Management Stream Values to Disk The Display command displays the current channel value of the assigned channel in the Value column miy of the DBK70 Channel list For any assigned channel if the DBK70 does not find a header that matches the filter no value will be reported Typical networks broadcast some messages more often than others so it is not unusual to see some channels updating faster than others Clicking the button in the toolbar will enable the display Pushing it a second time turns the display off z The Stream to Disk command records all channel values to disk using the filename assigned using the command Channel Management Set Data Destination Filename Note The DBK70 s analog output will proportionately track your parameter with 16 bit resolution but only integer values are reported to the PC Ifthe parameter of interest has a relevant fractional component that needs to be reported on the PidPRO screen use the Raw gt Units Conversion fields in the Database Item View to rescale your parameter so that the fractional component is not truncated For additional information refer to the Raw gt Units Conversion Method section on page 5 24 of this document Set Data Destination File Name PidPRO Only Menu Channel Management Set Data Destination Filename This command pops up a dialog box allowing the selection of a filename that can be later used as a destination file for the command Stream Values To Disk see above

Output Channel Icon These parameters and the data display process will be described in further detail below The scaling process used here is the same process used to calculate the SRD Mathematically the SRD is interpreted as a 32 bit signed integer value 1 e a long integer in C The SRD is the result of multiplying the received data by the Output Scale and adding to the result of the multiplication the Output Offset and then converting the result this addition into an 32 bit signed integer value 1 e y mx b where SRD integer of the y value where x is the received data m is the scale value b is the offset value and y the result of the scaling process The received data is the data from a message that was received from a vehicle data bus and passed through the Filter defined for an output channel The Index and Length specify where in the received message the data starts and how long it is Storage Type specifies whether the received data is interpreted as either a signed or an unsigned value The Output Scale and Output Offset values may be positive or negative and may be defined in an integer or floating point form 1 e floating point means defined with a decimal point and with or without fractional values An SRD may be a positive or a negative value The signal generated by an output channel is determined by the SRD s value and the way a given output channel processes that value Storage Type Output Mode and Aux Value dete
