No Data This means that data expected from the DDA gauge was not received in the allocated time frame This error is likely to be encountered if the DDA gauge goes to sleep before completion of the data transmission Unexpected activity on the EIA485 bus will cause a DDA gauge to go into sleep mode This error could also be generated if a gauge lost adequate power before completing its data transmission The DDA gauges under certain circumstances may generate error codes i e Exxx See the section on DDA ERROR CODES in the DDA Operation and Instruction Manual P N 550164 if you need more information If the DDA gauge being scanned generates an error you will see the resulting error code beside the parameter to which it relates For example if you request Level 2 data and the gauge is only programmed for one float which would give you only level 1 you will see an E101 DDA error code located beside the Level 2 parameter 6 2 2 Scan O ptions Shown below is a list of all available scan options built into the HT100 and the corresponding commands in HEX This list is provided as a reference only you do not have to manually enter commands Refer to the DDA Operation and Instruction Manual for a complete list of details for each command Command Description OA HEX Output level 1 product at 0 1 inch resolution OB HEX Output level 1 product at 0 01
