Figure 9.1.6-2: Performing a ColdStart 6) Reload the setup file. Refer to Initial VBOX Setup, step 5. NOTE: VBOX setup must be repeated; if the VBOX is not configured properly, it will be unable to communicate with the eDAQ. D-76
9.2. Appendix B: Additional Information Regarding Data Collected 9.2.1. Data Comments Prematurely ending a run - If a vehicle bus module loses its connection with the eDAQ, the run will be ended. - If the connections between the vehicle bus module(s) and the eDAQ are remade, the eDAQ will record data as usual beginning with the next run. Invalid data - The invalid data value (generally the highest possible value for a channel) indicates that the eDAQ is unable to receive information from the sensor. The connection between the sensor and its associated vehicle bus module (or COMM port, depending on the sensor) is at fault. - The invalid data value for computed channels is derived from the associated transducer channels rather than the “maximum” specified in the channel setup. VBOX - In case of a loss of satellite lock, the VBOX will transmit zeros for all channels except its Time channel; the Time channel will transmit an incrementing value (like a counter). - When satellite lock is obtained, all VBOX values will be corrected. AirWeigh - When AirWeigh_Append is used, it will take up to 2 seconds from the beginning of a run to identify which trailer unit is connected - A change in trailer status will take up to 45 seconds to be properly reflected in all channels (weight, ID, tire flag, marriage indicator). - When the Air-Weigh display is unplugged, values recorded are invalid data values. - When the tractor unit is disconnected, values recorded are invalid data values. 9.2.2. ID Explanations The following Tables contain information regarding each channel of data collected. D-77
