**ON A/C ALL
-The LS unswitched bus sends maintenance data (BITE contents) to the CFDIU (Refer to AMM 316900 00 EIS TEST/BITE).
3. Interface
_________
A. Interface Tables This table contains all the output parameters in the digital form. They are sorted as per the numerical order of their output label. The following table gives:
-SYS LABEL SDI: ouput label for which the parameter is available
-PARAMETER DEFINITION: parameter name
-RANGE ACCURACY: measurement range. Maximum value transmitted. When the digital value changes, the change step is equal to the accuracy
-UNIT: unit in which the digital value is transmitted
-SIG BIT: number of significant bits
-BIT: bit number used by the parameter
-UPD/MSEC: output transmission interval. The refresh rate is given in milliseconds
-CODE:
BNR : binary data word
BCD : binary coded decimal data word
ISO : data word coded in ISO 5 code
DIS : discrete data word
HEX : hexadecimal coded
HYB : mixed code
-ALPHA CODE: indicates the parameter mnemonic code
-SOURCE ORIGIN: parameter source computer or system.
