Section 3 —

Operation & Service

If all levels were connected to source 3 and protected, the query
response would be:

3C 08 SP000301 (Where level 00 indicates
all levels)

If levels 1 and 3 were connected to source 10 and level 2 to source
1 and unprotected, the response would be:

3C 10 SC000A01 SC020101

This response contains two S commands. In the first, level 00
indicates all levels are connected to source 10 (0A), but the second
indicates that level 2 is in fact connected to source 1 (takes
precedence over the first response). This technique reduces the
number of characters in the response message by using the all
levels value for the source connected to the greatest number of
levels followed by a specific message regarding sources connected
to other levels.

If level 1 were connected to source 3, level 2 to 8, and level 3 not
connected, the response would be:

3C 18 SP000301 SP020801 SP030001

Note that the first S command specifies level 00, not level 01. The
first S command in a status response is always for level 00 (all
levels).
