Parameters
 Timeout time [63,0,171] used in case of
auxiliary data item display prompt, i.e. when
auxiliary data index [63,0,178] less than
Number of data items [63,0,186]
 Auxiliary data index indicates that which
prompt should be displayed and which place
user entry should be stored.
Results
The operator has to enter an auxiliary data item
within the timeout time [63,0,171]; otherwise the
operation aborts and sets the Operation Timed
Out flag (bit 3 in [63,0,119]).
If you set the timeout to zero, then the timeout
doesn’t occur. You must then use the Timeout
Operation command (0x5) to end this operation.
If timeout occurs then the DL8000 displays the
message "Timeout Operation" and waits for next
command from the TAS.
When an operator enters an auxiliary data item,
then the DL8000 clears the Operation Timed Out
and the K&D Locked Out flags. It also sets the
Keypad Data Available flag, which tells the TAS
that the operator has entered data. The DL8000
displays a “Data Entered” message and waits for
the next command from the TAS.
After this the TAS can read data item
[63,0,188;190;192;194;196] from the appropriate
parameter based on auxiliary data item index
[63,0,178].
