 2.H.
This parameter tells the ADC program where in the ARINC 429 interface card to put the SMRTCRD1.HEX program. The default is 0XA000. It is not necessary to change this parameter.
This parameter gives the location in the PC of the shared memory of the ARINC interface card. This value is on a label on the ARINC interface card. Use 0XD000 for an MCDU card and 0XD400 for an EFIS card. The default is 0XD000.
This parameter tells the ADC program which type of ARINC interface card is installed. Use 0X310 for an MCDU card and 0X300 for an EFIS card. The default is 0X310.

MAINTENANCE MANUAL

 (5)  
The ADC program makes two files when it runs, a data file and a log file. The data file contains the report that was sent to the PC. The log file contains the name of the data file (the TAIL parameter), the number of ARINC words received, and the time and date when the data file was made (the GMT and DATE parameters). When the data file closes, the data file name and an indication that the data is collected show on the PC.

 (6)  
The data file is kept as an ASCII text file. You can read the file with most line editors or with the DOS TYPE command.

 (7)  
The name of the data file is the TAIL parameter followed by the month and day the file was made. The file extension is the file type followed by the file count from the log file. For example, if the value of the TAIL parameter is TEST and the value of FILE_TYPE is A, the name of the first data file made on September 22 is TEST0922.A01.

 (8)  
The ADC program operates in the standby, active, inactive, and timeout modes.

 (a)  
The standby mode is when the program is prepared to receive data. The PC shows tildes during this mode.

 (b)  
The active mode of the program is when the PC receives data. The PC shows plus signs during this mode.

 (c)  
The inactive mode of the program is the time after the data input to the PC stops but before the program closes the data file. The PC shows asterisks during this mode.

 (d)  
The timeout mode of the program is when the data file closes after the time specified by the DATA_TIMEOUT parameter. The PC shows carets during this mode.

 (e)  
The standby mode begins again when the file closes.
