1. Note that the transmitter should be disabled prior to changing the Logging Rate of a sensor in the Sensor Log Table then re enable the transmitter once the changes have been made If this is not done the Logging Rate that appears in the header at the beginning of any given line may not correspond to all the entries in that line This is because the header displays information that was current when the Most Recent Entry took place For instance in the example above the Logging Rate was set to 15 minutes If this had been changed to 10 minutes when eight readings had already been loaded into the corresponding GOES buffer the header would display 10 not 15 minutes as such HG 2 10 0 6280 0 7293 0 7800 0 7800 0 7800 0 7800 0 7800 0 7800 0 7800 0 7800 0 7800 0 7800 l y 00 35 GMT The readings on the left occurred at 10 minute intervals but the remaining readings were logged at 15 minute intervals 00 25 GMT 25 GMT To avoid this confusion disable the transmitter when making changes to the Logging Rate then re enable it 4 4 1 GOES Data Interpretation 56 4 4 Direct Communications Commands The PDAS SDI supports a number of Direct Communications Commands By Direct Communications we refer to communications that do not take place within the menu system Simply exit the menu with 7 exit and enter the following commands to determine which are supported Identification Command Command I lt cr gt Response lt id
