactor directory C. - Double click on C, and the directory listing of the impactor will appear. Go to the data directories and copy over the data as needed. It is recommended that the data be deleted from the impactor computer after it has been archived at another location. ===== Output Data Channels ===== Main Data File ^ Short Name ^ Units ^ Long Name ^ | time | HH:MM:SS | Time | | meas_supp | lpm | Measured Supply | | meas_bypass | lpm | Measured Bypass | |meas_sample | lpm | Measured Sample | | count_flo | lpm | Counter Flow | | tdl_h2o | g/m3 | TDL H2O | | tdl_press | mb | TDL Chamber Pressure| | tdl_temp | C | TDL Cell Temp | | tip_temp | C | Tip Temp | | tube_temp | C | Tube Temp | | amb_temp | C | Ambient Temp | | rtd_resist | Ohms | RTD Resistance | | field_wv | | Field Calibrated Water Vapor| | twc | mg/m3 | Total Water Content| | air_speed | m/s | Air Speed | | temp_5 | | Temp 5 | | temp_6 | | Temp 6 | | temp_7 | | Temp 7 | | volt_6 | | Volt 6 | | volt_7 | | Volt 7 | | numb_conc | #/cm3 | Number Concentration| | vol_conc | um/cm3 | Volume Concentration| | lwc | g/m3 | Liquid Water Concentration| | mvd | um/cm3 | Median Volume Diameter(MVD)| | eff_dia | um | Effective Diameter| TDL Output File ^ Short Name ^ Units ^ Long Name ^ | time | HH:MM:SS | Time | | tdl_1 | g/m3 | TDL 1 | | tdl_2 | mb | TDL 2 | | tdl_3 | C | TDL 3 | | pp2f | | PP2F | | power | | Power | | index | | Index | | zero | | Zero | | t_laser | | T laser | | t_sink | | T sink | ===== Calibration Coefficients ===== Cal.Coeff.
