NOTE: This length is NOT the same as the length of the packet. It tells how many

bytes follow in the "event/action" .

Response can be made up of the following elements. All elements except Numeric
2 are one byte. Numeric 2 is a 4-byte integer.

Note 1: For definition of event and action codes see

section 10.4.14 on page 10-21

for the Event list and

section 10.4.15 on page 10-24

for the Action list. The codes

sent via communications would be the number listed there. If the event is to be
negated, the event code will be negated as well. For example, the code for external
input is 0x41. To indicate not external input (that is, input not set) the code is 0xBF.
Action codes may not be negated.

Note 2: Numeric 1 is present if the event code requires a numeric. The range is
dependent on the specific code.

Note 3: Numeric 2 is present if the event code requires a second numeric. It is a
4-byte integer. The range is dependent on the specific code.

Note 4: The Action Numeric is present if the action code requires a numeric. The
range is dependent on the specific code.

The ordering of the logic elements is as follows: (The term Event Code includes
Negated Event Code)
