Enter the start command.

When the prompt DR>> is issued, type:

CHANGE HW?

Mode

You must answer Y to this query if you want to change the hardware parameter tables. The
program will then ask a number of hardware parameter questions in sequence. For example,
the first question is:

Normal operation
Auto echo mode
Local loopback
Remote loopback

# UNITS?

At this point, enter the number of units to be tested.
NOTE

Some versions of the diagnostic supervisor do not
ask the CHANGE HW? question at the first start

command. Instead they go straight into the hardware parameter question sequence.

The answers to the questions are used to build hardware parameter tables ( P-tables)in memory. A series
of questions is posed for each device to be tested. A hardware P-tableis built for each device.
3.

Answer the software parameter questions.

When all the hardware P-tables are built the program responds with:

Note

CHANGE SW?

After the DHVI11 is reset, CSR<3:0>
may point to a non-existent channel.
To access chanels 0 to 7, write
channel number to CSR<3:0>.

If other than default parameters are wanted for the software, type Y. If the default parameters
are wanted, type N

If you type Y, a series of software questions will be asked and the answers to these will be
entered into the software P-tablein memory. The software questions will be asked only once,
regardless of the number of units to be tested.
4.

Diagnostic execution

After the software questions have been answered, the diagnostic starts to run.

What happens next is determined by the switch options selected with the start command, or

errors occurring during execution of the diagnostic.
